I have had two brake activations in as many weeks, one on a dado stack (don’t ask). Neither destroyed the blade. Both blades will be back in service within a week.
Just putting out there: the popular idea that blades are always trash after an activation is not true.
That said, cheap big box store blades without carbide teeth will die a horrible death.
Carbide teeth are actually the part that gets destroyed on SawStop activations. Carbide is very brittle, so the sudden stop fractures it.
Yes, and they are consumable and replaceable by design, which goes to my point: the blade is not irreparably destroyed by the activation.
The missing teeth need to be replaced and the plate needs to be re-checked for runout, but most carbide-toothed blades are repairable.
How much does it cost to repair a carbide toothed blade, and how accessible are shops that can perform those repairs? Is it realistic that most consumers would be able to get a blade repaired rather than just running to the hardware store and getting a new one? Not being snarky; I've just never been under the impression that repairs could really be done for less than the value of a new blade.
