Concrete Joint Cutter - Ninja Joint Cleaning Blades

Designed for professionals who need to clean out concrete joints before sealing operations, these Ninja Joint Cleaning Blades from Diamond Products handle both new construction and repair work. The blade system removes debris, old sealant, and loose material from control joints and expansion joints to ensure proper adhesion of new sealant materials. These blades work in standard joint cutting equipment and deliver consistent depth control across extended runs. The cutting design minimizes dust while maintaining clean vertical walls in the joint channel. Suitable for commercial flatwork, warehouse floors, and parking structures where joint maintenance is critical to long-term slab performance. Built for concrete contractors and facility maintenance teams who maintain large-scale concrete installations.
