An electrode sharpener has a main body that is threaded directly onto a rotary tool. The body includes a base and a housing connected to the base. The base has a threaded bore and a smaller passage centrally located above the bore through which a wheel mandrel protrudes. A shoulder is machined out of the upper end of the base. The housing, which is preferably made from round stock, is bored out such that it slips over the upper end of the base, with lower ends of the housing abutting the shoulder of the base. Fasteners are included to affix the base to the housing. An abrasive grinding wheel is mounted for rotation on the wheel mandrel and is located within the housing. An adjustment grip with knurled edges is adjustably connected to the outer surface of the housing.
