If you haven't considered trying a circular saw blade on a table saw, I recommend trying it. A circular saw blade has a lot of advantages over traditional 10" table saw blades. A 7-1/4" circular saw blade can be used effectively on most table saws with the exception of a SawStop.
My go-to 10" blades are the forest woodworker II amzn.to/3j7YiJU and the Freud Industrial laminate blade: amzn.to/34vaz7g

By adding this inexpensive new 7.25" circular saw blade to my table saw I was able to:
- double the power of my saw
- improve cut quality
- decrease dust generation
- reduce sound output
- improve safety
The difference in cut quality is dramatic. The circular saw blade on a table saw produces cut quality that is like glass. It's actually nicer than I get off of my jointer. Try a smaller circular saw blade on your table saw and let me know what you think! - แนวปฏิบัติและการใช้ชีวิต

CLARIFICATION. My apologies; I misspoke on one point made in the video when I said that the smaller blade would deliver more torque. In reality, torque is a constant in this scenario, as it is a measurement of rotational power delivered from the center of the arbor. Torque = force multiplied by distance. So, with constant torque the smaller blade delivers greater cutting force because of the shorter distance. The power advantage that I was explaining is accurate, but I should have referred to greater cutting force rather than greater torque.
Inversely proportional to the distance, right?
Cutting power is inversely proportional to cutting diameter, yes.
@@ToolMetrix Does the fact that the 10 inch teeth are moving much faster than the 7 inch teeth factor into this at all?
Yes it does. It makes it safer and quieter to cut with the smaller blade. It also in theory would slow down the rate at which you can feed stock although the other variables that come into play that determine feed rate would include HP of the saw, kerf size, tooth count, etc.
Genius ! I have been looking for a couple of new table saw days , all costing a lot more. You just saved me money. Thanks
Thanks for your feedback! Glad that it helped. Cheers, Paul
Thank you for your advice. Just put the blade on, and I love it!! Really smooth cuts, quiet and less sawdust.(and the price!!wow!!) Thanks
Thanks for sharing your experience! Glad it worked well for you. Cheers, Paul
Super interesting notion, I am willing to give it a try. The cost would also be an interesting variable
Let me know how it goes. Cheers
I have heard this several times now and will definitely use it with my new saw. Thanks for the info breakdown, have not heard some of the info you provided. I work primarily with reclaimed wood and this will definitely help should I miss any foreign objects. Thanks again 👍
Thanks for the feedback, Terry. Great point about working with reclaimed.
Thank you. I never thought of that and your arguments sound logical.
Thanks for your feedback, Richard. Cheers, Paul
Only issue is that the smaller blade might not have enough height to work with the bunch of custom jigs that every woodworker have. For non-jig usage though, this absolutely makes a lot of sense. Thanks for the info.
Good point. Maybe an 8” blade would work better for that, and still provide some of the benefits of a smaller blade.
I did this as you recommended, I can't believe that I never thought of this 30 years ago. It works just as well as you said. I hardly ever work with anything but 3/4 material. Thanks!
Thanks for the feedback, Gary. Glad that you had the same great experience. Cheers, Paul
I've never had the thought of using a smaller diameter blade on my saw but I think it's a pretty good idea. Definitely going to give this a try.
Sounds good Jim. Let me know how it goes for you.
Really helpful for me. I'm an artist and cut a lot of 1/8" and 1/4" tempered Masonite. I used to run a 6" blade on my 7 1/4" circular saw.
The only reason, was my small town hardware store was out of 7 1/4" blades. It worked really well. I'll def be putting a 7 1/4" blade on my 10" stationary table saw.
Surprised I didn't think of this. Thanks!
Thanks for the feedback and for sharing your experience, August. Cheers, Paul
You are right. I often used my Freud Diablo 7 1/4 blade on my 10" table saw, it works great for miters and 45 degrees rip cut.
Thanks, Bobby. Great to know!
I have used 71/4" Diablo saw blades,in mi sears table saw and I staked 3 of them to make grooves, With excellent results.Great video, thanks.
Thanks for sharing your experience with us, Sady. Cheers, Paul
Definitely gonna give this a try. Very informative vid. Thanx.
