Milwaukee 18 in. Quik-Lok Extension 7/16 in. Hex 48-28-4011
MAXIMUM REACH FOR HIGH-TORQUE ROUGH-IN APPLICATIONS
When deep-hole drilling through multiple studs or reaching into tight floor joists, the Milwaukee 48-28-4011 provides the critical 18-inch clearance required for heavy-duty mechanical rough-ins. Engineered for the professional who demands zero-slip performance, this extension features a 7/16-inch hex shank designed specifically to handle the high-torque output of Super Hawgs and large-capacity 1/2-inch drills. The Quik-Lok system ensures that your Selfeed bits, augers, or hole saws remain locked under load, eliminating the risk of bits detaching behind finished surfaces or inside deep wall cavities.
- / 18-inch extended reach for drilling through deep framing and multi-layered structural members.
- / 7/16-inch Quik-Lok hex shank allows for rapid, tool-free bit changes while maintaining maximum grip.
- / Universal compatibility with 1/2-inch 3-jaw chucks and 7/16-inch quick-change systems.
- / Optimized for high-torque accessories including Selfeed bits and hole saws 1-inch and larger.
