I bought a used saw without a manual. This video did a great job showing me how to tune up the saw and where the adjustments were in a clear concise manner. Well done!
Just bought this saw, got it out of the box and attached it to the fold up table. Next job is to set up the blade. This very timely and down to earth video should save me plenty of time and headaches. Thanks.
Awesome! Just take your time and be patient and it should all go just fine! You can always tweak it again later if you find something off once you start using it too...
Love the BOSCH saw, and loved the very detailed explanation of how to set or adjust the saw. Will be getting this along with the mobile stand. Will convince both my wife and daughter to get me the stand first for FATHERS day, and get the saw by myself. You sir just earned a sub and a like. Love how you your time, and were very patient with making those infinite adjustments. This video is added to my playlist. I will be reverting to this particular video to make my adjustments once I get it. Very well down sir, I will be back for more of your videos in the future. Thank you for this.
OMG! You are the only one being able to explain all the necessary steps in one cool video! I am German and after wasting so much time, I finally stumbled upon this!!! Thank you so much and all the best wishes to you
Thank you for the video! imo - the easiest way to check for main square cut is to get a reasonably sized piece of wood and cut it and check it using your square. And then flip it over and cut again and check for square. That seemed to do the best for me. Also, thank you for trying different ways to show how to make it square. Hope it helps others. Finally, thanks for not editing your video to make it look easy - while it's not terribly difficult, there is a lot of tweaking here and there to get it perfect.
thanks for the feedback! Someone else recommended a digital angle finder that is magnetic and attached to the sawblade. I'm going to have to pick one up and try that out in the future for the bevel cuts. It's definitely a lot of small tweaks back and forth. A little too far one way, not far enough, then too far, over and over. hahaha.
My saw arrived with the adjustment bolts on the back of the saw tightened down. No way to bevel. You showed the quick adjustment and now the bevel mechanism works as it should. Thank You!!!
This is an excellent tune up video and much appreciated. I realize that it's 3 years old but I just received this saw last night from Home Depot delivery. I unpacked it and was just making certain that everything moved before ever plugging it in. I tilted the bevel to maximum left bevel and now it won't move back to vertical. No slop, nothing. Just jammed at 47 degrees left. I'm going to try these bevel adjustment tips to see if I can free it up before tuning it up. Okay I fixed it. Just loosen the biggest nut in the rear.
Thank you for posting this video. I bought the saw about a year ago and was naive in thinking Bosch would have set it up decently upon delivery, given the price point of the item. Boy was I wrong... Had to bodge a few mitres just now, was fed up with angles being off and found your video.
Got frustrated with this mitre saw after some time. Finally this excellent video got the saw cut square and true. Heaps of thanks from Down Under🙏🙏🙏🙏🙏🙏
AWESOME!!!!!! Glad it was helpful! Can't say I love the saw but it cuts okay. My old DeWalt seemed to be more accurate but it was broken and needed to be replaced and this is what I got
Thank you for the video. I was looking at miter saws last week and ended up sold on the Bosch. It will still be a month or two before I get it, but youve put a lot of my worries to rest already. Reading the online reviews ( I always start by reading the 1 srar reviews) a lot of folks complained that right out of the box it wouldnt cut square and there were no adjustments for it. 😢. Their loss. I was blown away by the smoothness of the Glide system. I will be using it primarily for making segmented rings which will be glued together and turned into bowls, urns, etc.
Not sure about the new ones, but the GCM12SD's from before 2020 could not be adjusted to do both a square cut when doing a chop and a square cut doing a slide. You had to choose one or the other because all you can control is the bed and fence, not the path of the blade when extended. The blade shaft is slightly out of alignment with the arm. Adjusting the bed and fence can't fix that. I've been trying to find a solution for 5 years.
This video is a great help.. i have same bosh model and same issues.. miter saw is brilliant in a way however must be precisely adjusted and here you are coming with your great tutorial!! Cheers
Thanks for showing me how to adjust the lock from the rear of the saw. The wing was so tight it interfered with wide boards, now I can adjust it so that it is below the top!

Damn! Nick. You look like a movie star!! I just joined a communal shop in Raleigh NC, called ShopSpace, so I could do a little more woodworking than I could in my one car garage. They've got one of the Bosch Dual bevels; lo and behold, nobody new how to adjust it. So, here I am at 4 in the morning looking for TH-cams and who do I find--Nick Borsellino!!! I guess I'll get into the video now. Great to see you. Best regards, brother. Devin Dascher
SWEET! How do you like it? I haven't really used mine much and I'm finding it hard to get used to and I'm not terribly pleased with the accuracy of the cuts. Like when I make a 45 degree bevel it makes a curve in the bevel so only the center of the board touches the other miter. It is so weird!
