Milwaukee 2-1/2" X 22" One Piece SDS Max Tunnel Bit

DOMINATE DEEP PENETRATIONS IN REINFORCED CONCRETE

When you're punching through structural slabs or thick foundations, you can't afford a bit that chokes on rebar or requires constant clearing. 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.

• / 3-Cutter Carbide Centering Tip provides pinpoint accuracy for precise starts and rapid grinding through high-PSI concrete.
• / Rebar Chamfers on the carbide teeth prevent chipping and tooth breaks when encountering structural steel reinforcement.
• / High-Volume Sloped Flutes maximize dust extraction, keeping the hole clear for faster penetration and reduced heat buildup.
• / Alternating Carbide Geometry ensures aggressive shearing through tough aggregates and rebar-heavy pours.
• / 22" One-Piece Shaft Design allows for deep-hole drilling without the mechanical failure points of multi-piece systems.
