It features a 3.5 TPI tooth geometry designed to extend tooth life in metal applications. A thermoset coating on the blade reduces friction during the cut, which translates to faster cutting speeds and improved performance when running on cordless tools. All-access slots are machined into the body to simplify plug removal, reduce downtime between holes, and improve pilot bit visibility for accurate placement. Chip ejection is enhanced by the slot design, helping keep the cut zone cooler during extended use.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for general-purpose applications across residential and commercial jobsites. Electricians, plumbers, HVAC technicians, and general contractors use this size to cut chase openings, conduit penetrations, and service access holes in sheet metal, wood framing, and similar materials. The 1-inch diameter makes it a common choice for single-trade rough-in work where a compact, clean-bore hole is required. It is optimized for use with cordless drills and drivers, and the thermoset coating is specifically formulated to deliver consistent performance per battery charge.\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\u003eThermoset coating reduces friction and is optimized for cordless tool use\u003c\/li\u003e\n\u003cli\u003eAll-access slots allow fast plug removal and reduce downtime between holes\u003c\/li\u003e\n\u003cli\u003eSlot design improves pilot bit visibility for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eEnhanced chip ejection keeps cut temperatures lower during continuous use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Arbor TV 138-921 and TV 145-615 as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis hole saw is installed by licensed tradespeople including electricians, plumbers, and HVAC technicians using a compatible arbor and drill or driver.
