This SDS Max Tunnel Bit is engineered for the high-torque demands of heavy civil applications, eliminating the need for core-clearing by utilizing a one-piece design with high-volume sloped flutes. The 22-inch reach allows for continuous deep-hole drilling through brick, block, and reinforced concrete without losing momentum. Built to withstand the violent impacts of large-scale rotary hammers, the 3-cutter carbide head features specialized rebar chamfers that shear through embedded steel rather than binding, ensuring your crew stays productive on the most demanding deck or infrastructure pours.\u003c\/p\u003e\u003cul style=\"list-style: none;
