It uses a 3.5 TPI tooth geometry engineered for extended tool life in metal applications. A thermoset coating reduces friction during the cut, which keeps temperatures lower and improves compatibility with cordless tool platforms. The all-access slots built into the cup address one of the most common field complaints with hole saws: plug removal. Faster plug ejection means less downtime between holes on the job. This saw is manufactured in the USA.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for residential and commercial trade work across HVAC, electrical, and plumbing disciplines. Typical applications include cutting conduit knockouts, pipe penetrations through framing or light-gauge metal, and panel openings. The 1-inch cut diameter fits a range of common rough-in and penetration tasks. The all-access slot design also improves pilot bit visibility during placement, which reduces layout errors and the need for repositioning on finished or painted surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.5 TPI tooth design engineered for extended life in metal cutting applications\u003c\/li\u003e\n\u003cli\u003eAll-access slots for faster plug removal and reduced downtime between holes\u003c\/li\u003e\n\u003cli\u003eImproved pilot bit visibility for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eThermoset coating reduces heat buildup and optimizes performance on cordless tools\u003c\/li\u003e\n\u003cli\u003eBi-metal construction for durability across general-purpose materials\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose bi-metal hole saw for use with standard arbors compatible with 1-inch hole saw cups across HVAC, plumbing, and electrical trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed electricians, HVAC technicians, and plumbers using a standard drill or hole saw arbor. Ensure the workpiece is securely clamped before beginning the cut. Disconnect power to any panel or energized surface before cutting nearby.
