The MILWAUKEE® 5/8″ x 16″ x 18″ Carbide Hammer Drill Bit uses sharpened carbide to deliver up to 5x longer life in concrete and up to 2x faster drilling into masonry material. Engineered with a precision ground tip, these Milwaukee drill bits deliver faster starts and less walking in concrete, brick, and block. The wide flute design removes dust faster, reducing heat and delivering more holes per charge. These bits feature a 3-flat shank for better grip and control. The extended life of the Milwaukee Carbide Hammer Drill Bits provides the ideal solution for drilling in masonry materials with cordless and corded hammer drill/drivers.
