Topic tags/keywords: question blade miter saw tip

I was wondering about tear outs on cuts. Right now I am using a 40 tooth blade on my Craftsman 12” compound miter saw. It is what was on the saw when I bought it. What do I need to look for in a blade to cause less tear out? More teeth, angle of teeth or something else?

Sorry – I didn’t see that this was a miter saw. I guess my head is thinking “Scroll saw!” ;)

Maybe make a zero clearance fence for your miter saw?

A blade with 60 or more teeth would be considered a crosscut….An alternate top bevel (ATB) and a negative hook angle are also considerations in a crosscut blade that help eliminate tear out

-- Measure "at least" twice and cut once

Tearout can be caused by blade runout and incorrectly set teeth on a blade. If your saw is set up properly and you have a good crosscut blade, tearout should be minimal ay best. There will always be variations in blade set and runout with consumer grade tools.

When I see excessive tearout on a miter saw cut I do some clean-up and re-tune the blade 90 degrees to the saw table (doesn’t seem to require much deviation to produce that “fuzz”).

Saw blade tips

It’s important to get good quality blades that have good steel, precision balance, good carbide, etc….once you clear that hurdle, more teeth typically means a cleaner cut if all else is equal, but there’s never a free lunch… it also means more resitance, more tendency to burn, slower cut, generally higher cost, etc. The cleanest cutting blades will have a high tooth count (typically 80-90T for a 10” or 12” blade) and a HI-ATB grind, which is the cleanest slicing grind available, but also has the shortest edge life….that combination should leave the least amount of tearout possible in a saw blade. If you keep it clean, it should still offer pretty good edge life for a hobbyist. You may also find a that a good ATB grind on a high precision blade with a high tooth count will also do very well, and should give a little longer edge life.

Thank you for all the input. I just came in from Lowe’s where a new Dewalt 96 tooth blade just happened jump in my cart.

Now to try it out.
