Manufactured in Chicago by the Duro Metal Products Company during the early to mid twentieth century, this tool was a staple of professional service stations and backyard mechanic garages alike. Used to lap and grind engine valves into their seats for a tight seal, its internal gearing converts a continuous hand-crank motion into a reciprocating back-and-forth rotation. This heavy-duty tool is perfect for display on a workshop shelf, addition to an antique tool collection, or as a rugged decorative accent for an industrial or automotive themed space.
