The Milwaukee SDS-PLUS 4-Cutter MX4 5-Piece Drill Bit Kit features solid carbide heads that deliver up to 5x longer life in concrete with rebar. Engineered with rebar guards to provide maximum durability in hard aggregate and rebar. MX4 4-Cutter bits are designed with sharp centering tips for exact spot drilling in concrete and metal decking. The 4-cutter design prevents lock-up in rebar， reducing downtime. Variable flutes remove dust faster， reducing heat and delivering up to 20% more holes per battery charge. Wear mark indicator shows users the end of life when the bits no longer meet the ANSI requirement. The Milwaukee MX4 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications. The Milwaukee 7-Piece SHOCKWAVE Carbide Hammer Drill Bit Kit uses sharpened carbide to deliver up to 5x longer life in concrete and up to 2x faster drilling into masonry materials. 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/drivers.
