Tomahawk Concrete Crack Chasers make crack repair faster, easier, and less physically demanding. Instead of spending hours on your hands and knees with a handheld grinder, operators can comfortably stay on their feet while following cracks with precision and control. Designed to help contractors route cracks quickly and consistently, the walk-behind design reduces fatigue while improving productivity on large repair projects. The included 4.5 in. grinder comes ready to work right out of the box, making it easy to open, widen, and prepare cracks up to 3/4 in. deep for polyurea, epoxy, sealants, and other concrete repair materials. Connect a vacuum system to the integrated 2 in. dust port for cleaner jobsites, improved visibility, and reduced cleanup with OSHA compliance. Built with a heavy-duty steel frame for stability and durability, Tomahawk Crack Chasers are built tough with a 2-Year Warranty with nationwide parts and service helping you stay productive and on schedule.
