The MILWAUKEE DIAMOND MAX Turbo General Purpose Diamond Blades deliver the power to cut through hard aggregate. Designed with a unique diamond formula, these blades deliver up to 5x longer life in concrete. The serrated turbo rim is engineered to maintain speed and power in hard aggregate and other materials like concrete, brick, block, paver, and roof tile, while the notched turbo edge provides cleaner finishes. The vented steel core keeps the blade cool and ensures consistent cuts throughout the life of the blade. For use wet and dry.
