Milwaukee SDS-Max 4-cutter rotary hammer bits feature a four-cutting-edge carbide head designed to drill faster, straighter, more precise holes in tough concrete and masonry, including material with rebar. The extra cutting edges power through hard aggregate and reinforcement that can slow or deflect a standard bit, so you stay on target in demanding conditions.
Great Lakes Power Tools carries Milwaukee SDS-Max 4-cutter bits in a range of larger diameters and lengths, ideal for heavy concrete drilling and rebar-reinforced work. Whatever the hole, there's a 4-cutter SDS-Max bit here to match your hammer and application.
