Dewalt DWS780 | 12 inch double bevel sliding mitre saw
ฝัง
- เผยแพร่เมื่อ 13 ก.ย. 2024
- The Dewalt DWS780 is a 12 inch double bevel sliding mitre saw, the blade is 305mm or 12 inches. This sliding mitre saw has a 1675w motor and is powerful enough to cut the hardest timber. This mitre saw uses XPS technology to illuminate the blade, which creates a shadow directly where the blade will cut, this is much more accurate than a laser and will never require calibrating (unlike a laser). The Dewalt DWS780 has 5 speed settings, which means you can cut harder materials at slower speeds when required. The maximum cross cut at 90 degrees is 349mm, although by using a 38mm deep board you can cut up to 16.1 inches (409mm). This machine will cut through the hardest of timbers with ease and will give very accurate cuts when used by a skilled operator. You can find these machines for sale on ebay- fave.co/1mNntE1
I just got this for my dad. The look on his face when he opened his garage door. We’re here watching your video now. “Who’s your favorite now pop?”
WOW, your dad is very lucky ;-)
Thanks for the comment
Absolutely brilliant review. I have seen several videos on this exact saw and not one of them shows all the features that you do!
Thanks for taking the time to make it.

You are welcome
Thanks for the comment ;-)
This is the best review of this saw that I have seen! Thanks for taking the time to make it!
You are welcome.
Thanks for the comment ;-)
The best and most detailed review I have seen. I've been pondering getting one of these Dewalts (for $1,199.00 AUS including work stand in Australia) and your review has made the decision easier for me.
I'm glad the review is helpful ;-)
Thanks for the comment
I’ve watched many reviews and this is by far the best tutorial I’ve seen yet. Many thanks!
I'm glad the video helped
Thanks for the comment 👍
That was very clever really appreciate the effort to extend the cut and yes very helpful 👍😉
Glad it was helpful! 👍
Thank you so much for showing all the detailed features of this machine. Best, more thorough review of it yet & it features & how to use them. Saved me So much time so I can get to using so much faster. Love the tips too!
You are welcome.Thanks for the comment ;-)
Well done! I bought this saw today and the instructions are not the best, had to keep going back to figure things out. After watching this video I have no questions on how to do things. Those at dealt writhing the instruction manual should be made to watch this video. Thank you
+nsrvtqc Thanks, My Dewalt manual was pretty good but I had to sit down with a cup of tea and read it a couple of times LOLThanks for the comment
Great review, nice clear and simple walk through of the saw - thanks for posting. I have my saw being delivered this week, can't wait ! 👍
Glad it was helpful!
I'm sure you'll get lots of use from yours, this is a great saw ;-)
Great review... been using this saw for about 18 months and there are all kinds of features on this saw that I didn't know about until I saw this... I always wondered what those pawls were for!
I'm a beginner and used this to put hardwood floors in my house... the light that shows you the precise kerf of the blade made using the tool a lot easier.
Cuts like butter.
Absolutely.
Absolute brilliant 👍 had this saw for over a year. And learned 3 new things about it 😃
+MrEbby17
I'm really glad the video helped ;-)
I have been meaning to review it for ages, but never got around to it because my garage is so small and cluttered!
Thanks for the comment ;-)
Nice review. I bought this saw in part based on your review. Really happy with it. The light system really works great. My colleague has a Kapex with a laser, but I think this DeWalt makes finding the cutline easier.
Great to hear!
I love using this saw 👍
Good trick there with the board to extend the cut. I do something similar on my 254mm chopsaw, I made a base and back fence from some conti board off cuts, doing this allows me to use 210mm blades on the 254mm saw and still get a proper cut, great for me because I have some very fine tooth blades in 210mm from my old saw and they are great for cutting laminate flooring and other delicate materials, saves buying extra blades.
+caskwith
Thanks, how to do it was detailed in the instruction book that came with the machine. But it's always easier to understand when you see a video of how to do it, so I thought I would include it.
Thanks for the comment ;-)
This helped me out so much. Thank you.
I'm glad the video helped
Thanks for the comment 👍
That's a serious bit of kit. I do like De Walt tools , robust and fit for purpose
+JD Hammers
Absolutely, I have had most of my Dewalt cordless tools for over ten years with no problems.