@@BorsellinoHomeServices hmmm. Have you had problems with blade wobble? I hear that’s not uncommon for 12 inch blades. I used the classic dealt 12 inch for years with out that issue. I’ve used this saw for like 2 years now but not all the time and I notice that problem sometimes but not all the time. I figured it was operator error lol.
@@mo.ripples YES! I don't think it's operator error. I have issues with wobble on the 12" blade and honestly, I) wish I bought the 10" version instead of this monster.... I still might buy it and "downgrade". I came from the DWS 782 which was an amazing saw but started having some blade wobble after my dog knocked over my saw on the stand... DOH
*Great machine for the price! Pretty powerful **MyBest.Tools** and light to carry around the home. I definitely recommend this saw for any homeowner. Also, came with an extra blade. I was very satisfied with the overall quality and price.*
You say it's easy to carry around the house? I have one and it weighs 67 lbs. I carry my work to it. It is a great saw and mine came out of the box set up spot on.
Just purchased this saw but have not set it up yet. Looks pretty straight forward. TY for making this video, should help me out when I get aroubd to adjusting all the blade angles which will be soon.
To adjust the main cut at 90 degrees, I have found it very helpful to use a pair of Rockler micro adjusters for the router table. When these are sold, they all "face" in the same direction, but it is very easy to reverse one of them (you unscrew the part that touches what you are going to adjust, take the long screw out of the clamp and screw it into the clamp in the opposite direction, and then screw the face part back in). It is then possible to clamp one of these to each side of the board the saw is attached to, lining them up so that one presses on the right side of the saw and the other on the left. This enables you to make fairly small adjustments to the position of the saw; you just unscrew one a little and then screw the other one in a little more. This is a lot better than whacking the saw one way and, when that proves too far, whacking it in the other direction and hoping that you luck out.
is this what you're talking about? www.rockler.com/micro-adjuster-for-router-table-fence I just can't for the life of me figure out how I would attach that to my saw to adjust the angle
yeah basically use whatever works for you. Framing squares can get out of square and you can recalibrate them so I always check left and right sides. And no square will be 100% dead on, or at least it's near impossible so always double and triple check everything every way you can :)
This was an absolutely fabulous done Vedic. I might have missed it but i don’t rember hearing you mention the sizes of the used sockets nor the Allen keys. Thank you.
Great video. Thanks. I have the 10 inch saw which is just slightly different but the way you did things was extremely helpful. I wish you would do one on the 10 inch version. Thanks so much!
Thanks! Honestly, I wish I bought the 10 inch instead of the 12. I think this has too much blade deflection and wobble overall. Plus it is really heavy and awkward to pick up. Much harder than my old dewalt to transport.
@@BorsellinoHomeServices The Bosch 10 inch is only 1 pound lighter than the 12 inch according to another TH-cam video I watched. It is no picnic to move around, especially at my age! Anyway, your video really helped me to understand the tuning up process. A tiny bit different on the 10 inch but still much more doable after watching your excellent video.
No problem. I'm glad to hear you love it! I honestly haven't used it much cause I've got my business on hold for plow season. I don't bother with the construction in the winter here cause I hate working in the snow. I'll be using it a lot more soon though!
i didn't know milwaukee made a space saving saw... I'll be honest, after owning this thing for a while I don't love it. In fact, I liked my old dewalt better. But I needed the space saving to fit it into my trailer shop setup
@@BorsellinoHomeServices not a space saver, just a sliding miter saw. 6955-20, in my opinion is more of finicky. Though being a milwaukee well built. I tested a makita was not to fond of it, feels odd, makita does contractor grade tools. I have a portable table saw, it's a work horse.
I returned my first saw because it too was out of square and bevel was off and no matter what adjustments I did as per the manual, it was always off. Either the left side would true up but the right side was off and vise versa. I ended up calling Bosch and the tech guy basically said it’s probably a defective saw and the option were to have them service it or I go back to Depot to exchange it. I ended up exchanging it and the replacement saw right out of the box was spot on square and bevel. I did notice on the original saw that the spacing from the table to the underside of the fence on the left was less than on the right side. The new one has equal spacing. So just exchange it for a good one. Overall I am very disappointed with Bosch’s quality control to allow this issue that so many others are having. I didn’t want to give up on it because Lowe’s had it on sale and depot did the price match plus 10%. also after speaking to depot customer service regarding this saw they took another $30.00 off, so I ended up paying only $599.00 + HST. Nice!
Great video, but god this saw has so many steps to do anything to. lol.. It ate up a good portion of my day doing these adjustments vs actually working. Hope it stays perfect for a long time!
