Bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, allowing the saw to resist tooth strippage under load while maintaining a consistent cut. Rated at 300 RPM, this hole saw is designed to cut wood, aluminum, copper, iron, stainless steel, and zinc. Electricians, plumbers, and HVAC technicians commonly reach for this size when cutting knockout holes for conduit, pipe, or drain fittings through framing, panels, and sheet metal.\u003c\/p\u003e\n\u003cp\u003eThe 373118BX suits a wide range of residential and light commercial field applications. The 1-1\/8 inch diameter makes it a standard choice for conduit knockouts, plumbing rough-ins, and sheet metal penetrations. It fits standard arbors compatible with bi-metal hole saws and is sold individually, making it easy to replace a single worn saw without purchasing a full kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBi-metal construction for extended tooth life across hard and soft materials\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch cutting diameter suits common conduit and pipe rough-in applications\u003c\/li\u003e\n  \u003cli\u003eRated at 300 RPM for controlled cutting in metal and wood\u003c\/li\u003e\n  \u003cli\u003eCuts wood, aluminum, copper, iron, stainless steel, and zinc\u003c\/li\u003e\n  \u003cli\u003eSold individually for single-saw replacement without a full kit purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or field-use bi-metal hole saw compatible with standard arbors accepting bi-metal hole saw bodies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this hole saw is performed by electricians, plumbers, and HVAC technicians using a standard drill or hole saw arbor.
