Milwaukee 12" Quik-Lok Extension 7/16" Hex 48-28-4006
MAXIMIZE REACH AND TORQUE TRANSFER FOR HEAVY-DUTY DRILLING
When navigating deep joist bays or stacked headers, standard bit lengths often fall short of the mark. This 12-inch Quik-Lok extension is engineered to bridge that gap, providing the necessary reach for large-diameter drilling while maintaining the structural integrity needed for high-torque applications. The 7/16" hex shank is specifically designed to handle the aggressive rotational forces generated by selfeed bits and hole saws, ensuring that power from the motor is efficiently transferred to the cutting edge without slipping in the chuck.
- / 12-Inch Extended Reach: Provides the critical clearance required for drilling through deep structural members or multiple studs in a single pass.
- / Quik-Lok™ Rapid Release: Features a fast, tool-free bit change mechanism that accepts 7/16" hex shanks, significantly reducing downtime between holes.
- / High-Torque 7/16" Hex Shank: Engineered for use in 1/2" or larger 3-jaw chucks and 7/16" quick-change chucks, preventing bit slippage under heavy loads.
- / Universal Accessory Compatibility: Optimized for selfeed bits, auger bits, and hole saws 1-inch in diameter and larger.
