Milwaukee 48-20-9016 Drill Bit, 5/16 in Dia, 6 in OAL, Wide Flute, 1/4 in Dia Shank, 3-Flat Shank

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. The extended life of the MILWAUKEE® carbide hammer drill bits provides the ideal solution in concrete, brick and block.
