1/4" Shank Tungsten Carbide Rotary Burr Bit, Double Cut Carbide Burr Die Grinder Cutting Burrs Bit for Metal Working

Very happy with it

cuts really smooth in my die grinder, no chatter at all really. I havent used it a ton so I dont know how long itll last yet.

The die grinder bit is amazing. That was money well spent. Perfect for putting the finishing touch on torch cut holes.
