Milwaukee 49-56-0247 Bi-metal Hole Saw 5.5 Inches

Product Description

The Milwaukee Electric Tool Corp 49-56-0247 is a 5.5-inch bi-metal hole saw designed for cutting clean, accurate holes in a wide range of materials. Bi-metal construction combines a high-speed steel cutting edge with a durable alloy steel body, giving it the hardness needed to cut through wood, plastics, drywall, and light-gauge metals. This hole saw is a standard tool for electricians, plumbers, HVAC technicians, and general contractors who need consistent, repeatable hole quality during rough-in and installation work. The 5.5-inch diameter makes it well suited for larger penetrations such as pipe pass-throughs, junction box cutouts, and duct openings.

This hole saw is used across residential and light commercial jobsites wherever a 5.5-inch diameter penetration is required. Common applications include cutting pipe and conduit openings through framing, subflooring, and wall assemblies. HVAC installers use this size for duct collar cutouts and equipment knock-outs. Plumbers and electricians reach for it during rough-in when precise, clean-edged holes are needed through wood and composite materials. It is sold individually and is compatible with standard arbor systems used on corded and cordless drills and hole saw kits.

Installation Notes

Installation of this hole saw is performed by licensed electricians, plumbers, and HVAC technicians during rough-in phases. Secure the arbor and hole saw assembly firmly to the drill chuck before use, and verify the pilot bit is properly seated. Always wear eye protection and secure the workpiece before cutting. Follow applicable NEC, IPC, or IFGC penetration and fire-blocking requirements when cutting through rated assemblies.