Yeah it is a pain to setup for sure. I haven't readjusted mine since I made this video but I don't use it very often and when I do it cuts good for me. If I was going to do a job that needed exact precision I might check it over again
@@BorsellinoHomeServices out of curiosity, how tight are the detents at 0, 22.5, 45, etc. On DeWalt and Makita saws they're very tight--you don't even need to lock it off. But when I tried the Bosch at the store it just seems sloppy. Moves a good 1/16". Not sure if that's HD people putting it together sloppy or if it's just got that slop. I expect the slop from a Harbor Freight saw. But when I'm spending $600, I expect more.
sweeeeeeeeeeeet! I don't think I've had to adjust mine since and it still cuts fairy straight. Although I'm disappointed in overall quality of the saw. It has inconsistencies in the cutting
This helped me a lot, just bought one! I think your ref. in title is wrong: the 'SD' is the one with the Rail, this is the GCM12 GDL (at least in Europe). Cheers from France!
Nope it's correct. Here's a link to Bosch's website... definitely SD. But thanks for the heads up I'm assuming it's just different in Europe (which is odd) www.boschtools.com/us/en/boschtools-ocs/miter-saws-gcm12sd-33969-p/
I adjusted it again after using it for a few months and was able to get it much better. Just needed some time to wear itself in I guess. The only thing I don't like is there seems to be something off with the knuckle which is not adjustable... Doesn't seem sturdy enough or something so the blade deflects. I'm not explaining it even properly cause I don't know how to explain it
maybe Bosch should put this on their website, i just picked up this saw i am a beginner at woodworking its probably more saw than i need but i had just bought the Metabo 10 inch zero clearance miter saw, it is a good saw but at 399 plus tax 430 and change i saw this saw on marketplace for 500 brand new in box so for 70 more dollars i figured why not, i do like Bosch equipment i have their drill, impact wrench, jig saw, circular saw all 18 volt what i like about the circular saw is that the blade is to the left if that makes sense, great video.
@@BorsellinoHomeServices thanks that's why when I saw it listed I told him I was interested but I wasn't able to get to Lowes until the following day to return my Metabo he was fine it all worked out for 70 bucks difference better saw, I do have the Metabo 10 inch jobsite table saw and like it that was another good deal, holiday price at Lowes was 329 down from 529, two weeks later 299 so I got more cash back. Great videos also.
My machine fell accidentally while moving it and the angles misaligned, and I've been so frustrated not knowing what to do, but I hope I'll be able to make a significant change after watching this video. Thank you
@@BorsellinoHomeServices I tried to do the adjustments, maybe not 100% to the original factory settings, but it seems much better than before I watched your video, because I was a little bit weary causing more misalignments. Thanks a mil for sharing your experience.
Appreciating the effort in doing this. I would make one recommendation, a more robust/rigid table would be better. The amount of motion would hinder your ability to get things set properly.
Edit: after completely hating this saw for 8 years, I gave it another go at squaring and used the test cut over and over method you wound up with. Needless to say, first perfectly square cuts ever with this saw! Thank you for getting me to be more patient!!! Original: I have never in 8 years been able to get this saw square. Square all you want then pull the lever and it magically racks out of square. The absolute worst saw for me.
I'm glad that I was able to help you make your saw cut nice! I can't say I love this saw though I think it has too much wobble and deflection in the arm mechanism
I’m contemplating buying my first mitre saw. It’s either this or the Dewalt DWS780. I’ve been afraid of getting the Bosch because of this reason with the adjustments needed after cuts which sounds annoying but based on this comment, it’s seems the “cut over cut” method might do the trick. But then you’re mentioning wobble now?
Hi. I just got this saw and really appreciated your video, so thanks for that. Having said this, I have a slight "issue". My first cut did not go "through" all the way. What I mean by that is that the blade moved not far enough (away from you) to cut all the way through the piece of wood... Why would that be? I see all kind of stops build into this thing, but could not find one that would limit the travel back and forth!? Any idea? Thanks.
That's odd. I have noticed that it barely cuts through that bottom back side and I often wonder if it cut it all the way. Are you using the blade that came with it or something else? The only thing I can think is that there is something stuck somewhere like styrofoam packaging or something inside the knuckle?
@@BorsellinoHomeServices Hi. Sorry for the late reply... I am using the blade that came with it. However, I made a few more test cuts and they all went all the way through this time. However, I feel like I have to push harder than I should, in order to make the cuts all the way through. I will check for something stuck in between though. Thanks.
Thanks very much. I’ve had such a hard time getting this saw square and kinda a piss off it doesn’t come calibrated properly for the price you pay. I’ve don’t this before and given up, but I’ll try it again!
