It uses a toothed edge with a variable pitch of 4 to 6 teeth per inch, which reduces harmonic vibration and helps prevent tooth stripping during aggressive cuts. This saw is suited for trades that regularly cut through metal, steel, and wood, including HVAC technicians cutting duct penetrations, electricians cutting knockout holes, and plumbers sizing pipe pass-through openings. The HSS construction handles the heat generated during repeated cuts better than carbon steel alternatives.\u003c\/p\u003e\n\u003cp\u003eThis hole saw fits common trade applications where a mid-size diameter opening is needed through sheet metal, light structural steel, or wood framing. Typical uses include cutting holes for conduit, pipe sleeves, duct connections, and access panels. At 2 inches of cutting depth, it handles most single-layer material thicknesses encountered in residential and light commercial service work. It is sold as a single saw body and requires a compatible arbor for use with a drill or drill press.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.5-inch saw diameter for mid-size penetration cuts in metal and wood\u003c\/li\u003e\n  \u003cli\u003e2-inch cutting depth accommodates most single-layer structural materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction resists heat buildup during extended use\u003c\/li\u003e\n  \u003cli\u003eVariable pitch toothed edge (4 to 6 TPI) reduces vibration and tooth stripping\u003c\/li\u003e\n  \u003cli\u003eCompatible with metal, steel, and wood material applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement-style hole saw body compatible with common arbor systems used in trade drill applications.

Secure the workpiece before cutting and wear eye and hand protection. Follow applicable codes such as NEC or IFGC when sizing penetrations through fire-rated or structural assemblies. Allow the saw body to cool between cuts to preserve tooth set and HSS temper.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Toothed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 4 to 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Metal, Steel, Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542975349042,"sku":"00454","price":36.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88de0cfc62d52bcfe1039bcb90fb53bc.jpg?v=1785912837","url":"https:\/\/voomisupply.com\/products\/starrett-00454-hole-saw-3-5-in-hss-variable-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