Thanks James. Let me know what you think. Cheers, Paul
Amazing video! Going to try it as soon as the poly dries. Thanks!
Awesome! Let me know what you think.
Paul, thanks again. I had to go down to HD anyway for a couple of Bessey clamps I had ordered. I picked up a 7-1/4” 40 tooth as well as a 60 tooth Diablo. I popped the 40 tooth in my tablesaw. Then I made some cuts on three-quarter inch Baltic Birch as well as three-quarter inch MDF. I also made cuts on 1“ nominal Maple as well as Red Oak. Like butter! And the cuts are very clean. I did rip cuts in the hardwoods. I haven’t tried out the 60 tooth yet on my plywood but I’m sure it will be even a little smoother. Although I now have some overhead dust collection on my tablesaw, MDF is still dirty stuff. I’ve been using a thin kerf 80 tooth Freud blade (.093” is better than .125” for sawdust) but the .062” kerf of the 7-1/4” Diablo is better still! I always thought of Diablo as the “lower tier line“ of Freud. But I have to tell you there is nothing lower tier about these blades. Great recommendation!
GREAT feedback! Thanks for sharing your test results, Steven.
Point well taken. Makes sense to me. You did a great job of laying out your argument. I have two saws on my work flow and I am going to change one of the blades to a 7 .25 blade and diablo is one product
Thanks for the feedback, Ronald. Let me know how it works for you. Cheers, Paul
Thank you very much!!! I got the blade and yes is fantastic how glue ready the cuts are!!
Awesome! Thanks for sharing your feedback with us. Cheers 🍻
makes sense definitely gonna try this. I use those blades all the time. Im a contractor not a woodworker. My table saw is a Bosch Jobsite saw
Thanks for the feedback, Don. Should work great on that saw. I tried smaller blades on a Dewalt jobsite saw and it improved the performance and cut quality.
How on earth did I miss this post for over a year plus? First of all, your analysis of the 7.25" blade on a full size saw is complete and well thought out. The logic is sound and like you stated, unless you are going to cut thick material, your downside using the small diameter blade is greatly outweighed by the benefits. Excellent video and subject matter ... my eyes are now wide open to the possibilities. Thanks for sharing your findings ... I for one feel fortunate because of your efforts. Cheers Mate!!
Hi Dave, thanks for watching and sharing your feedback sir. Cheers, Paul
This is a GREAT idea for most of the work I do!!!!!! Why has nobody ever mentioned this??????? On my way to the store tomorrow!!!! Thank you!!!!!!!!!!!!!!!
Thanks Brian. Let me know how it works for you. Cheers, Paul
Simple idea. Brilliant. Thanks for sharing.
Thanks Reid.
Man what a great idea! How have i not known about this before now! I cant wait to try it on my Dewalt contractor saw. Thanks for the video
It’ll work great on that saw. Good luck 👍🍀
I HAVE ALWAYS WONDERED THIS. Thank you man this is amazing
Awesome. Thanks for the feedback Truman. Cheers.
Thanks I'm cutting some thicker slabs of Purple Heart and this idea will definitely be of a benefit I believe 👍
Thanks Kevin. I’d love to hear how it works on something as dense as Purple Heart. Cheers, Paul
Tried it on a bunch of 5/4 pine I had to rip into small strips. Worked beautifully on my little 8.25” DeWalt portable table saw. Thanks!
Awesome! Thanks for sharing your experience here, Richard. Cheers, Paul
Great info! I just made up some throat plate blanks and I'm going to save one for use with my new smaller blade when it comes!
Hi Eileen, thanks for watching and sharing your feedback 🙏. Cheers, Paul
GREAT Video! I'm going to try it.
Thanks Ted. I appreciate your feedback. Cheers, Paul
Thanks, I'm definitely doing this.
Thanks for the feedback!
After seeing this I installed a $14. DEWALT DWA181424 8-1/4-Inch 24-Tooth Circular Saw Blade on my table saw just to reduce the dust. It really works!!!! and will cut 2-3/8"
Awesome! Thanks for sharing your experience, Metal. Cheers, Paul
Excellent points. Thank you!
