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. The wide flutes allow for fast dust removal. 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 or drivers.
