摘要： A precision drill sharpener and grinding wheel assembly is provided, as is a corresponding drill chuck for use with the drill sharpener, in which the drill sharpener includes a lever and spring clip alignment subassembly for properly positioning a drill in the drill chuck, and sharpening ports for sharpening the drill and splitting the drill tip, the sharpening ports being positioned such that a single grinding wheel assembly is used to both sharpen the drill and split the tip. The drill sharpener uses a small diameter grinding wheel operated at high speed to provide cutting rates comparable to large industrial sharpeners. The drill chuck is of short length, relative to most of the drills to be sharpened, and is open at a back end, enabling the manipulation of the drill by its shank relative to the drill chuck when disposed in the alignment subassembly.
