It measures 3.25 inches in diameter with a cutting depth of 1.5625 inches, making it suited for punching clean holes through sheet metal, conduit boxes, ductwork panels, and similar materials. The toothed cutting edge follows a variable pitch pattern, which reduces vibration and binding during cuts. The arbored design includes a 0.25-inch shank for secure chuck engagement. Licensed tradespeople and experienced installers reach for this saw when drilling access holes in metal enclosures and housings.\u003c\/p\u003e\n\u003cp\u003eThis hole saw is intended for metal material applications across residential and commercial job sites. It fits common scenarios in HVAC duct penetrations, electrical panel and junction box knockouts, plumbing rough-in through metal framing, and similar trade tasks. The 3-inch pipe tap compatibility makes it directly relevant for tradespeople sizing holes for standard pipe pass-through work. Its compact arbored profile suits both handheld drills and drill press setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.25-inch saw diameter for standard trade hole sizes\u003c\/li\u003e\n  \u003cli\u003eBi-metal construction for durability cutting through metal\u003c\/li\u003e\n  \u003cli\u003eVariable pitch toothed edge reduces vibration and improves cut quality\u003c\/li\u003e\n  \u003cli\u003e1.5625-inch cutting depth handles typical sheet metal and light structural stock\u003c\/li\u003e\n  \u003cli\u003eArbored with a 0.25-inch shank for secure, centered chuck attachment\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3-inch pipe tap sizing for pass-through applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard trade hole saw for metal cutting applications requiring a 3.25-inch diameter opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified tradesperson familiar with rotary cutting tools and applicable safety codes. Secure the workpiece fully before cutting to prevent movement. Use appropriate cutting fluid or lubricant when drilling through heavier gauge metal stock to extend blade life. Inspect the arbor and shank for wear or damage before each use and replace if the cutting edge shows signs of stripping or tooth loss.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Material\u003c\/strong\u003e: Bi-Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Toothed, Variable Pitch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Tap Compatibility\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.78 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: LENOX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1772966\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOX","offers":[{"title":"Default Title","offer_id":51541897347378,"sku":"1772966","price":34.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcb81467fd17688931b8055147b877b6.jpg?v=1785887591","url":"https:\/\/voomisupply.com\/products\/lenox-1772966-bi-metal-hole-saw-3-25-in-metal-cutting","provider":"Voomi Supply","version":"1.0","type":"link"}
