With a 4-3\/4 inch saw diameter and a 1-5\/8 inch cutting depth, this saw handles a wide range of through-hole and penetration tasks encountered in HVAC, plumbing, and electrical rough-in work. The constant-pitch tooth pattern at 5.5 teeth per inch (TPI) delivers consistent chip evacuation and reduces blade deflection during the cut. Built from high speed steel, the saw maintains edge integrity through repeated cuts in demanding materials without frequent resharpening.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for residential and light commercial trade applications where accurate, repeatable hole sizing is required. HVAC technicians use it for duct penetrations and equipment knockouts. Plumbers rely on it for pipe pass-throughs in wood framing and light-gauge metal. Electricians reach for it when pulling conduit or mounting junction boxes through metal panels or stud bays. The 4-3\/4 inch diameter is a common size for larger conduit runs, drain line clearances, and HVAC duct collars.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-3\/4 inch saw diameter for large-bore penetration work in metal, steel, and wood\u003c\/li\u003e\n\u003cli\u003e1-5\/8 inch cutting depth accommodates standard framing lumber and light metal panel stacks\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction maintains cutting edge through repeated use on hard materials\u003c\/li\u003e\n\u003cli\u003eConstant-pitch tooth pattern at 5.5 TPI provides smooth, consistent chip removal\u003c\/li\u003e\n\u003cli\u003eToothed cutting edge style for efficient material removal without pilot-hole tearing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use hole saw compatible with standard arbor systems accepting 4-3\/4 inch bi-metal or HSS hole saws commonly used in HVAC, plumbing, and electrical trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed electrician, plumber, or HVAC technician should confirm hole placement against local code requirements before cutting. Always power down or de-energize any panel or equipment in the work area before drilling penetrations near live conductors or pressurized lines. Use an appropriate arbor and pilot bit rated for this saw diameter, and secure the workpiece firmly to prevent binding. Allow the saw to cool between cuts when working through hard steel to preserve tooth life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 4-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1-5\/8 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\u003eTeeth Per Inch\u003c\/strong\u003e: 5.5 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Constant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Metal, Steel, Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.8 inches x 4.8 inches x 1.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 00531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542008955186,"sku":"00531","price":91.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d6a5f329531dbbfb82e7b35d9bb71ff.jpg?v=1785889439","url":"https:\/\/voomisupply.com\/products\/starrett-00531-hole-saw-4-3-4-in-hss-metal-wood","provider":"Voomi Supply","version":"1.0","type":"link"}
