This 1-3\/4\" x 22\" SDS Max Tunnel Bit is engineered for the high-torque demands of heavy civil jobsites, utilizing a robust 3-cutter head design that maintains speed even when the aggregate gets tough. The 22-inch reach eliminates the need for extensions in most standard wall and slab penetrations, while the high-volume sloped flutes ensure that spoils are cleared efficiently, preventing the heat buildup and binding that plague standard bits in deep-hole applications.\u003c\/p\u003e\n\n\u003cul style=\"list-style: none;
