Our SHOCKWAVE carbide hammer drill bits use 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 bits deliver faster starts and less walking in concrete, brick and block. Wide flute design removes dust faster, reducing heat and delivering more holes per charge. Equipped with a 1/4 in hex shank, MILWAUKEE SHOCKWAVE carbide hammer drill bits are the ideal solution for drilling in masonry materials with both impacts and hammer drills/drivers.
