Our Carbide Hammer Drill Bits use sharpened carbide to deliver up to 5x life in concrete and up to 2x faster drilling into masonry material. Engineered with a precision ground tip, these bits deliver faster starts and less walking when drilling into concrete, brick, and block. The carbide-tipped masonry drill bits' wide flute design removes dust faster, reducing heat and delivering more holes per charge. Each bit is equipped with a 3-flat shank, providing you with better grip and control. The extended life of the MILWAUKEE® Carbide Hammer Drill Bits provides the ideal solution in concrete, brick, and block for cordless and corded hammer drills/drivers.