My Dewalt 9 inch angle grinder is 16 years old and that only needed a new switch after lending it to someone that probably left it out in the rain!
Thanks for the comment ;-)
I have this model, purchased it a few months ago and I like its versatility, accuracy and ease of use and depth of cuts.
I am a bit annoyed at the fact that is does not come with essential accessories except for one vertical clamp.
The following accessories should come with the saw as standard and save the hassle of going out again and buying them. Would the manufacturer please take note, it may even help your future sales.
DW7082 Vertical Clamp (second clamp to save you from changing over each time).
DW7084 Crown Stops for the DW780 Mitre Saw x 2
DW7051 Length Stops for the DW780 Mitre Saw x 2
DW7080 Extension Kit for the DW780 Mitre Saw x 2
Cheers
I agree, more clamps would be useful.Thanks for the comment ;-)
I just got this saw and was doing the calibrations for tweaking up the miter and bevel angles.
For the bevel, I measured the angles by using the blade with a digital angle ruler. One span of the ruler on the base and the other span lined up against the blade. The 0, 22.5, & 45 degree left bevels were a bit off so I made the adjustments. I made sure that the ruler was totally flush against the blade and not on the side of a saw tooth.
Then when I did some practice cuts on real wood (2×4’s and MDF pieces), the angles were slightly off but extremely consistent. The 0 degree cut was off by 0.3 degrees, and the 22.5 and 45 by about the same. Noting the direction by which the bevel cut was either too shallow or deep, I tweaked the adjustments so that he actual cuts on wood gave 0, 22.5, and 45 degrees.
I made sure the ruler was zeroed out and calibrated throughout and made these measurements all a few times to make sure and check if they were consistent, and they were. I also used a 7” square to confirm the 0 degree cut on the wood - the cut was flush with the later empirical adjustment for the actual wood cut, whereas it was slightly off with the angle ruler 0 degree set on the blade.
Now when I measure the blade with the digital angle ruler, it is off by the amounts that the cuts were off before, which is what you would expect if things are consistent.
Question is: Why is there a difference between what is measured with the ruler calibration on the blade, vs. how it actually cuts? Does the high RPM on the blade change the blade aspect or something? Does the force between the blade and the wood change the blade aspect?
I'm not sure to be honest, but it's a great piece of kit for the work I do.
Thanks for the comment
I don't think anyone will be able to tell you exactly what the problem is because its going to require trial and error to find the inaccuracy. My two cents:
1. One of the measuring instruments is not accurate. I actually find this to be fairly common especially among newer tools. Basically the new affordable tools we all reach for often aren't built to the standards we would expect. In most circumstances it isn't noticed but when it comes to accurate angles it becomes evident.
2. The blade might have a slight wobble, be loose, or off center slightly.
3. The arm or sliding operation of the machine may be defective. Ive heard the type 20 motor of the dws 780 has horrible problems with the sliding feature, so much so that many users return it immediately. So this proves Dewalt quality control isn't perfect.
4. The surface you are measuring may be true but the extended surface where the material rests might have a rise or depression that is unmeasured by the short protractor, and in turn results in a bad line when placed on the table.
I took my measuring devices to work to have them double checked for accuracy. We have a machinist shop with known accuracy. I found one of my squares was off more than I would like, another was was accurate to within .002" So that could be an option for you. Find a friendly machinist shop to allow you to double check your devices. Good luck.
looks a great saw. I have the same evolution saw that you sometimes use, which I love. But I really like the versatility of this Dewalt saw to cut mitres without needing to lay the workpiece flat and tilt the blade. Another great review video. Happy new year!
+David Jarrold
Thanks David, Happy new year!
This machine is very good for long, accurate cuts. I originally bought it when I was making a sandpit for the kids - th-cam.com/video/M-r8AA-bpE4/w-d-xo.html
I told the girlfriend I needed it to cut the sleepers, but never cut them in the end ;-)
She fell for it, hook, line and sinker LOL
Thanks for the comment
Thanks for sharing tip. I just bought this Mitre Saw and I learned quite a bit.
You are welcome.
Thanks for the comment
Great review and really useful for new owners.
TH-cam at its best!
Many thanks.
You are welcome.
