I thought I would share some photos of my Black Diamond Drill Bit Grinder that I bought a while back. Model 1B. It was made in the 1940’s according to the guy at the Black Diamond web site. It was kind of dirty so I did some cleanup. I have read where some people feel the Black Diamond is the “Cadillac” of drill bit sharpeners.
This drill bit sharpener uses a single collet for each size drill bit from #70 to an 11/32”.
First the drill bit is inserted into the collet holder. At that time the depth and angle can be set by inserting the collet holder into the drill bit “locator” on top of the machine and tightening the bit in the collet. There is a different locator for different groups of bits from smallest to largest.
