Milwaukee QUIK-LOK™ Arbor Adapters Large Thread (5/8" x 18) 5 Pieces 49-56-7571 + (5) FREE Quick Change Hole Saw Arbor 49-56-8000

MAXIMIZE HOLE SAW VERSATILITY WITH RAPID QUIK-LOK™ ADAPTABILITY

Efficiency on the jobsite is often measured by the seconds saved between cuts. The Milwaukee 49-56-7571 QUIK-LOK™ Large Thread Adapters are engineered to eliminate the mechanical friction of traditional arbor changes, allowing for seamless transitions between hole saw diameters. By utilizing a universal 5/8" x 18 thread, these adapters bridge the gap between your existing inventory of industry-standard hole saws and the high-speed productivity of the QUIK-LOK™ system. Designed specifically for the 1-1/4" to 2" range, these adapters provide a high-torque connection that prevents binding and ensures concentric rotation for cleaner, more accurate apertures in wood, metal, and plastic.

• / Universal 5/8" x 18 thread allows for total compatibility with all industry-standard threaded hole saws.
• / Optimized for hole saws ranging from 1-1/4" to 2" to ensure maximum stability during high-speed drilling.
• / Tool-free QUIK-LOK™ integration enables rapid saw changes, significantly reducing downtime on multi-size rough-ins.
• / Durable steel construction maintains thread integrity even under the thermal stress of heavy-duty metal cutting.

HIGH-TORQUE ENGAGEMENT FOR LARGE DIAMETER HOLE SAWS

When driving hole saws 1-1/4 in. and larger, the mechanical interface between the drill and the saw is the most critical failure point. This 7/16 in. hex shank arbor is engineered to eliminate chuck slippage while providing a robust platform for high-torque transmission. The integrated push-pin system locks directly into the hole saw's backing plate, ensuring that the motor's power is transferred efficiently without stripping threads or binding under heavy load. Constructed from hardened steel, this arbor features a tool-free operation that streamlines bit changes, while the hollow shank design allows for immediate pilot bit access and adjustment, maximizing professional ROI through reduced downtime.

• / 7/16 in. Hex Shank provides superior grip in 1/2 in. chucks to prevent slippage during high-load drilling in wood and metal.
• / Push-Pin Locking Mechanism engages the backing plate for positive torque transmission and easier saw removal after heavy use.
• / Universal Quick-Change Design works with all major brands of hole saws 1-1/4 in. and larger without requiring separate adapters.
• / Durable Hardened Steel Construction ensures long-term reliability and resistance to deformation in demanding jobsite environments.
