Masonry Drill Bit 1-1/4 in x 18 in x 23 in SDS-Max

Milwaukee® SDS-Max 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, leading to up to 15% more holes per battery charge. Wide flute entries allow for 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 drilling holes for anchor applications and include a wear mark indicator signifying the bit is no longer ANSI compliant.