Thanks for watching 🙏
I agree with all that you have said. I’ve been doing this for many years and have been happy. The cost isn’t much of a factor when you take your used saw blade in to be sharpened. there’s not much cost difference. I would like to add one thing. With the torque of the smaller blade, you don’t have to push as hard minimizing slipping and binding.
Great point! Thanks for sharing this, Jeff. Cheers, Paul
What a coincidence! About 3 years ago I put the 6½" blade from my cordless saw on my Grizzly cabinet saw. Being a mechanical engineer I came to the same conclusions as you did as to up/down side. I use the smaller blade exclusively for cutting ply wood or melamine. Silky smooth. There is one additional upside: It's a LOT easier to make the initial cut on a zero clearance insert. In fact, I have made a second cut in all my other zero clearance inserts so I just flip the insert 180° between 10 and 6½" diameters. Thanks.
Hi Wilhelm, great minds think alike! And, I love the idea of the double duty zero clearance insert. I’m gonna do that for sure! Thanks, sir. Cheers, Paul
Great video! Thanks so much
Thanks for your feedback, Aaron! Cheers, Paul
I agree. I've been running 7-1/4" x 1/16" inch blades for years. Not very often do I need a bigger blade but, when I do I just swap it out for a 10" then swap it back.
That’s great. Thanks for sharing your experience here, Tim. Cheers, Paul
I had been using blades by Irwin, Dewalt, Kobalt, etc. Then about 5 years ago I started hearing how great the Freud Diablo blades are so, I bought the 10" general purpose blade for my table saw. Boy, what a difference!! I love it so much I went and bought more blades for the miter saw and my two circular saws. I'm pretty frugal and went and spent the $40 for that ten-inch blade, but now hearing you say you are using the 7-1/4" on your ten-inch table saw is great! I'm going to order two more of the thin kerfs, one for ripping and one for cross-cutting. That will only be about $27 as opposed to $80-$100.00 for the 10" versions. Thank you for sharing this with us!
Great plan. Let me know what you think.
what a good idea, thank you
Thanks for watching, Jack. Cheers, Paul
I use the Freud glue line rip blade and it works very well but this is less than sharpening so I am going to give it a go. The added performance and yield is very appealing also - thanks for the heads up!
Awesome. Let me know what you think. Paul
Thanks for the tip. I am definitely going to try a smaller thinner blade. HD has these in stock.
Awesome. Just be sure to get the right arbor size for your table saw.
Great video! I had an “aha moment”. I switched to a thin kerf plywood blade on my saw stop and I could not figure out why I felt binding. It’s the riving knife! Thank you for a great video.
Thanks for watching, Stephen. Yep, that riving knife will getcha. :) Check out Shark Guard; they can make a thinner one for you.
I always have great luck with the Diablo blades...I'll definitely look for this one too
Yep, agree. great quality and value brand.
WOW! I just tried it! Had a 40t Freud kicking around. Cuts like "butta"! Thanks for the tip!
Awesome. Thanks for sharing your feedback. Cheers, Paul
Great tip! Thank you!
Thanks, Tammy!
Thanks for your nice info-clip and yes, I have a few of the Harbor Freight blades which I did
purchase for being affordable and now I have learned about other advantages - take care!
Awesome. Thanks for watching!
First time Ive heard of this. Very smart
Thanks Octavio! 🙏
Great video and eye opener. Thanks
Thanks for watching!
Great tip, thanks
Thanks for the feedback Alonzo. Cheers, Paul
I've been using a 7 1/4 blade for about 6 months now and love it. Great results and I do feel safer using it. I'm looking into getting the shark guard for my older Grizzly 3HP table saw. Thanks for the video!
Awesome Blair. Thank you for your feedback. Cheers, Paul
Very interesting I have the same cabinet saw I will give it a try.
Awesome. Let me know what you think.
WoW it work so well Thank's
Awesome! Thanks for sharing your experience, Denis. Cheers, Paul
Thank you for overstating the obvious, you are the only woodworker to figure this out, BRILIANT! Thank you.
Thanks Manny.
Wow. Great info. Thnx
Thanks for watching, Tim. Glad it was helpful.
