80 vs 90 tooth blade on miter saw?

[marlinspike]

Given my experience with them on the table saw, I am a big believer in Forrest blades. I am buying a miter saw, and want to put a Chopmaster blade on it. Am I really going to notice a downside to the 90 teeth of the Signature line to the 80 teeth of the standard? I feel like once you're that high in tooth count a few fewer can't hurt anything, but never having used one maybe I'm wrong.

I can't imagine your life changing over this..

The higher tooth count will usually yield a cleaner cut. Slower and harder though.

You don't know just how little I have then. This could make or break me. It's all I have left. I got nowhere else to go. I got nowhere else...I got nothing else.

what species of woods? whats the typical size of cuts? what saw?

I have a Dewalt 80T and a CMT 96T and I bet even I couldn't tell the difference in the cut between the two in anything I've done.

The 80 is ATBR 4+1, while the 90 is ATBR 2+1.

What that means is the 80 will have 4 angled teeth, then one raker, while the 90 will have 2 angled teeth followed by one raker.

For strictly cross cutting (90 degrees), I'd expect a cleaner cut with the 80. For miter cuts, the 90 might be a LITTLE better.

Definitely SLOWER. The more teeth, the less gullet space to haul away the waste. The thicker the stock, the less teeth you need. Ideally you have at least 2 teeth in contact with the cutting line at all times.

Whoops, I hadn't noticed that.

It's like the difference between typical 50 and 60 tooth blades on a tablesaw, where I prefer the 50.

Ive only found big issues in high tooth count blades when cutting thick + hard materials like Oak. More teeth created to much friction and caused burning.

With a quality blade like a Forrest I bet you could easily get away with 80 and never notice a difference in really fine cuts.

Cheaper to sharpen, too.