I am not particularly happy with the saw. I only bought it because of the knuckle system so I could keep it set up in my trailer but it doesn't make good cuts even after precisely setting it up. Feels like I got ripped off...
@@BorsellinoHomeServices yes I feel the same. I too got it for the arm and low profile keeping it against a wall. I’m looking at getting a 12” non sliding mitre saw just for better more dependable cuts.
Thanks Excellent video - I have it square - but I can no longer lock in the 0 deg pin.....it seems that when I aligned it - the pin wont go in - it goes in for 30 deg bot not 45 or 0 - any suggestions
so you can't cut square??? I would just start taking stuff apart in the area the problem is until you figure it out. work backwards and keep track of what you took apart
Hi, Thank you so much for the great vedio. I am planning to buy this saw. It would be my first miter saw. So would you recommend this saw in any case? Thanks again and appreciate your reply.
It might be a little overkill for what you need. I really liked my DeWalt saw, the only reason I upgraded this was for the extra space behind it building it into my mobile shop trailer
I’m having trouble with both the handle to allow/unlock the angle right and left and you showed how to rectify that. But the bevel knob that allows tilt right and left is so impossible to turn I feel to force it will break it. How do I loosen this one?
hmmm, if i didn't cover it in this video then chances are I haven't adjusted it myself either. Just trace it backwards and see if you can find a nut or bolt or something somewhere
Thanks for this video. Wish I had found it sooner. I had been fighting with non-square cuts for awhile and could not figure out what was wrong. Do you know how to adjust the rotating base? Mine is extremely tight and difficult to turn.
13:30 AEST . Can it be assumed the bevel lock pin has been applied (pushed in) prior to each adjustment ? It appeared pulled out , and not mentioned throughout video. Very well explained, thankyou
you talking about the pin that holds the blade in the downward position while i'm checking with a square? I do push that in and pull it out to hold the blade down versus holding the blade down with my hand. holding it manually could cause the saw to flex and be inaccurate although the reality is when you cut you're using your hand so maybe i shouldn't use the pin for adjusting.
Like you video. Still trying to figure out if the depth of cut can be easily set for cutting notches like my old Hitachi slide miter saw did with a thumb screw.
I saw a test where several shallow cuts (not all of the way through)were made on the sane board without moving the board; to check the repeatability (or reliability) of the cuts. with several consecutive passes, the cut got wider, demonstrating that there was flex in the glide system as it is moved back and forth. Have you checked that?
I haven't tried that but i believe it! I feel like there is waaaaaaaay too much play in the system. It's definitely not as heavy duty as my old dewalt with sliding rail system. I have to be very careful when making cuts to not pull it side to side
Added note: If you read the negative reviews on Bosch's website, you will find several who complain about the blade not tracking properly. I've also seen similar posts in several woodworker's forums. Many of these people either returned or sold their saws due to this unsolvable problem.
Hi, great video, thanks. Do you know how to adjust the laser lines? Mine seem to not match up with the blade - like .5 - .75mm out which is not good. Thanks - am getting a lot out of your content - am an apprentice carpenter in New Zealand.
My saw doesn't have a laser on it. Hmmm, I didn't even know that was an option. I'm glad to hear you are enjoying my videos! Let me know if there's anything specific that you're interested in me covering and I'll see if I can touch on it for you.
Yes you remove the large black cover from the top of the laser first then you adjust with an allen key on the side for side to side movement and the front top adjustment for angle. Bosch has a downloadable manual which covers this, but annoyingly only by pictures and no text.
Howdy, have just done the adjustment - easy. The adjustment screws are accessible without removing the cover - although the manual says a 2mm hex driver, it’s a 2.5 mm. Not a big deal but as far as accuracy of info in the manual goes it’s a problem ie what else is not correct? Anyway, thanks for the help.
@@BorsellinoHomeServices I’ve got the 18V model so it’s probably just an extra feature on a different saw. However all the adjustments you made are still the same on my saw as for yours.

I have the Bosch GCM 12 GDL with the same problems, very grateful to you for the good explanation. I hope I can fix it. Keep it up. Regards from Chile.
You're welcome! I really hope this helps!
Damn! Nick. You look like a movie star!! I just joined a communal shop in Raleigh NC, called ShopSpace, so I could do a little more woodworking than I could in my one car garage. They've got one of the Bosch Dual bevels; lo and behold, nobody new how to adjust it. So, here I am at 4 in the morning looking for TH-cams and who do I find--Nick Borsellino!!! I guess I'll get into the video now. Great to see you. Best regards, brother. Devin Dascher
ATM my Glide is running true but so happy i found your video for future reference, Thanks from the UK
Awesome! Thanks for the comment!