Thanks for the comment ;-)
Great review! Just enough detail and right to the point. Thanks for posting it. Have one on the way.
+kendawg833 Thanks for the comment ;-)
Nice video. Well done.
Thanks for the comment 👍
only one little thing you missed out. It is possible to go beyond the 49 degree on bevel cut. For xample, if you tilt the sawhead to the right you push or pull a lever almost at the bottom below the locking wheel on the left side of the bottom. And vice verse if you tilt the machine to the left. Then you are able to do even greater angles than 49 degree bevel cuts.
Thanks for the info ;- )
Brilliant video. Thanks for making such a detailed review of this saw.
You are welcome.
Thanks for the comment
Vou sim comprar uma dessa !Deus vai mim ajudar 🤗💕
Well done mate on your demonstration this has helped me big time thank you 👍
I'm glad the video helped
Thanks for the comment 👍
Very decent and informative tutorial. You deserve Likes, Subscriptions and 5 Stars.
+DRAGON TOUCH
Thanks very much ;-)
Thank you for posting such a good review. It is immensely helpful!
You are welcome
Thanks for the comment 👍
Dewalt still make the best mitre saws on the market I have a 12 year old dewalt DW708 that is in almost daily use and has been well abused. I love it and will replace it with a dewalt if it ever dies. I'm by no way a dewalt fan boy and actually don't rate a lot of there newer tools but the mitre saws are the best in the business. They would kick the arse on a Festool kapex.
+Adam Lynch
Thanks Adam, I have always been impressed with mine but you still get some people saying they are not as good as some other brands. I'm sure some of these people have not tried the Dewalt though and are just surmising.
Thanks for the comment
Great detailed review, thank you. :)
Glad it was helpful!
👍
Best review of this saw
Thanks for the comment, Peter ;-)
I just bought the machine, thanks for that excellent video!
You are welcome, this is a fantastic machine ;-)
Thanks for the comment 👍
Good review , thanks
You are welcome
Thanks for the comment 👍
I have this same saw... but the North American version. I have to disagree with you on the Lazer though. I have had mine for 4 years and i have never had to readjust mine. Its still perfect.
+Drew Willcock
I didn't realise Dewalt used a laser on their mitre saws, most of the mitre saws that I have seen have a laser that can be adjusted if it goes out of alignment.
Thanks for the comment
Very good and detailed video
+Junior J
Thanks for the comment ;-)
Nice video as usual.
Great machine that one.
I have the old DW710 type 1.
+Rui Nunes
Thanks, I think that is the model that my mate has- which made me buy this one!
Thanks for the comment ;-)
6 years on, do you still have/use this saw? Doesn’t seem to have changed much so it must be a case of stick to a good thing.
Yes, I still use this for larger jobs. I used it just a few weeks back to cut some sleepers to length. It’s a great saw 👍
@@ultimatehandyman Thank you, might be my next purchase then! Cheers
Excellent review pal
i have just today bought a 12" SIP dual bevel, its sat in my kitchen unopened in its box and after seeing this review
its staying in its box:) and going back
this thing looks in a different league
how accurate is it for cutting 45s for large skirting, architrave, etc
thanks for sharing
Its been very accurate on all the mitre cuts that I have done, it really is a cracking saw (even if a little expensive).
Thanks for the comment
I have a 12 inch SIP and it’s absolutely rubbish. The accuracy is never The same two day running. The laser is totally unuseable as you cannot see it. Would avoid SIP tools at all costs.
Fantastic and super helpful!
Thanks for the comment ;-)
Great review. What blade and number of teeth are you using to get such a good cut? Thanks
Thanks, it is just the standard blade that came with the machine, which I believe is this one- bit.ly/3Rgu3BI
👍
Great review, can i ask what is the deepest skirting you can cut on it, with the skirting vertical and a 45 degree cut ? thanks
170mm is the depth of cut, but obviously if you lie the skirting down flat and use the bevel cut, you can cut virtually any size of skirting
Good video sir
Thanks for the comment 👍
Great Review, you definitely covered all bases. Is that the 60 tooth stock blade you're using that came with the saw? If so, how do you rate it? I'm seriously contemplating purchasing the DWS780 and DE7023 leg stand in the next few weeks but was wondering whether to purchase an additional blade as many manufacturers seem to ship their saws with inferior stock blades. I could wait and see for myself but thought I'd ask for your opinion!
