The bit cuts well. A groove had to be fitted to 22 kitchen doors. Had 8 and the white plastic was coming off the bearing. Also pay attention to the plastic on the edge of the bit. After it has come loose, the bearing must be replaced. I have to redo the door where it came off. A sheet of 3/4 birch costs $55 just to replace a door.
