I have an old Freud 60 tooth LU82M Crosscut/Rip Blade with Triple grind teeth, I use to have it on my miter saw but I took it because it was boging my miter saw down, I am wondering is a good blade for plywood? I think it needs a sharpening.

Maybe a good cleaning and sharpening might just bring it back to life. A miter saw doesn’t have the power of a table saw and a dull blade can really affect the operation.

Perfect blade for plywood and melamine.

Not the right blade for a miter saw. You need a negative angle tooth for miter saws. They are also recomended for radial arm saws.

The LU82 is a full kerf multipurpose blade with triple chip grind (TCG) and a fairly steep hook. The TCG is know to be the a very durable grind, but not necessarily the cleanest cutting….a great choice for MDF, teak, high volumes in ply and other materials known to be tough on blades, but it won’t offer an exceptional cut as a plywood blade.

Which 80T TK crosscut blade did you get? Something with a Hi-ATB grind like the Freud LU80 (LU70 is the TK version), Forrest Duraline, Infinity 010-060, Infinity Ultrasmooth 010-080, CMT 210.080.10, or Amana MB10-800 offer the best cut in plywood, but there are lots of good ATB blades that’ll do a good job too.

A blade with a low to negative hook is suggested for a RAS and a “sliding” miter saw, but a straight compound miter or chop saw is fine with upwards of + 10° hook or so, but I wouldn’t use a steep 15°-20° hook on a CMS.

The TK806 should do well.

Correction to my info above..the TK version of the LU80 is the LU79….

It is a good blade for crosscutting.

Have your say...
