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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.5-inch cutting diameter for larger pipe, conduit, and duct penetrations\u003c\/li\u003e\n\u003cli\u003eBi-metal construction pairs high-speed steel teeth with an alloy steel body for extended cutting life\u003c\/li\u003e\n\u003cli\u003eStandard arbor compatibility works with common drill and hole saw arbor setups\u003c\/li\u003e\n\u003cli\u003eSuited for wood, plastics, drywall, and light-gauge metal cutting tasks\u003c\/li\u003e\n\u003cli\u003eConsistent tooth geometry supports clean hole edges and reduced material tear-out\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard trade hole saw compatible with conventional arbor-drive systems used on corded and cordless drills across residential and light commercial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.
