I recently started using a 1/2" diameter spiral bit to do some template routing. I am wondering if these spendy bits can be sharpened, either professionally or by myself?
That's an interesting one. I didn't know Bosch did solid carbide. They are certainly cheap.Here's another source for spiral bits. I haven't found any cheaper than this place.
