If your saw is more than 1.5hp get the Full Kerf. A Thin Kerf blade is great to have in the arsenal regardless for those times you want to save as much wood as possible. Also great for preserving exposed joinery and grain match when removing box lids. *Ripping Blade 24T* The best for rip cuts and terrible at crosscuts. My most used blades. *Crosscut Blade 60T/80T* Fantastic for crosscuts but terrible at rip cuts. Low or negative rake makes them great in the Miter Saw or for fine cuts in plywood. *General Purpose Blade 40T* Great all around blade for non repetitive cuts in wood UNDER 1.25”. Great for shop jigs and plywood. *Combination Blade 50T* Great all around blade for non repetitive cuts up to 2 and 1/8” inch thick. Not good for plywood though. *Dado Stack* Best for dados, grooves, rabbets, half laps, bridal joints, and hogging out material when you’re not cutting all the way through.

You mention less than and more than 1.5hp. However what if your table saw is *equal to* 1.5 hp (as mine is 😂). In my search on the web it seems to be up in the air and have even seen some rather large debates. What is your opinion?

[@fdort3971]

I'm still undecided on which to get...I can only afford one right now...sigh. @KatzMosesTools Tamar 3x3 customs speaks highly of you so you are part of my research. I see blades with slice or openings every so far along...it's my understanding it's to help cool the blade. If I have a blade with none...is it safe to make my own thin spaces or cut outs? If so is there a particular shape or size and how deep would I go? I inherited a bunch of blades from an uncle when he passed away.

[@biggorilla83]

I bought one of the cmt blades you recommended from the video back when you went to the blade sharpening place. I previously had a Freud cause I thought it was close enough to good. The difference in cut quality is more than night an day. I just can't even believe how much better of a blade it is. It feels like my saw gained an extra HP or something. The cuts feel less dangerous cause I'm not pushing the cut through, it's just gliding through instead. It is seriously a big deal everyone should invest in.

[@katzmosestools]

I wish I could pin this comment. It's the absolute truth! Thanks for sharing my friend! Side note: the brother who designed the Freud blades started the CMT line just 4 years ago. Since coming on board he's been awarded more than 10 patents for blade technology. He's done all the things Freud wouldn't let him do because they wanted to keep costs down.

[@archholder185]

Excellent presentation! Well presented, a few frames of slow motion conveys more information and knowledge than a half hour of verbal explanation. If other power tools presentations use this format and level of research into the subject at hand you may set a high bar for others to achieve and likely raise the level of an entire industry.

[@daveyJ213]

Jonathan, I'm glad you are back and healthy. Thank you for the great information; well done!

[@blaizewood1871]

THIS is a quality KZbinr!

[@AggieTreed]

Awesome video. One thing to add though, the difference in the plate thickness on the thin kerf VS thick kerf and how that can influence stability of the blade. Forrest, for instance, recommends to use a blade stiffener on the thin kerf because they can sometimes flutter due to that thinner plate.

[@katzmosestools]

In my personal experience a blade stiffener severely limits your cutting depth and doesn't have a noticeable effect in my opinion. I could certainly see a use for it in some harder woods but I used one for about a year because someone recommended it and then once I took it off I never went back.

[@AggieTreed]

@@katzmosestools I definitely agree with it limiting the depth of cut. I have one and never use it, but I also only use full kerf blades since I have the Industrial Sawstop. It'd be interesting to see if there are situations where you could cause the flutter and compare one with and one without the stiffener. Maybe it is just snake oil, idk

[@bulento9398]

[@dfrechettej3v]

Nice video. When I started with my JSS Pro (1.5HP) from SawStop, I purchased several quality thin kerf blades just to discover that they caused pinching between the riving knife and the fence, so I switched over full kerf blades (CMT Chrome & Amana Electro-Blu) and all my problems went away.

[@BrianThorstad]

Great video on multiple fronts. - lots of good info! - great slow mo, besides being cool, it really helps understanding what our blades are doing. I agree on the premium blade being a consideration. I have both a CMT crosscut (IIRC at your suggestion a while ago) and a Ridge Carbide rip blade. Love them.

I think this video is going to cost me a lot of money 🤫 I’ve understood different blade types before but never really respected it enough to ever using anything but a combination blade, except when I’m using thin veneer plywood. I’ve used TSP to clean my Blade before and it took off all the markings, so it probably would do the same for the slick coating as well. Thanks for this in-depth look at this, Jonathan.

[@ohasis8331]

That was an excellent video with a ton of information. It did seem too much too fast, probably due to editing and to cover the material.

