In four years of having it, i just triggered my saw stop brake for the first time – fortunately not on my hand.

When I switched from a regular blade to a dado stack, I neglected to adjust the brake level down to accommodate the dado brake I had just installed. The brake engaged immediately when I turned on the saw.

I already ordered a new brake, but I read I’m supposed to replace the blade as well. I’d rather be safe than cheap, but I can’t see any damage to the dado blades (was only using the outside cutters – no chippers) – they weren’t going full speed when they hit the break since it was pretty immediate, but they were jammed into the soft aluminum on the brake pretty good.

Can I keep using the dado?

Secondly, if the answer is no, does anybody know if I can purchase replacement cutters rather than buy a whole new set (it is a Freud 8” set).

Thanks!

Try here for new cutters. Not sure if it’ll be cheaper.

At least you know it works. I’d say that if the blade looks fine and cuts well, keep using it.

I have reused several regular blades with no problems, and I think yours will be alright also. Just inspect carefully for missing carbide tips or bent teeth. I expect the instruction to replace the blade is just a liability precaution by Sawstop.

Reading this post raised another question in my mind. A good friend of mine recently mangled his thumb in his table saw because he got careless after he turned the saw off, but the blade was still spinning. Does the Sawstop brake work if the saw has been turned off?

The safety system is still active after power is shut off until the blade is fully stopped.

I would take the blade to a reputable sharpener. They will typically give the blade a good inspection for cracked or chipped teeth. Notify them of the brake incident. They should be able to inspect it more closely for any damage.

I think that’s good advice. I worried as I posted my reply that a loose tooth could cause problems.