Killer info!! Thanks! My 5hp PM 2000 thinks its on vacation......
just jim
Ha! That’s a great way to put it. Thanks Jim.
I'm in the infant stages of wood working. I'm learning how things work. Seeing your video I hadn't even thought about blades most of my work is small pinterest things for the wife. I can't wait to try this. I for sure see the uneven cuts on small rips. Thought it was just me.Thanks
Thanks for the comment Gene. Welcome to the world of woodworking! Cheers, Paul
just stick with 10" full kerf freuds/ridge carbides and leave these dremel sawblades for kumiko enthusiasts
Good suggestion
I bought a Mikita track saw last year and was blown away with the quality of the cut it produced using a tiny 6.5” blade. Eventually I grabbed a fine finish diablo in 6.5” from HD and put it on my table saw just to see if it would do the same. I was blown away with the improvement across the board. I now only use a 10” blade when I need the rip capacity. An additional safety advantage that I have found is that the length of blade exposed above the table is shorter with a smaller diameter blade which reduces the injury potential when doing small “danger close” cuts where the blade guard might not be accommodated. I have found that the thinner blade is more susceptible to wandering during a cut so it is important to have the saw tuned extremely well and use guides or feather boards whenever possible.
Great points, Paul. Thanks for sharing your thoughts. Cheers, Paul
Simple but excellent.
Thanks John.
Very cool idea!
Thanks, Nate! Cheers, sir.
That’s a great idea ! Thanks . John
Thanks John. Cheers, Paul
@@ToolMetrix the only downside is I can’t get that blade in the UK 😬
I've been using Vermont American (7.25" & 10") Laser X2 blades on my tablesaw & circular saws for over 20 years.
They have "V" shaped cutting tips so they are self scoring on both sides of the kerf.
These are full kerf blades btw. I also do use blade stabilizers on my tablesaw with the 10" blades.
I will give the thin kerf Diablo blade a try for comparison. I think the prices will be pretty much the same. Good data/video.
Thanks, Mike. The V shape sounds interesting, and I can see some advantages to full kerf in some woods that would put more pressure on the blade to flex. Cheers, Paul
That's an eye opener great tip
Thanks for the feedback Gary!
Thanks for information
My pleasure. Thanks for watching, Andre.
I was just about to replace my 10 inch on my shop saw and stumbled upon your video. Everything you explained makes perfect sense. I'm going to buy that Diablo blade and try it this week.Thanks for taking the time to make your videos!
Thanks Jeffrey. Let me know what you think.
Thanks!
My pleasure Keith. Thanks for watching.
Always had those good experiences working with smaller blades , making drawers is one example.
Great feedback. Thanks 🙏
I just bought my first table saw and had no idea I could use a 7 1/4 blade on a 10' saw. I actually already have that 7 1/4 diablo on my miter and I think I paid 12 or 13$ on Amazon. I'm glad I came across this video definitely going to try the blade. Thanks for the info.
Thanks for the feedback Brian. Let me know what you think.
@@ToolMetrix Well it wasn't a good first try but that's my own fault. Like a dummy I put the 7 1/4 in not thinking about the cuts I needed to make. I was more concerned about the noise and sawdust because I live in a condo with a connected 4 car garage and my 1 neighbor hates me, she's a drunk and a miserable old lady I've never seen her smile I don't even know if she has teeth. So she complains to the association every week. Like I said I was thinking about her and not the cut. I was cutting some dados and the smaller blade was taking forever so after the second I put the 10 back on and haven't used it since. Tomorrow I'm gonna try it again. No I don't have a Dado blade. I've already spent a ridiculous amount of money this year tooling up. The end of last year all my tools got stolen out of my car, basically my whole lifes collection. I started fresh, which sucked money wise but was awesome tool wise lol. I love new tools. I'm working on a bench with my table saw, miter shop vac dust collection and everything else built in but it's tough because space is very limited. I made a soundproof box for the shop vac and table saw. Obviously it's not fully soundproof but I hope it works I'll find out tomorrow. It would be impressive if I could soundproof the saw and still make cuts. I'd be the next billionaire. Sorry went way off topic. I'll keep you posted, hope to see some new videos. Oh question is there a way to power a table saw on and off using a power strip? I want the vac and saw to go on at the same time. I know they have power supplies that do that but I'm trying not to spend any more money. I can turn the vac on but I have to still turn the saw on from it's power switch. I have a push button power supply but I don't know how to get the saw hooked up to it. It's actually for your foot step on the button for power.
