Milwaukee Tool 49-56-9680 Bi-metal Hole Saw 2-1/4 in

Product Description

The MILWAUKEE TOOL 49-56-9680 is a bi-metal hole saw designed for cutting through metals in trade and industrial applications. It carries a 2.25-inch saw diameter and a 1.625-inch cutting depth, making it well-suited for drilling clean, accurate holes in sheet metal, conduit boxes, steel panels, and similar ferrous and non-ferrous substrates. The toothed cutting edge delivers consistent bite and chip clearance through the cut. The 0.375-inch arbored shank provides a secure, centered connection to standard drill chucks and compatible arbors. This saw is built for electricians, plumbers, HVAC technicians, and pipefitters who need reliable hole saw performance on metal work.

This hole saw is intended for metal cutting applications in both residential and commercial service environments. Typical use cases include punching knockout holes in electrical enclosures, cutting access ports in metal HVAC plenums, and drilling through steel or aluminum panels during rough-in work. The arbored design means it mounts directly to a compatible arbor without the need for a separate pilot drill assembly, streamlining setup on the job site.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary cutting tools and applicable safety standards. Ensure the drill or driver is powered off and the bit is fully secured in the arbor before operation. Use appropriate cutting fluid or lubricant when cutting harder metals to extend blade life and reduce heat buildup. Eye protection and gloves are recommended during all hole saw operations.
