Milwaukee® SDS-Max Tunnel Bits are ideal for drilling deep, large holes in brick, block, and concrete with SDS-Max rotary hammers. The fluted head design and 22" long shaft allows for continuous deep hole drilling without the need to clear out a core. To deliver increased durability in concrete with rebar, a large 3-Cutter tip avoids lock up in rebar. Aggressive carbide cutting edges shear through the rebar inside of concrete.
