A unique long wearing one-piece casting won't wear out with extended use in concrete like steel tools. The blade is belt polished for cutting clean, smooth edges every time. This chamfer tool is designed for creating professional chamfered edges on round support piers. The 1/2 In. radius edge extends down 1 In. for proper coverage on the top of the cylinder. Curved sides create easy movements in a round fashion. The chamfer tools fits around 36 In. diameter support columns. This durable tool has turned up edges to move through the cement without fear of gouging. The slope created on the edge can be varied depending on the wetness of the concrete and the angle and pressure of the Edger. The smooth wood handle is secured to the casting. Kraft Tool Co.® has been an American manufacturer of quality hand tools for the concrete, masonry, asphalt, plaster, drywall, tile, floor covering, and leveling trades since 1981.
