I assure you any 80 tpi blade will do fine. They discourage use of course blades because teeth are set wide and can snag on saw table. To get better precisoin use thin blades AND stabilizer discs. Stabilizer disc is simply larger washers designed to fit on either side of blade.

It shouldn't be hard at all. There are dozens of blades available that will work. Just look on Amazon for a selection. Anything advertised as a miter saw blade should meet the negative hook requirement. As far as number of teeth, 60 should be plenty for a smooth cut on trim/molding, and will be a better general purpose blade. And most of the blades listed should provide the RPM, either in the specs or on the photo of the face of the blade.

Thank you! I’ve researched endlessly and can’t find 10”, 80t, -5 angle, 6500+ rpm. All are max 6000 rpm or have a positive angle. Maybe I’ll have more luck with 60t

A quick google search for negative hook saw blade will find plenty of info.

They are typically used on sliding miter saws, not a saw like you have.

A 60T blade is plenty for your use.

I read that you can’t use sliding compound miter saw blades in regular compound miter saws. Is this not accurate?

As far as the RPM, I've rarely seen miter saw blades rated over 6000 RPM. I looked at the manual for your saw and the one I found says 6000 RPM, not 6500 RPM. If you're nervous you could always call their customer service folks to ask about this difference:

Here's a link to the whole manual: Delta miter saw manual

Strange, my physical copy says 6500+. Good idea, I’ll give them a call. Thanks!

7000 RPM blades are readily available.

(My bolding) Knowing these older delta saws, I would believe this 5200 RPM.

MOTOR SPECIFICATIONS

Your miter saw is wired for 110-120 volt, 60 HZ alternating current. Before connecting the miter saw to the power

source, make sure the switch is in the “OFF” position. The motor provides a no-load speed of 5200 RPM.

The speed should also be on the motor.

Thank you so much! The motor indeed says “use only 10 inch saw blade recommended for 5000 RPM a bigger”. How confusing that my manual says otherwise.

Call the folks atForrest and do whatever they say please.

Michelle-

The 6500 RPM could have been a typo, or a spec influenced by an over-zealous liability lawyer at Delta. In any case, I'm glad you've got some solutions now.
