AGGRESSIVE STRUCTURAL PENETRATION FOR DEEP-HOLE CONCRETE DRILLING
When you're pushing through thick structural footings or running large-diameter utility lines through reinforced concrete, you can't afford to get bogged down by dust packing or rebar strikes. 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.
- / 3-Cutter Carbide Centering Tip ensures precise hole placement and prevents walking on hard aggregate or steel.
- / Integrated Rebar Chamfers protect the carbide teeth from fracturing when encountering embedded reinforcement steel.
- / High-Volume Sloped Flutes accelerate dust removal to maintain drilling speed and extend the life of the bit.
- / One-Piece Construction provides maximum energy transfer from the SDS Max rotary hammer to the cutting head.
