Description
Route, clean, and prep cracks in concrete and asphalt for caulk or sealant with the OX Ultimate Crack Chaser. The V-shaped diamond segments widen and clean failed cracks in one pass so your repair material can bond properly — no more scraping, brushing, or chipping by hand. Runs on a standard 4.5-inch angle grinder with a 7/8″ (22 mm) or 5/8″ (15 mm) arbor.

Safety
Run only on equipment rated for 4.5″ blades. Match the blade’s arbor to your grinder before mounting. Wear ANSI-rated eye protection, hearing protection, and respiratory protection when cutting silica-bearing materials — concrete dust contains crystalline silica. Use HEPA-filtered dust extraction or wet methods where possible.
