So I got a great deal from a local building supply company in my area and now I’m looking to see what the best blade I should get for my use. It will be used for cross cutting hardwoods and plywood as expected in my shop. It will see little if any construction work unless I finish off some of the basement but no plans there.

I plan to build a miter saw station to assist in long board support and storage. From classes I’ve taken at a local woodworking store I noticed they use a Freud Diablo LU91M012 72 tooth thin kerf blade. I know they make 80 and 96 tooth blades as well but wonder what the best guide is in deciding on the best blade to get. I know the number of teeth makes a big difference but there has to be more to it than that. Suggestions on the topic or best places to find sound advice?

I have the same blade on my 12” slider and it works beautifully. Whichever blade you decide to purchase, having the -5 degree hook will increase the safety factor when using the saw a bit and, I think, makes for smoother operation.

I had one of those saws new and the supplied blade was pretty good as I recall. But Freud makes better blades in most cases than DeWalt does.

When I think crosscut, I think 80 tooth for 10” blades and 96 for 12”. I have an 80 tooth on my 10” Makita and it cuts well. I doubt if a few less teeth would make a huge difference though.

Have a diablo 80t fine finish on mine and it melts away wood.

Thanks for the replies. You hate to buy blades that only do a barely decent job. Of course using the saw properly makes a big difference. I’ve seen people speed through the cut and pull through it rather than push. I’ve seen where people will score their cut first with a very light pass and then cut especially on plywood.

So it looks like a good choice for this saw. It would mostly be used on hardwoods but will it cut plywood with little tearout? I see they also make a cabinetmakers blade with 72 teeth with a going price of about $110. Ant thoughts experience with this blade?

Thanks for that indeed. Well written and clear. I should have read this before methinks. I’ve saved this both in Favorites as well as locally on my hard drive as a pdf for off-line reading.

Thanks Again,