Great straight forward adjustment guide. I really like all the comments on the saw too.
Thanks for the feedback! A bunch of people have said I didn't do the 45 adjustments clear enough so I hope you can figure it out!
Nice job! You explained that really well. My big take away...I need to slow down, be more patient and take my time. Thanks!
patience is key in woodworking!
I have this exact miter saw. Amazing tutorial brother! This will save me a lot of time tuning it up later today.
SWEET! How do you like it? I haven't really used mine much and I'm finding it hard to get used to and I'm not terribly pleased with the accuracy of the cuts. Like when I make a 45 degree bevel it makes a curve in the bevel so only the center of the board touches the other miter. It is so weird!
So howdo you like it??
@@BorsellinoHomeServices hmmm. Have you had problems with blade wobble? I hear that’s not uncommon for 12 inch blades. I used the classic dealt 12 inch for years with out that issue. I’ve used this saw for like 2 years now but not all the time and I notice that problem sometimes but not all the time. I figured it was operator error lol.
@@mo.ripples YES! I don't think it's operator error. I have issues with wobble on the 12" blade and honestly, I) wish I bought the 10" version instead of this monster.... I still might buy it and "downgrade". I came from the DWS 782 which was an amazing saw but started having some blade wobble after my dog knocked over my saw on the stand... DOH
*Great machine for the price! Pretty powerful **MyBest.Tools** and light to carry around the home. I definitely recommend this saw for any homeowner. Also, came with an extra blade. I was very satisfied with the overall quality and price.*
thanks for the input!
You say it's easy to carry around the house? I have one and it weighs 67 lbs. I carry my work to it. It is a great saw and mine came out of the box set up spot on.
I've been looking for how to adjust this saw for years. Thanks mate that's super helpful
awesome!!! Hopefully you get it nice and square now!
Just purchased this saw but have not set it up yet. Looks pretty straight forward. TY for making this video, should help me out when I get aroubd to adjusting all the blade angles which will be soon.
you're welcome! thanks for checking it out!
To adjust the main cut at 90 degrees, I have found it very helpful to use a pair of Rockler micro adjusters for the router table. When these are sold, they all "face" in the same direction, but it is very easy to reverse one of them (you unscrew the part that touches what you are going to adjust, take the long screw out of the clamp and screw it into the clamp in the opposite direction, and then screw the face part back in). It is then possible to clamp one of these to each side of the board the saw is attached to, lining them up so that one presses on the right side of the saw and the other on the left. This enables you to make fairly small adjustments to the position of the saw; you just unscrew one a little and then screw the other one in a little more. This is a lot better than whacking the saw one way and, when that proves too far, whacking it in the other direction and hoping that you luck out.
is this what you're talking about? www.rockler.com/micro-adjuster-for-router-table-fence
I just can't for the life of me figure out how I would attach that to my saw to adjust the angle
@@BorsellinoHomeServiceshe never replied
Thanks so much for a great video - I had been putting this off with this saw - thanks to your easy to follow instructions it made it a breeze.
You're welcome! I set mine up once and it's stayed pretty much perfect since
Speed square and the framing square are my go to Items to recalibrate. Never used the Tri square for this
yeah basically use whatever works for you. Framing squares can get out of square and you can recalibrate them so I always check left and right sides. And no square will be 100% dead on, or at least it's near impossible so always double and triple check everything every way you can :)
I just bought one of these. I appreciated your video very much. Thanks for the demonstration.
absolutely! hope this helps!!!
Excellent video! Nothing but information presented as quickly as humanly possible without losing clarity. Bravo.
hey thanks!!! I'm glad you found it informative without too much fluff
This was so incredibly clear and helpful. Thank you so much
You are very welcome!!!
This was an absolutely fabulous done Vedic. I might have missed it but i don’t rember hearing you mention the sizes of the used sockets nor the Allen keys. Thank you.
thank you. It's in the video in the tools needed section at 2:41 4mm and 6mm
@@BorsellinoHomeServices thank you. Great video, again thanks.
Thank you so much for this video, it is making setting up my saw so much easier!
awesome glad it's helpful!
Thanks for making this simple because of you I was able to adjust my saw as well. 🙌
Whoop Whoop!!! Glad it was helpful!
Just bought this saw today and really appreciate the tutorial. Legend cheers!!!
Thanks! I didn't like the saw at first but it is growing on me
Great video. Thanks for taking the time to record it.
THX, Very straight forward and easy. Fellow carpenter.
Thank you so much.
I'm not happy with my 45° cuts. They do not end up making square. Hopefully after I do what you illustrated I'll have better luck
Great video. Thanks. I have the 10 inch saw which is just slightly different but the way you did things was extremely helpful. I wish you would do one on the 10 inch version. Thanks so much!