[@mikewashere9660]

Glad to see you are doing well, been awhile, me too, changing gears at this point, come with age I suppose. I'll be checking out you shop, perhaps I could use a new blade or two for the table saw, the miter has gotten most of the new blades of late, but in changing gears, the table saw will need a new set, plus with be researching your collection of blafe and bit sharpening job shops! Safety first, last, and in between, provides for happy fabrications! PS. Well damn the bad luck, guess I have to make a 150 mile round trip you're sold out of the blades I like to use! ...maybe next time!

Happy you're carrying them and I can support you!

[@sgsax]

Great info as usual. I need to watch again and take notes. I've got an old (80's vintage) Craftsman 12" direct drive table saw and have always been torn about buying 10" blades for it, feeling like I'm cheating myself out of the extra radius. Thinking rationally about it, the only time it would make a noticable difference is if I'm trying to resaw or otherwise cut through extra thick materials, so I probably shouldn't feel bad about using the smaller blades. Do you have any thoughts about this? Is there anything else I might be missing out on by using blades smaller than the capacity of the same? Thanks for sharing!

I've been working with hardwood a lot more lately and this information makes a lot of sense now. Bought a big ass piece of purple heart, maple and cherry recently. Each 8-9' long, 3" thick, 8-10" wide. Do not recommend repetitive rip cuts on 2" purple heart using a delta 76-725 on a 15 amp circuit with an 80 tooth crosscut blade. Picked up a CMT 201.024.10 for this type of work and while I have not had a chance to use it due to being sick from the plague, I'm excited to see what it's all about. Hoping it speeds things up! 🙏

The manual says you should run that saw on a dedicated 20A circuit to put less stress on the motor. If you're cutting a lot of super hard wood like that, it's definitely worth upgrading the circuit to protect the saw.

Get a dedicated ripping blade. That's a super powerful saw and with the correct blade you shouldn't be getting burning

[@nwngunner]

also make sure your fence and blade along with miter slot are properly aligned.

[@csimet]

Great tutorial! Questions on the use of thin kerf blades... Do you find it a benefit to use (a) blade stabilizer(s) with them to reduce possible wobble? Are they worth the expense? Also... any benefit to placing a spacer/shim between the thin kerf blade and saw arbor, so that the blade to fence distance remains the same as that for a full kerf? I assume switching between thin and full causes the saw fence scale to be thrown off by the difference between the blades (meaning you may have to re-adjust the fence scale each time because the cut distance changes). Just looking for help before I investigate further. Tx!

[@katzmosestools]

I have never found a stabilizer to make a noticeable difference. It is way thicker that the 1/32 difference between a full and thin and cause you to lose a lot.of cutting capacity. You DON'T want to put it between the motor and the blade. The correct side is the nut side. Will cause all sorts of problems with the riving knife and the drive shaft.

[@csimet]

@@katzmosestools Appreciate the fast reply! Understood... on the stabilizer use. What about shimming the thin kerf blade to make the right side of the blade align with a full kerf (again, so the blade to fence cut distance does not change)? My old Craftsman does not have a riving knife and I use a MicroJig MJ Splitter (one setup for thin, one for full kerf). Tx again!

[@katzmosestools]

@@csimet it doesn't change to the left side of the blade but changes by 1/32 between the fence and the blade.

[@johnhendy1281]

Question... Doesn't the tip do all of the cutting? I was comparing the shot at 13:33 and the tips of both look to stick up about the same amount above the metal body. I'm imagining this is where the sharpening mostly occurs? Alternatively sharpening is grinding the face and the CMT looks thicker on that direction but not by a ton. Could you put this extra carbide in practical terms? Like n sharpenings at $x vs buying a new blade? I've never had a blade sharpened so I don't know. On one hand, seems like more carbide is better... On the other I thought "huh, adding more carbide that doesn't actually do any cutting just to say there's more carbide would be a slick marketing technique."

Quick question for you since I can’t seem to find it anywhere else… how do you cut a Dado in 12mm BB? The CMT precision set will dial it down to 1/32nds, but 12mm is ~15.16/32nds, leaving 15/32 too tight and 16/32 too sloppy loose

[@katzmosestools]

Good question, there's 6 or so shims that come with it to really dial it in. You put them between the chippers.

[@ender1553]

@@katzmosestools Thanks! I was hoping there might have been some metric shims to make it easier to dial it in, ie, set it up for 15/32, and then just add in the shim for the .16 difference which is about .0037", and if you wanted 8mm, use the 5/16, then add a .00246" shim for the difference. I've only personally worked w/ imperial, but was looking to start doing some drawer boxes and nice cabinet work and BB was metric.
