With a 3-inch saw diameter and a 2-inch cutting depth, this saw handles a wide range of rough-in and service work where a clean, full-depth hole is required. The toothed cutting edge runs a variable pitch pattern of 4 to 6 teeth per inch, which reduces vibration and helps clear chips efficiently during the cut. It is used by HVAC technicians, plumbers, electricians, and general contractors who need reliable hole saws for panel knockouts, pipe penetrations, and conduit routing.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for both residential and light commercial applications. The variable pitch tooth pattern makes it effective on metal sheet goods, structural steel, and wood framing or sheathing. It is a practical choice when a single saw needs to handle mixed-material cuts on a job site without swapping tools. The 3-inch diameter is a common size for pipe sleeve openings, electrical junction work, and HVAC duct collar penetrations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch saw diameter for common pipe and conduit penetration sizes\u003c\/li\u003e\n\u003cli\u003e2-inch cutting depth handles typical wall and panel thicknesses\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability on metal and wood\u003c\/li\u003e\n\u003cli\u003eVariable pitch 4 to 6 teeth per inch reduces vibration and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eToothed cutting edge for clean, repeatable cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement hole saw compatible with standard arbors accepting 3-inch hole saw bodies across residential and commercial trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by HVAC technicians, plumbers, and electricians using a compatible hole saw arbor and a corded or cordless drill or drill press. Secure the workpiece before cutting and use appropriate cutting fluid when working through steel to extend blade life. Always wear eye protection and ensure the work area is clear of energized conductors or pressurized lines before cutting. Follow applicable NEC, IPC, or IFGC clearance requirements when making penetrations through structural or fire-rated assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 3 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 00453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543536795954,"sku":"00453","price":36.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59abe1ead373dca93c169a8032ba5440.jpg?v=1785920056","url":"https:\/\/voomisupply.com\/products\/starrett-00453-hole-saw-3-in-hss-variable-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
