Drill bit sharpener - video

[Frank S]

anyone caught grinding on the side of any of my bench grinders gets to buy me a new rock even if they don't grind long enough to do any damage unless it is a cupped grinding rock made for axial grinding. I was privileged to buy 3" by 18" rock when I first started out before I was even a teenager. I was grinding on the side of the rock when the plow shear caught and wedged 10 HP arbor grinders get ugly real fast. nothing against those who do it is just my policy. I also grind using the full face to the rock because I like even wear, groves worn in the rocks
