Topic tags/keywords: question

Hey everyone. I’m a long time listener, first time caller! I’ve been watching the forums for a long time, but finally created an account. I’ve been doing searching, but don’t seem to be able to find anything about my question… If I missed it I apologize in advance.

I recently bought a new Diablo blade for my 12” Dewalt 715 mitre saw. I don’t remember if the blade was centered before I removed the old one honestly, but when I look at the new one it doesn’t seem to be centered. Here’s an image that hopefully shows what I’m talking about:

I’ve been trying to figure out how to center it back up in that slot, but I can’t find anything helpful (too far to the right). I know how to align it technically, but just not actually centering the blade. It’s using the same screw and 5/8 arbor that I removed from the old blade and the new blade is the same thickness as the old (It’s the Diablo 12” 80-tooth blade – I love diablo blades…).

Any help would be great! If I didn’t explain it well enough please let me know.

edit: No idea why the photo is sideways…it’s normal when I view it outside the post.

Does it cut square? It looks like it’s off a little, it could just be the picture though. If it cuts square I wouldn’t worry about it. If it isn’t square, adjust it ‘till it is. There should be instructions in the owners manual or online.

I’ve seen saws that the washer on the side of the motor has 2 flats in the hole to keep it from spinning on the shaft. If these flats aren’t lined up with the flats on the shaft it will not seat and the blade will not center.

Hope this helps.

The distance it is off looks suspiciously like a backer washer some saws have. My old Delta miter saw had one. Besides the nut and outside washer it also had one behind the blade. If it had one maybe you dropped it without knowing. If the blade is square and doesn’t wobble it’s fine. If you want it centered add an inside fender washer.

Thanks for the replies!

Thetinman – that’s what I was thinking, but I looked around to make sure I didn’t miss anything. There was just the single 5/8” arbor that I took off originally, and the blade lock and screw. That was it…

Tenfingers58 – You both had the same thought I did. I thought it was just missing a washer on the opposite side, but I don’t see one. I can look on Dewalt’s site and see if there is one available to move it over.

It doesn’t seem to affect the spinning and a quick look with a speed square shows that it is squared up. I haven’t actually tried to cut anything yet. After I make sure it’s aligned then I’ll check to make sure. I just wanted to make sure it was okay to use like that.

Thanks for the help!