+Peter Firth
Thanks Peter, Yes as far as I'm aware it just comes with a stock blade on the machine. I mainly use mine for decking etc. so the finish is not critical on the work that I do. A better blade would probably be needed for fine carpentry etc.
Thanks for the comment ;-)
Hi, i have been searching the internet and found that a 12” miter saw could not do a 45 degree miter cut on a 4x4. Is that true?
Hi there, I have a evolution mitre saw, not accurate at all, how accurate is this machine? is the fence dead straight one side to the other, if at 90 degrees out , can be be put accurate 100%? thanks in advance
Yes, the fence is dead straight.
Have you tried adjusting the evolution?
Sometimes they get knocked during transit and need adjusting before they are accurate.
Obviously the Dewalt is the better saw for cutting wood, but it is much more expensive.
Great review, just bought one myself.ive noticed it has the safety switch below the trigger just like yours,but I can't see any online that also have this, is this the norm? I find it a bit fiddly!! Also noticed my disc didn't have the yellow around the tip like many online and I thought it might be a fake or something stupid but yours is also the same so that's kinda reassured me :)
Oddly enough I used mine today and also thought it was fiddly, I'm sure this is the norm.it's a great saw ;-)
Thanks for the comment
I want to ask an important question if you can help me please. How the accuracy of this machine angels and the indicators, dose it has big tolerance in parts?
+Hassan Nono This machine is normally very accurate. I have not known it to be un-accurate when I have been using it although it would depend on exactly what you are cutting with it. Thanks for the comment ;-)
Good review !
Thanks for the comment ;-)
I'm about to upgrade my rage3 and get the dewalt 774. I know what I would use 45 and 90 deg cuts for, but what are the other common fixed angles usually used for eg 22.5 degrees, that are marked on the saw
I think they are used when installing cornice or crown mouldings etc.
Thanks for the comment
@@ultimatehandyman thanks for the reply !
What about ripping down large boards or panels?
+camohoj
You can't do that on any chop/mitre saw that I am aware of.
Thanks for the comment
Table Saw, Vertical panel saw.
Miter saws are not meant for wide panels and sheet goods.
Yes but your sandpit is someone else's Tracy Island 👍😄🇬🇧🍰💪🤘😎
+wayne burgess
Ha Ha ;-)
Can you lower the rpm to a speed that will cut metal like 2000 - 2500 rpm? with the speed selector?
I'm not sure what the RPM is when using the speed selector, I only know that 5 is the fastest and 1 is the slowest.
I think you can get a blade for cutting aluminium for this machine, but don't think any other metal cutting blades are available for it.
I have the 707. I don't find it that accurate for mitres. I guess this one might be more precise. Shame it doesn't have an electronic brake.
+SLRist
It has an "automatic" brake (whatever that is), but it is very slow at breaking. I have seen some saws with very fast breaks, which is an advantage if you want to use it safely and quickly.
Thanks for the comment ;-)
No longer has five speeds.
Nice
Great review, saw instructions in box tell you nothing in comparison to this review.
Thanks for the comment
have you got any makita gear
+Funky Farmer I have a Makita laser level and also a Makita core drill. Makita are just too expensive for me and from what I have heard from some people they are not as good as expected. Most of my cordless Dewalt gear is over 10 years old and still going strong, the only time anything has gone faulty is when I have lent them out.Thanks for the comment
my mate just got one of these nice saw but bevel cut is not as good as the old saw blade cover get stuck on wood arm that moves up is rubbish
Thanks for the comment ;-)
Dear Santa 👍😄🇬🇧🍰💪🤘😎
+wayne burgess
Ha Ha, it's a cracking piece of kit ;-)
I told the girlfriend I needed it when I was building the kids sand pit LOL
this aint the xps model is this the older model
This is the DWS780, it has XPS on it- as far as I am aware the XPS is just the LED light, which casts a shadow of the blade onto the work piece.
Thanks for the comment 👍
I did had a two of this one get stolen other i sold nearly new for half price! Its no good for fine work! good for row work fences, decks, roofs etc.
NO GOOD FOR FINISHING JOINERY /CARPENTERY!!!!
Thanks, very good review
You are welcome.