I've often thought about the same thing but never took the time to try it. Glad to see that you have, I'll definitely give this a try on my unisaw. One thing to consider though is that the smaller blades don't have the same variety of tooth shapes but maybe that won't be as much of a factor as we think.
Hi Bruce, There are actually a pretty good variety of tooth configurations available on the 7-1/4" blades. I find that the one that I use provides a good combination of feed rate and cut quality. If I were mostly cutting sheet goods I would definitely use a blade with a higher tooth count. Cheers, Paul
@@ToolMetrix thanks for the reply back, I'll seak out some different tooth profiles.
Bruce
You sold me. Great idea. I just ordered a 7.25 blade.
Awesome Bill. Hope you love it!
Thanks for the video. I have gone to 7 1/4 blades and using a vibration dampener, with a 16th thickness, and have experienced exactly what you said. I agree.
Awesome! Thanks for the feedback. Cheers, Paul
Thanks. Never considered doing this.
Thanks for your feedback, George. Cheers, Paul
I was Googling for a new tablesaw blade when I came across your video and am very glad I did. I live in Thailand where everything is in lockdown just now because of covid and the choice is pretty dismal online for 10 or 12 inch blades. Now I shall go for a 7 inch choice which seem to be much more plentiful. Thanks for the great info.
My pleasure. Thanks for the feedback and let me know how it goes for you. Cheers, Paul
@@ToolMetrix Hi Paul. Well I ended up with an 8" blade as the 7" would not fit my arbor. You were spot on with all your comments and it cuts beautifully clean and does thin cuts great. One big problem, which you covered, is the splitter, which causes the wood to bind when I get 3 or 4 inches past the end of the blade. Not sure what I will do about that yet as I don't have your resources or contacts but I will hopefully come up with something. Any ideas you may have would be most welcome. Thanks.
You can easily make one out of a piece of aluminum. Just cut in on a bandsaw or maybe even a scroll saw. Or go with a shark guard like I did. Very awesome.
@@ToolMetrix Thanks for the suggestions. I'm sure I can find something to do the job. Just finished a rocking chair project so having a couple of days off but will come up with something when I get back in there.
Totally agree with you. I have not tried the Freud smaller blades, but I use the Irwin Marathons. They work great and are reasonably priced. Not for everything, but for rip cuts these 7 1/4" blades are tops.
Good feedback. Thanks 🙏
I completely concur. I use a 7-1/4" thin kerf on my 10" table saw all the time unless I need a deeper cut, then I use a 10" blade 👍
Thanks for sharing your experience here. Cheers
I started using dewalt 40 tooth on my dewalt contractor saw it ripped 2x4 I found it way easier on the motor.cut was awesome. Had very little chipping on melamine.
Great feedback. Thanks Randy!
I honestly can't wait to try this.
Awesome! Lemme know what you think.
@@ToolMetrix I was trying to find the exact same blade that you were using(Model: D0740A) but I could only find (Model: D0740R) locally. For me, these blade are around 30 dollars Canadian. I am wondering if there is any discernable difference.
Btw, thank you for the video. Your explanation was fantastic.
I did this on my 8.5 inch Milwaukee contractors saw. Number one it is battery powered and I find the battery lasting somewhat longer, and two whwn I shut the saw off it stops immediately. It stopped quickley before, but almost instantly now. Thanks. Using 7.25 blade now.
Wow, that's great feedback. Hadn't thought of the battery benefit, but makes sense that it would made a significant difference, as well as the faster blade stopping. Thanks for sharing. Cheers, Paul
Yea. This works. I subscribed.
Thank you, Paul. Cheers, Paul
I have been using that exact blade on my saw for many years and it makes the best cuts of all the blades I have tried. I also have a 81/4 and a 10 in blade in case I need a deeper cut. But nothing cuts as smooth as the 71/4 40 tooth red blade.
