Milwaukee 49-56-9100 Quick Change Hole Saw Arbor

Product Description

The Milwaukee Electric Tool Corp 49-56-9100 is a universal quick-change hole saw arbor designed for tool-free blade swaps in the field. Built from hardened steel, this arbor accepts all brands of hole saws 1-1/4 inches and larger without adapters, making it a practical carry item for electricians, plumbers, and HVAC techs who run multiple hole saw sizes on a single job. The 7/16-inch shank fits all standard 1/2-inch and larger drill chucks. The quick-change mechanism eliminates the need for wrenches when swapping saws, reducing downtime between cuts.

This arbor suits residential and light commercial trade work wherever hole saws are used for cable, conduit, pipe, or duct penetrations. Because it works across brands, technicians can standardize on a single arbor and switch between their existing inventory of hole saw blades without purchasing brand-specific adapters. The tool-free change mechanism is particularly useful on overhead or confined-space work where manipulating small hardware is difficult.