Thanks! Honestly, I wish I bought the 10 inch instead of the 12. I think this has too much blade deflection and wobble overall. Plus it is really heavy and awkward to pick up. Much harder than my old dewalt to transport.
@@BorsellinoHomeServices The Bosch 10 inch is only 1 pound lighter than the 12 inch according to another TH-cam video I watched. It is no picnic to move around, especially at my age! Anyway, your video really helped me to understand the tuning up process. A tiny bit different on the 10 inch but still much more doable after watching your excellent video.
@@dwayneford1990 Oh wow good to know. I had just figured it was way smaller! I'm glad you found the video helpful!!
Excellent video. I really appreciate you making this. It's going to help me adjust my saw. Thanks again!
hope it is helpful!
Just got this saw. Very helpful video tour!
glad it was helpful!!
Thanks for confirming this process. Love this saw.
No problem. I'm glad to hear you love it! I honestly haven't used it much cause I've got my business on hold for plow season. I don't bother with the construction in the winter here cause I hate working in the snow. I'll be using it a lot more soon though!
That video will save me time for my set up on mine! Thank you!!
Hope it helps! You're welcome
I was debating Milwaukee or Bosch.
I believe the decision has been made Bosch.
i didn't know milwaukee made a space saving saw... I'll be honest, after owning this thing for a while I don't love it. In fact, I liked my old dewalt better. But I needed the space saving to fit it into my trailer shop setup
@@BorsellinoHomeServices not a space saver, just a sliding miter saw.
6955-20, in my opinion is more of finicky. Though being a milwaukee well built.
I tested a makita was not to fond of it, feels odd, makita does contractor grade tools.
I have a portable table saw, it's a work horse.
This video is really very helpful. Thanks for making it!
Awesome! Glad it was helpful!
Thanks from germany. Good job. You made my day!
I would tighten those bolts down like a car tire. Switch back and forth between the sides and tighten them a little at a time.
good tip!
I returned my first saw because it too was out of square and bevel was off and no matter what adjustments I did as per the manual, it was always off. Either the left side would true up but the right side was off and vise versa. I ended up calling Bosch and the tech guy basically said it’s probably a defective saw and the option were to have them service it or I go back to Depot to exchange it. I ended up exchanging it and the replacement saw right out of the box was spot on square and bevel.
I did notice on the original saw that the spacing from the table to the underside of the fence on the left was less than on the right side. The new one has equal spacing. So just exchange it for a good one. Overall I am very disappointed with Bosch’s quality control to allow this issue that so many others are having. I didn’t want to give up on it because Lowe’s had it on sale and depot did the price match plus 10%. also after speaking to depot customer service regarding this saw they took another $30.00 off, so I ended up paying only $599.00 + HST. Nice!
DANG! Good price! I imagine I'm out of the timeframe where they would let me return it but maybe not??
Great video, but god this saw has so many steps to do anything to. lol.. It ate up a good portion of my day doing these adjustments vs actually working. Hope it stays perfect for a long time!
Yeah it is a pain to setup for sure. I haven't readjusted mine since I made this video but I don't use it very often and when I do it cuts good for me. If I was going to do a job that needed exact precision I might check it over again
Great video
Can’t wait to get home and check mine.
hope it helps
Thank you so much for this tutorial it will come In Handy !
Absolutely! Hope it helps!
That broken wrench is about my experience with all of Bosch's products lately. Trading on the brand name and cheaping out on quality.
It's really too bad that that's where they cheap out... on the freakin alan wrench. Makes you wonder what else they cheap out on???
@@BorsellinoHomeServices out of curiosity, how tight are the detents at 0, 22.5, 45, etc. On DeWalt and Makita saws they're very tight--you don't even need to lock it off. But when I tried the Bosch at the store it just seems sloppy. Moves a good 1/16". Not sure if that's HD people putting it together sloppy or if it's just got that slop.
I expect the slop from a Harbor Freight saw. But when I'm spending $600, I expect more.
wow thanks a lot for sharing this that will surely resolve my issue with this saw 👍
sweeeeeeeeeeeet! I don't think I've had to adjust mine since and it still cuts fairy straight. Although I'm disappointed in overall quality of the saw. It has inconsistencies in the cutting
Thanks for making the video, very informative.
You're very welcome! Thanks for the comment!
This helped me a lot, just bought one! I think your ref. in title is wrong: the 'SD' is the one with the Rail, this is the GCM12 GDL (at least in Europe). Cheers from France!