Thanks for sharing your experience here, Richard. Cheers sir.
Very Interesting, never thought to try this, but I will now. Combine this idea/philosophy with running a proper blade type (ripping, crosscutting, laminate etc) for cuts and 95% of my tablesaw activity could be done with more efficiency and result in cleaner cuts at a substantially lower price then my ridge carbide and diablo favorite blades. Only catch I can come up with is the cutting depth may not be sufficient for some sled or jigs use (?) new riving knife needed in most cases ... time to test .. excellent idea, thanks.
Yep, all true. An 8” blade would still have many of the benefits and still work with some of the jigs.
The 7 1/4" blades work well. I think it was a great idea to have Shark Guard make you an appropriate splitter to use with them.
While it makes sense that the small inexpensive blade is a good solution for you, I suspect your saw may have more runout than it should, causing problems with the WWII. If the bearings are good, it might be worth checking (and correcting) the arbor flange.
Thanks Alan. I appreciate the feedback and the suggestions. Cheers, Paul
yes, the weight of the WWII on a bad arbor makes it squirrelly
As a DIYer I thought about this but always though there must be a good reason why professionals don't use a 7.25" blade even for these smaller cuts. Thank you for the tip, I will definitely give this a try.
Great! Thanks for the feedback. Cheers, Paul
Many pros have a Sawstop - and you cannot use a smaller size blade on a Sawstop. The brake will not work
Yep, that’s a sad but true story.
Many professionals don’t have the time to keep swapping out blades for each cut.
Thanks for your comment, Jon. Definitely. If you would have to swap for each cut then this is definitely not a good approach for you, whether you are a hobbyist or a professional. It’s not for everyone but many professionals do use this approach. It really depends on what material you normally work with. If this worked for everyone in all situations then 10” blades wouldn’t exist. 😀
Great helpful info.Do you have a address for Shop Guard? Also I appreciate that you don’t have loud music during your video. And you speak clearly and with good volume. Thanks for sharing your knowledge. PBW
Hi Paul, thanks for your feedback. All I have is a web address. Here you go: www.thesharkguard.com/
never considered a smaller blade, thanks for the tip
Thanks for watching
Consider trying the DeWalt 7-1/4" 60T Ultra Fine Finish Blade (DW7116PT). For me, it provides very clean crosscuts and rips in plywood (with good face up on table saw), and it glides through hardwoods with only a .063" kerf . . . very little cut resistance. I gave it a try a few years back and it's still on the saw.
Great suggestion. Thanks! 🙏
Try increasing the size of the pulley on the motor. Now you have something.
I make buttons so every single cut is thin, either 1/8 thick strips or 1/4 inch thick strips and its often rare exotics like rosewood, ebony, kingwood etc so the savings in wood alone will be worth the switch. I hope the edges are as smooth as described because that will represent a lot less time at the sander.
Let me know if it works out for you. Seems like a great fit.
Wish I had switched to a smaller blade on my table saw earlier. What a difference! It changed my table saw from heavy metal to smooth jazz, plus all other benefits. You can only enjoy it after making the switch. Couldn't be more happier. Thanks.
That’s a great analogy! Thanks 🙏
This is an interesting video. I hope lots of people see it. I've used circ saw blades on the table saw for years, but almost exclusively when I needed the ultra-thin kerf. I observed that the cut quality was better than I initially expected, but I never thought to compare it to my dedicated rip blades. It doesn't surprise me that it's better than the WWII. I never thought much of the ripping performance of that balde. It's fine, and I rip with mine all the time, but if I need a really clean rip, I swap it for a 24T raker blade. However, your explanation of why the rip quality is so good is really insightful and makes a lot of sense.
