Milwaukee Tool 49-57-0010 Hole Saw Arbor Morse Taper

Product Description

The MILWAUKEE TOOL 49-57-0010 is a hole saw arbor designed to connect hole saws to a drill or drill press using a Morse taper shank interface. It accepts hole saws ranging from 1 inch to 6 inches in saw diameter, covering the full range of common trade applications. The round shank cross-section and integrated pin pilot keep the saw centered during entry, reducing wander on metal, wood, and composite substrates. At 2.05 pounds, the arbor is built for repeated use in the field or shop. HVAC technicians, electricians, plumbers, and general contractors rely on this style of arbor when cutting large-diameter holes through framing, panels, and mechanical room substrates.

This arbor is suited for use in residential and light commercial applications where large-format hole cutting is required. Typical scenarios include drilling knockout holes in electrical panels, cutting pipe penetrations through framing or subfloor, and boring duct openings in wood or light-gauge material. The Morse taper shank provides a secure, self-seating connection to compatible drill chucks and arbor-style drill press spindles. The pin pilot design guides the saw during initial contact and helps maintain hole concentricity throughout the cut.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary cutting tools. Ensure the drill or drill press is fully powered down and the chuck is released before seating or removing the arbor. The Morse taper shank should be fully seated before applying load to prevent slippage during cutting. Follow applicable safety standards for rotary tool operation, and wear appropriate eye and hand protection when using hole saws.