Nope it's correct. Here's a link to Bosch's website... definitely SD. But thanks for the heads up I'm assuming it's just different in Europe (which is odd) www.boschtools.com/us/en/boschtools-ocs/miter-saws-gcm12sd-33969-p/
I got the same saw. Checked the angles setting it up like you should when you get a new saw and everything was perfect so IDK
I adjusted it again after using it for a few months and was able to get it much better. Just needed some time to wear itself in I guess. The only thing I don't like is there seems to be something off with the knuckle which is not adjustable... Doesn't seem sturdy enough or something so the blade deflects. I'm not explaining it even properly cause I don't know how to explain it
maybe Bosch should put this on their website, i just picked up this saw i am a beginner at woodworking its probably more saw than i need but i had just bought the Metabo 10 inch zero clearance miter saw, it is a good saw but at 399 plus tax 430 and change i saw this saw on marketplace for 500 brand new in box so for 70 more dollars i figured why not, i do like Bosch equipment i have their drill, impact wrench, jig saw, circular saw all 18 volt what i like about the circular saw is that the blade is to the left if that makes sense, great video.
Cool! I hope you like it. $500 is a steal for this saw!
@@BorsellinoHomeServices thanks that's why when I saw it listed I told him I was interested but I wasn't able to get to Lowes until the following day to return my Metabo he was fine it all worked out for 70 bucks difference better saw, I do have the Metabo 10 inch jobsite table saw and like it that was another good deal, holiday price at Lowes was 329 down from 529, two weeks later 299 so I got more cash back. Great videos also.
@@sflagg0817 sweet. thanks for the feedback! :)
My machine fell accidentally while moving it and the angles misaligned, and I've been so frustrated not knowing what to do, but I hope I'll be able to make a significant change after watching this video. Thank you
hopefully you didnt bend anything! My old dewalt fell once and was never the same after.
@@BorsellinoHomeServices I tried to do the adjustments, maybe not 100% to the original factory settings, but it seems much better than before I watched your video, because I was a little bit weary causing more misalignments.
Thanks a mil for sharing your experience.
So thankful for your video!
You're very welcome!
Thank you! My saw too needs calibrated out of the box. It is cutting crooked like yours.
hope it helped cut better!
Appreciating the effort in doing this. I would make one recommendation, a more robust/rigid table would be better. The amount of motion would hinder your ability to get things set properly.
Great instructions - thanks so much.
you are very welcome!
Great video !
many thanks very useful info mate.
Thanks for the vid bro! Very helpful
Awesome! Thanks for the feedback!!!
thank you very much brother! hello from chile
Great video. Thanks for sharing!
Great video.
Edit: after completely hating this saw for 8 years, I gave it another go at squaring and used the test cut over and over method you wound up with. Needless to say, first perfectly square cuts ever with this saw! Thank you for getting me to be more patient!!!
Original: I have never in 8 years been able to get this saw square. Square all you want then pull the lever and it magically racks out of square. The absolute worst saw for me.
I'm glad that I was able to help you make your saw cut nice! I can't say I love this saw though I think it has too much wobble and deflection in the arm mechanism
I’m contemplating buying my first mitre saw. It’s either this or the Dewalt DWS780. I’ve been afraid of getting the Bosch because of this reason with the adjustments needed after cuts which sounds annoying but based on this comment, it’s seems the “cut over cut” method might do the trick. But then you’re mentioning wobble now?
Thanks for this awesome video
Thanks for letting me know you liked it!!! I'm glad it was helpful!
Hi. I just got this saw and really appreciated your video, so thanks for that. Having said this, I have a slight "issue". My first cut did not go "through" all the way. What I mean by that is that the blade moved not far enough (away from you) to cut all the way through the piece of wood... Why would that be? I see all kind of stops build into this thing, but could not find one that would limit the travel back and forth!? Any idea? Thanks.
That's odd. I have noticed that it barely cuts through that bottom back side and I often wonder if it cut it all the way. Are you using the blade that came with it or something else? The only thing I can think is that there is something stuck somewhere like styrofoam packaging or something inside the knuckle?
@@BorsellinoHomeServices Hi. Sorry for the late reply... I am using the blade that came with it. However, I made a few more test cuts and they all went all the way through this time. However, I feel like I have to push harder than I should, in order to make the cuts all the way through. I will check for something stuck in between though. Thanks.
Thanks very much. I’ve had such a hard time getting this saw square and kinda a piss off it doesn’t come calibrated properly for the price you pay. I’ve don’t this before and given up, but I’ll try it again!
I am not particularly happy with the saw. I only bought it because of the knuckle system so I could keep it set up in my trailer but it doesn't make good cuts even after precisely setting it up. Feels like I got ripped off...
