More Information


SDS-Max carbide bits feature the SDS-Max drive system for fast bit changes and efficient power transfer from the hammer to the bit. Breaker points pulverize the material leading to up to 20% faster drilling speeds. Rear guards protect the bit when hitting hard aggregate and rebar leading to longer life. Variable flutes remove the dust out of the hole more efficiently. Wide flute entrances lead to faster drilling speeds, while reinforced flutes prevent bit breakage, rendering increased durability in tough concrete applications. The centering tip allows for exact spot drilling. All SDS-Max drill bits meet the ANSI specification for drilling holes for anchor applications and include wear mark indicator when signifying when the bit no longer meets the ANSI spec. Use only in SDS-Max drive hammers.
