New-Style Drill Bit Sharpener FARM SHOP Miscellaneous 24-6-30 "I am a metal worker by trade so I always need sharp drill bits. But I've never been able to find an inexpensive bit sharpener that really worked," says Stan McDonald, Foxboro, Ont., who finally decided to see if he could design his own sharpener.
The result is an attachment for benchtop grinders that he says does a near-perfect job. "It compares favorably with sharpeners that cost thousands of dollars. It's easy to use and built to last. Features all-metal construction - no plastic," says McDonald.
"When I set out to design it, I started thinking that the textbook method for sharpening bits does work, it's just difficult to maintain a good pitch to the cutting edge. I decided to make a device that would make it easy to sharpen bits on a conventional grinding wheel.
It's designed to attach to Delta 6-in. bench grinders but can be adapted to others by drilling a couple holes. Sharpens any bit up to 1-in. dia., regardless of length.
Sells for $185 U.S. attached to a Delta grinder, or $124 by itself.