@@BorsellinoHomeServices yes I feel the same. I too got it for the arm and low profile keeping it against a wall. I’m looking at getting a 12” non sliding mitre saw just for better more dependable cuts.
Thanks Excellent video - I have it square - but I can no longer lock in the 0 deg pin.....it seems that when I aligned it - the pin wont go in - it goes in for 30 deg bot not 45 or 0 - any suggestions
so you can't cut square??? I would just start taking stuff apart in the area the problem is until you figure it out. work backwards and keep track of what you took apart
Very thorough. Thanks for sharing this info!
Glad you enjoyed it!
Hi,
Thank you so much for the great vedio.
I am planning to buy this saw. It would be my first miter saw. So would you recommend this saw in any case?
Thanks again and appreciate your reply.
It might be a little overkill for what you need. I really liked my DeWalt saw, the only reason I upgraded this was for the extra space behind it building it into my mobile shop trailer
Well done bro !.thanks for this video !
Hey! Thanks and you're welcome!
Awesome video highly recommend
thanks!
excellent video, thank you!
Thanks! And you're welcome!
I’m having trouble with both the handle to allow/unlock the angle right and left and you showed how to rectify that. But the bevel knob that allows tilt right and left is so impossible to turn I feel to force it will break it. How do I loosen this one?
hmmm, if i didn't cover it in this video then chances are I haven't adjusted it myself either. Just trace it backwards and see if you can find a nut or bolt or something somewhere
Very good video
Thanks for the feedback!
Thanks for this video. Wish I had found it sooner. I had been fighting with non-square cuts for awhile and could not figure out what was wrong.
Do you know how to adjust the rotating base? Mine is extremely tight and difficult to turn.
hmmmm unless it's in this video, that's an adjustment I am unaware of...
Saludos desde Ecuador felicitaciones por su compra y por compartir,, pregunta que origen de fabricación es dicha máquina??,,y si tiene Lacer
sorry i don't speak your language
for accurate 45deg and 90, i learned you can get a cheap plastic drafting 45. I use it for setting tools before getting engineer squares
good to know thanks!
Great video. Thanks!!!
Glad you liked it!
13:30 AEST . Can it be assumed the bevel lock pin has been applied (pushed in) prior to each adjustment ? It appeared pulled out , and not mentioned throughout video.
Very well explained, thankyou
you talking about the pin that holds the blade in the downward position while i'm checking with a square? I do push that in and pull it out to hold the blade down versus holding the blade down with my hand. holding it manually could cause the saw to flex and be inaccurate although the reality is when you cut you're using your hand so maybe i shouldn't use the pin for adjusting.
Like you video. Still trying to figure out if the depth of cut can be easily set for cutting notches like my old Hitachi slide miter saw did with a thumb screw.
thanks ralph! yeah I'm not 100% sure but I don't think so. Just one stop fully down for transport.
I saw a test where several shallow cuts (not all of the way through)were made on the sane board without moving the board; to check the repeatability (or reliability) of the cuts. with several consecutive passes, the cut got wider, demonstrating that there was flex in the glide system as it is moved back and forth. Have you checked that?
I haven't tried that but i believe it! I feel like there is waaaaaaaay too much play in the system. It's definitely not as heavy duty as my old dewalt with sliding rail system. I have to be very careful when making cuts to not pull it side to side
Added note: If you read the negative reviews on Bosch's website, you will find several who complain about the blade not tracking properly. I've also seen similar posts in several woodworker's forums. Many of these people either returned or sold their saws due to this unsolvable problem.
Hi, great video, thanks. Do you know how to adjust the laser lines? Mine seem to not match up with the blade - like .5 - .75mm out which is not good. Thanks - am getting a lot out of your content - am an apprentice carpenter in New Zealand.
My saw doesn't have a laser on it. Hmmm, I didn't even know that was an option. I'm glad to hear you are enjoying my videos! Let me know if there's anything specific that you're interested in me covering and I'll see if I can touch on it for you.
Yes you remove the large black cover from the top of the laser first then you adjust with an allen key on the side for side to side movement and the front top adjustment for angle. Bosch has a downloadable manual which covers this, but annoyingly only by pictures and no text.
@@oo0Spyder0oo thanks! I’ll try this on the weekend and let you know.
Howdy, have just done the adjustment - easy. The adjustment screws are accessible without removing the cover - although the manual says a 2mm hex driver, it’s a 2.5 mm. Not a big deal but as far as accuracy of info in the manual goes it’s a problem ie what else is not correct? Anyway, thanks for the help.
@@BorsellinoHomeServices I’ve got the 18V model so it’s probably just an extra feature on a different saw. However all the adjustments you made are still the same on my saw as for yours.
