Built with a 3.5 TPI tooth geometry, this hole saw is engineered for extended tooth life in demanding metal applications. A thermoset coating reduces friction during the cut, which translates to faster cutting speeds and optimized performance on battery-powered tools. All-access slots on the body allow for straightforward plug removal without extra tools, reducing downtime between holes and keeping the pilot bit visible for accurate placement. Licensed contractors, electricians, and plumbers rely on this saw for conduit knockouts, pipe penetrations, and panel work.\u003c\/p\u003e\n\u003cp\u003eThis hole saw is suited for residential and commercial applications where repeated cuts through sheet metal, steel plate, wood framing, or plastic are required. The 3.5 TPI design handles both thin-gauge and thicker stock, making it a practical option for electrical rough-in, plumbing penetrations, and HVAC ductwork. The thermoset coating is specifically optimized for cordless drill and driver use, maintaining cut quality as battery voltage tapers. Compatible arbors include TV 138-923 and TV 139-793 as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.5 TPI bi-metal 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 performance\u003c\/li\u003e\n  \u003cli\u003eAll-access slots enable faster plug removal and improved chip ejection\u003c\/li\u003e\n  \u003cli\u003eIncreased pilot bit visibility through slot design for accurate hole placement\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose bi-metal construction handles metal, wood, and composite materials\u003c\/li\u003e\n  \u003cli\u003eSold as individual unit; package quantity of 24 available per case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with arbors TV 138-923 and TV 139-793 as stated by the manufacturer.
