Model Champ-3 will sharpen drills up to 3″… This was part of a package of machines we purchased from a drill & end mill manufacture. It appears to be new, but it’s missing the bed and Drill Indexing Gauge (see pictures). Make sure you look at the pictures, it shows what’s missing. It has a Dayton Industrial 1 phase 115/230v motor. JTS Machinery wants $2,526 for this grinder and MSC wants $4,170 for it. This is a real bargain for what the manufacture claims is the; Worlds fastest large bit sharpener. We can send you the link for the manual if you want.
