Hey guys, we're in the market for a new drill sharpener for our shop and haven't seen much of a choice besides the Oliver sharpeners. Needing one that will sharpen up to 3" at least. Was wondering what sharpeners you all use at your shops or have any others that are good brands. Or if anyone knows where you can get parts and grinding wheels for a Mohawk model 100 sharpener. Thanks in advanced!