I'm skeptical of your kick-back advantage, though. Tooth speed doesn't determine the speed that the object is kicked back. It does establish the upper limit, but the actual speed of a kicked back board is going to be much lower than the tooth speed. The energy transferred to the board will be equal to the force applied multiplied by the time the tooth is in contact with the board. The speed of the board will be the square root of the energy divided by the mass of the board. The mass of the board is fixed. The time the tooth is in contact will be mostly determined by the conditions of the kick-back. (Notice that a large board jammed between the blade and the fence will often kick back with a lot of speed, while little cut-offs bounce off the back edge of the blade with much less speed. That's because the contact time is so short for the cut-offs because they're so easily moved out of the way of the blade.) If anything, I think the slower tooth speed might result in a board remaining in contact with the blade slightly longer, but my hunch is it hardly makes any difference. So if we assume the mass is fixed, and the contact time is based on conditions rather than blade geometry, then the speed will increase in proportion to the square root of the force. As you pointed out in your comment, the force applied at the tooth of the smaller blade is greater, so the kick-back may be worse.
I say may be, because even that is an oversimplification. For example, when that sudden contact is made it's going to tend to slow the blade down. A thick 10" blade is going to have more angular momentum than a thin 7" blade, but how much difference that makes will depend on your saw. On a cheap, job-site saw with a 15A universal motor, the arbor and motor armature won't contribute as much to the angular momentum of the system as it will on a cabinet saw with a 3HP induction motor. I can think of several other factors likely to contribute as well, although to a lesser extent. I don't know if one blade size is safer than the other, but I know it's too complicated to trust our intuition.
That may sound a knit-picky, but you're clearly a smart guy who put a lot of thought into this. I thought you might appreciate another way of looking at it.
Thanks for watching and sharing your insights here.
very interesting proposition. I am new to the table saw game and I could use more cutting power for my Delta hybrid saw. Thanks!
Hi Faruk, thanks for watching and for sharing your feedback. If you try this on your Delta saw, let me know what you think about the boost in power. Cheers, Paul
Excellent points I guess the only downside is that you cannot use arriving knife since it'll be too thick and you would have to replace the blades a lot sooner since there's less teeth but again they're cheaper so that's that.
Thanks, Martin. Great point about the riving knife. The one that was made for me by Shark Guard works great. Perfect solution. They can make one for just about any saw.
Great video!
Some useful math for you: SFPM (Surface Feet Per Minute) x 3.82/ Diameter = RPM RPM x .262 x Diameter = SFPM As you can see, there's a huge difference in surface speed between the 7.25" and 10" blade.
Thanks
I never thought about trying this. I switched from a 1960s Unisaw to a jobsite saw and I will definitely try this for cutting plywood. My only concern is that the riving knife will not be as effective.
You will likely need a thinner riving knife.
We only buy the 7-1/4" X 24 Tooth Framing/Deconstruction blades. I'll start using the proper 7 1/4 Diablo blades in my wood shop. Thanks
See which one you like better. There are trade offs.
Thanks and I will try the blade for myself soon. Ordering the 40T and a Diablo 60T fine cut blade. I wondered if you have tried the 60T blade.
Sounds great, Walter. I have a 60T on my circular saw but haven’t tried it on my table saw. Let me know what you think. Cheers, Paul
Wow, really a great idea which I will put into place. Also, in an earlier comment regarding the Laguna table saw, I am a proud new owner of the Laguna Fusion3, thanks to you. But, do you know if there is a slider accessory available for Laguna saws?
Thanks Scott. I’m not aware of a slider accessory directly from Laguna. Maybe there’s a third party option?
⭐⭐⭐⭐⭐ Magnífico !!
Thank you!
This is really great insight for using a smaller blade. At the time of this writing I see you have 17 dislikes (thumbs down), are they crazy! The Debbie downers must be the manufactures of the 10 in blades. You are totally correct in what you say. Thank you/
Ha! Thanks, John. TH-cam is a humbling environment. :)
There’s nothing controversial here. This has been well known and accepted by many luthiers and trim carpenters for years. I’m sorry that this difficult to accept.
@@ben68442 So I realize I may have offended some using the word "Crazy" and for that I sincerely apologize. The planform should be used to constructively exchange Ideas.
Now you tell me! I switched over a while ago. Another plus is that when you shut the power off there is less free wheeling of the blade and it stops sooner which = SAFETY!
Great point - Thanks for chiming in!
Good Info.As far as Kickback they'll both be bad!!
