This 1-1\/2\" x 22\" SDS Max Tunnel Bit is engineered for the heavy civil sector, where deep-hole drilling requires consistent speed and structural integrity. Unlike standard core bits that require constant clearing of the core, the high-volume sloped flutes on this one-piece bit keep dust moving out of the hole continuously, preventing heat buildup and friction. The 3-cutter geometry and carbide centering tip ensure your start is dead-on, even when the surface is uneven, while the rebar chamfers allow you to shear through steel without sacrificing the bit's life or causing tooth fracture.\u003c\/p\u003e\u003cul style=\"list-style: none;
