Well yesterday I started wood burning again - and not the type that's a hobby/art. The kind where my red oak gets burned by my TS blade and there is a new mandle (man candle) smell that fills the workshop.

I was using an Avanti 60T ATB blade. How long should a blade like this last? I think I've used it for less than 10 hours.

I'm considering getting an 'Industrial' blade. The the Freud LU line. How long does a blade like this last in comparison to the Avanti line?

Thanks a lot!

Depends on what it's been used on, and how it's been cleaned. A dirty blade will dull quicker than a clean one, and the carbide may just be dirty, not dull at all... Try cleaning your blade and test...

I have a stock Skil blade in my circular saw that is at least 10 years old and still cuts like new. But I clean my bits and blades...

What kind of cutting are you doing with that 60T. I would be using a 48T for ripping and rough out work, switch to the 60 for finer detail stuff. Would seam to me if you start chunking a lot of wood through a blade faster than it can cut your going to get burning. Not saying that's what your doing, just a thought.


I have a Delta (leitz)48T blade I have used all season, it was until my bro ran a nail through it that is was time to take it in for sharpening. I also have a 60T Delta (leitz) blade and it gets used very little and seams to need sharpening soon, wander if it has something to do with the tooth count.

That would be my first suggestion too. 10 hours is nothing that should wear the carbide. This may be a dumb thought, but is your fence square (were you ripping with the fence on ?) If something is not lined up it will burn. A dull blade usually just cuts slow, not burn so much I don't think.

Yeah, I uh, kind of learned that one the hard way... I guess screwing up projects is a good way to learn to take care of tools better...

It should last a lot longer than 10 hours. It's worth repeating....clean the blade and see what you've got. How long a blade lasts depends on how it's used (and maintained).

The Freud Avanti, Diablo, and Industrial lines are made in the same plant from the same materials. The carbide is smaller on the Avanti and Diablo lines, and there are some minor design differences, but a comparable "LU" series blade isn't likely to stay sharp any longer under the same conditions. It will withstand more resharpenings though. The Industrial line offers both full and thin kerf blades and has a much wider selection than the Avanti and Diablo lines.

After cleaning the blade I would definitely check the trueness of my rip fence. If the fence is not absolutely parallel to the blade you will being trying to push the wood through kind of sideways That will definitely cause burning. I would agree with Nate, too. 60 teeth is a little fine for ripping.

As for your original question, as to how long a blade will last: About one nail.

60 tooth no good for ripping
Second check the blade for SQUARENESS to table top
Check fence for parallel to blade.
If just ripping then a 24 tooth rip blade is the way to go.
60 is too fine for anything but crosscutting.
As far as how long? Good blade set right saw blade should last several years depending on how much heavy usage and the woods cut. Oak is easy cutting, Cherry,Maple,hickory etc r way tuffer

60T is pushing the envelope a bit, but it really depends on the thickness of the material, blade height, etc. Freud suggests no more than 3 to 5 teeth in the workpiece for ripping, which is doable for a 60T if the material isn't too thick. The TK/Avanti has a fairly steep positive hook angle, and if sharp, will easily rip up to 1" and possibly more. A 24T will have an easier time but is marginally acceptable for glue ready edges, depending on the blade and the stock. I tend to turn to a 24T for 2" and up, but it depends on a lot of things.

The first thing a saw sharpening shop will do is clean the blade to see what the condition is. I oil my blades after I clean them, this works for me.

Lots of good advice here but more information about the application(s) would be helpful. The Avanti and Industrial blades have the same carbide, however, the Industrial have thicker tips for more sharpenings.

Charles,

Thanks for making that clear. I was thinking the same thing, that industrial just meant thicker carbide....

How long should a TS blade last? Abe Lincoln was once asked how long a man's leg should be.... His reply? "Long enough to reach from his hip to his foot...."