Thanks, Ernie. Yes, the might both be bad, but not equally bad. It's kinda like this; it would hurt to get hit by a baseball that a middle school kid threw at you. It would hurt a lot more to get hit by a ball that major league pitcher threw at you. Between the much slower speed and the 50% less control surface, I bet it would be a lot less bad with a smaller blade. Do you have any experience with a small blade kickback? Obviously I'm just speculating about the effect of the control surface, but I don't know how it couldn't be a factor. The linear speed is factual, and significant
I learned this from a man named Bob Chase on TH-cam a couple years ago. A cabinet maker/craftsman. His channel is called The Master Woodworker. He’s doesn’t make many videos anymore unfortunately but He’s a great man, an old timer, that many people would appreciate to learn from. There are a few videos on his channel that explain specifically why he gave up the 10in blade 2-3 decades ago. I know that he didn’t invent the idea, but I believe it has mostly been his influence which has caught on to other youtubers over the years and I’ve seen others who now do the same... Although, he never used a riving knife, which is why I never felt totally comfortable adopting the change in my own shop. I prefer to use a riving knife so your video today has great value to me regarding the company who made your custom knife. I will be looking into whether they can make one for my saw, as I know I will enjoy using a smaller blade for a majority of my basic cuts. It makes sense in so many ways. Thanks!
Thanks for the feedback and for the tip on Bob Chase. I'll check out his channel. I've never seen a TH-camr do this before, but I learned about it from a guitar builder.
ToolMetrix That’s awesome to hear. A luthier would probably really benefit from thIs method... I think you’d like the gentleman a lot as he went on many trips over many years, traveling the world doing missionary work, building things for different communities in need. A craftsman from a generation which we don’t have many left from anymore... One of the videos is titled Taming the Tablesaw.
It’s great that he recorded some videos to pass along some of that knowledge. I’ll definitely check him out.
I’m thinking of getting a small sheet of 1/16” aluminum from HD. My Laguna Fusion F2 tablesaw has a standard riving knife and I added a thin kerf riving knife. They are the same shape, so I am going to trace one of them onto the aluminum sheet. Then I will use double sided tape to fix the sheet to a small piece of 3/4” Baltic birch. For my riving knife, I’ll use a piece of plywood that’s about 6“ x 7“. I plan to use a 1/4“ blade on my bandsaw and cut the aluminum/Baltic Birch sandwich to rough shape, staying just outside the layout line. Then I’ll take my laminate trimmer with a small trim bit to take the riving knife down to its final size. The trim bit should have no problem with the aluminum but since I have a bunch of bits, I’ll probably use an older one anyway. There’s a couple of holes and a couple of slots on my riving knife. I will use a combination of the drill press, bandsaw and possibly my jigsaw to finish these out. Finally, to smooth everything out, I will use a hand file followed up by my spindle sander. I hope to get this made quickly because like a couple of you all, I prefer to have a riving knife with every blade. Just in passing, I also use a Microjig Grr-ripper and love it. I think I was one of the first people in the country to buy the Grr-ripper way back when at a woodworking show. I hope to get this riving knife made soon and will report back here when done.
That sounds like a good approach! Let us know how it goes. A scroll saw would probably work as well.
Great video, I am wonder why not use the blade stiffiner with the smaller. It may reduce the cut depth even more but if that isnt a problem you could remove any wobble that may occur even with the smaller blade. Also perhaps overkill.
Hi Lincoln, Sure, that would work. Not a bad idea.
This is why they make most dado stack blades 8”. The kerf is much wider + a flat top grind, so the extra cutting force is very important!
Yep that’s a great point 👍
I used to frame houses and have maybe twenty 7 1/4" blades left from that. Any time I am breaking down salvage lumber or any lumber than might be dirty or have nails, I use one of those blades. If I hit something I can afford to throw the blade away. The same would apply to the blade you mention, at less than $15 ruining one would not be a disaster. Also, everything else you say is true. Running a good smaller blade is hardly a compromise.
Great feedback. Thanks for sharing, Barry. Cheers 🍻
@@ToolMetrix I failed to mention, if the 7 1/4" diameter is what bothers you, they make very similar 8" blades. I have not check the exact specs, but they are similar. Costs only 1" on cut depth.
Thanks Barry. I’ve seen those but haven’t tried them yet.
