Masonry Drill Bit 1/2 in x 15-1/2 in x 21 in SDS-Max

Milwaukee® SDS-Max drill bits deliver faster drilling speeds, increased life, and greater cordless efficiency. The breaker point pulverizes material, resulting in 20% faster drilling speeds. Rebar guards protect the bit when hitting hard aggregate and rebar, extending life. Variable flutes remove dust from the hole more efficiently, resulting in up to 15% more holes per battery charge. Wide flute entrances enable faster drilling speeds, while reinforced flutes prevent bit breakage, increasing durability in tough concrete applications. The centering tip allows for precise spot drilling. All SDS-Max bits are ANSI compliant for anchor hole drilling and include a wear mark indicator that signals the bit is no longer compliant with the ANSI specification.
