Milwaukee 12" Extension for 3/8" Hex Shank Arbors 48-28-4008
DEEP REACH DRILLING FOR MAXIMUM JOBSITE VERSATILITY
Professional-grade hole saw applications often demand more than a standard arbor length can provide, particularly when navigating deep wall cavities or thick floor joists. The Milwaukee 48-28-4008 provides a full 12 inches of additional reach, engineered to maintain concentricity and minimize wobble during high-torque drilling. By utilizing a 3/8-inch hex shank, this extension ensures a positive grip within 3-jawed chucks, eliminating the slippage that often plagues round-shank alternatives. This is a critical accessory for tradesmen looking to maximize their existing hole saw kit's ROI by expanding its capability into deep-reach territory without sacrificing the structural integrity of the cut.
- / 12-inch extended reach allows for drilling through multiple layers or deep structural members.
- / 3/8-inch hex shank design provides a secure, non-slip fit in all standard 3-jawed drill chucks.
- / Universal compatibility with all 3/8-inch hex shank hole saw arbors for seamless integration.
- / Heavy-duty construction maintains rigidity under load to ensure accurate hole placement.
