Sharpener Works On Big Drill Bits
A couple years ago FARM SHOW reported on an inexpensive new drill bit sharpener invented by Stan McDonald, Foxboro, Ontario (Vol. 24, No. 6). It was an attachment for benchtop grinders that sharpened any bit up to 1-in. dia., regardless of length.
  After the story was published, McDonald had a lot of requests for a larger bit sharpener. It prompted him to came up with a new model that will sharpen any bit up to 3 in. in diameter. It'll handle tapered or straight shank bits with two, three, or four flutes.
  McDonald says bits sharpened by his sharpener often work better job than new drill bits because you can improve them with his "four facet" sharpening method (see photos at right). "The result is a high-performance bit that will last longer and cut faster," he says.
  The sharpener weighs 75 lbs. and is designed to attach to a bench grinder. "It compares favorably with sharpeners that cost thousands of dollars. It's easy to use and built to last," says McDonald.
  The sharpener sells for $550 (U.S.) plus S&H.
