Built around a 3.5 TPI tooth geometry, this hole saw delivers extended blade life in metal while maintaining versatility across a range of materials. A thermoset coating reduces friction during the cut, which translates to faster cutting speeds and optimized performance on cordless tools. Licensed tradespeople and experienced installers working in electrical, HVAC, plumbing, and construction trades rely on this style of hole saw for precise, repeatable through-cuts in metal panels, junction boxes, pipe penetrations, and similar tasks.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for residential and commercial job-site use wherever a 4-3\/4 inch diameter hole is required. The all-access slots along the body allow straightforward plug removal without additional tools, reducing downtime between cuts. The slot design also improves pilot bit visibility for accurate hole placement and promotes faster chip ejection, helping keep cut temperatures lower during extended use. Sold as a package of 2 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.5 TPI tooth design engineered for extended life in metal applications\u003c\/li\u003e\n\u003cli\u003eThermoset coating reduces friction and is optimized for cordless tool use, delivering more holes per battery charge\u003c\/li\u003e\n\u003cli\u003eAll-access slots simplify plug removal and improve pilot visibility for accurate placement\u003c\/li\u003e\n\u003cli\u003eFaster chip ejection helps manage heat buildup during continuous cutting\u003c\/li\u003e\n\u003cli\u003eCompatible with arbors TV 138-923 and TV 139-793\u003c\/li\u003e\n\u003cli\u003ePackage includes 2 hole saws per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with arbors TV 138-923 and TV 139-793 as stated by the manufacturer.
