Do you like them thick or thin? I’m talking about table saw kerfs. My question is why would you want a thicker blade? I have a 3 hp saw. I am sure it would take all I give it; it takes the dado blades. What are your guys opinions on table saw blades?

Standard width blades flutter less than thin kerf blades, which sacrifice
stability for more cutting power in 110 volt saws.

I prefer a thin kerf blade and that is what is usually in my table saw.I do own thicker kerf cross cut blades but anymore leave them in their packaging.I leave the thin kerf in because I find it more of a jack of trades blade.

because they flutter less, and do not distort as easily, I lik standard thickness blades for most cuts, I really only use a thin kerf for veneer cutting, and small, delicate work. removing the extra wood does take more power, but it only slows your cut a tiny bit, and gives a cleaner cut.

thicker for me
stiffer cut
and i can move the fence
and keep better score
of 1/8” increments
than those .oblah numbers

I have never used a thin kerf blade. I never wanted the extra math when figuring waste. Also like David, it’s easier to move my fence to eighth inch increments.

Both. Which width to choose depends a lot of your saw and the material being cut. I’ve used both and had excellent results from both, but I gravitate toward high quality blades. I wouldn’t expect much from a mediocre quality full kerf blade, and even less from a TK. Now that I have a 3hp saw, there’s less incentive to use thin kerf, but when I had smaller saws, a good TK is a real blessing when hogging thru thick wood, and spares strain on the motor.

Even though the width differences appear very small, a full kerf blade is typically 33% thicker than it’s TK counterpart, and requires more power to spin. Full kerf blades tend to be more stable than TK blades, but that doesn’t mean TK blades are unstable…they’re not…high quality TK’s tend to be very stable. I’ve never had issue with a TK fluttering with or without a stabilizer, but a lot depends on the saw. A saw with runout issues using a cheap TK is very likely to have some flutter issues. A high quality thin kerf blade with proper tensioning of the body during manufacturing will rival the cut quality and performance of a high quality full kerf blade, and can be a very suitable choice for a home shop, smaller saws, and even in many commercial settings where wood consumption is a concern. The heavier mass of a full kerf plate will handle the stresses of heat better than a TK blade, so is often a more suitable choice for high volume applications.

There are legitimate arguments for both kerf widths, and the choice will come down to your personal preference and circumstances.

Thin is great for ripping. Thick is great for finish cuts. A good full kerf flat grind is also essential for specialty cuts that don’t go all the way through but don’t require a dado set.

When it comes to saw blades, get the best you can afford and read up on the different types. It’ll make a world of difference in your work!

I like thin, but don’t use them. Why you ask?
I have a Rigid 3650. With a thin kerf blade, the wood hangs up on the splitter. I’ve read articles on sanding the splitter down to allow for thin kerf blades, but as long as the saw is handling the standard blades fine, I think I’ll keep doing what I’m doing.

I prefer thin with a stabilizer. The stabilizer keeps the flutter down, but limits how deep you can cut. 99.9% of the time that is not a problem. If it is a problem, I can remove it for the cut.

I’m in the market for a regular kerf blade (or two) now. It will make measurements on the outside of the blade much easier knowing the blade is exactly 1/8”.

I can probably live without the flutter with a thin-kerf blade, but then again, it’s been so long since I’ve actually used a regular kerf blade on the table saw that I’m sure I don’t even see it as a negative right now. I’m sure I’ll notice the difference once I pop for the regular kerf blade.

Oh, BTW, I showed my wife the title of this thread…she said, “Oh honey, it’s not the size that matters, it’s the way that you use it.”

Didn’t know she understood that much about my hobby. :)

Well someone has to say this:

MY THICK-KERF BLADES MATCH MY RIVING KNIFE.

For me it started out as a safety issue with my G0690 where the manual clearly states such. Now, the other comments above about increased stability and easier math are just added benefits.
