Concrete Joint Cutter - Ninja Joint Cleaning Blades

Designed for maintenance crews removing old joint sealant from highways and warehouse floors, these Ninja Joint Cleaning Blades from Diamond Products handle the demanding work of preparing control joints for fresh sealant application. The specialized blade design cuts through hardened sealant, debris, and deteriorated filler material without damaging the joint walls. These blades mount to standard joint cutting equipment and provide consistent depth control during cleanup operations. The cutting geometry removes material efficiently while maintaining straight vertical cuts along the joint edges. Each blade delivers extended service life in abrasive concrete applications where standard tooling wears out quickly. Built for highway contractors, facility maintenance teams, and concrete restoration specialists who need reliable joint preparation equipment.
