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 it impacts hard aggregate and rebar, providing increased durability. The 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 provides accurate spot drilling. All SDS-Max drill bits are ANSI compliant for anchor hole drilling and include a wear mark indicator that signals the bit no longer meets ANSI requirements.
