A popular choice for commercial and government jobs. The 8 in long heavy duty stainless steel blade moves smoothly through concrete driveway and sidewalks. This groover creates five 1/4 in D, 1/4 in W grooves 2-1/4 in apart on center. These parallel lines provide a safety tread effect on high traffic areas such as driveways, sidewalks and stairs. The 8 in tool provides thorough coverage on sidewalks, driveways and slabs. A full top plate provides additional strength to move through the cement with ease. A steel mounting welded to the top plate attaches the smooth wood handle. Proudly made in the USA. 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 for over 35 years.
