The toothed cutting edge and variable pitch pattern work together to reduce vibration, minimize heat buildup, and extend blade life during repetitive cutting tasks. At 3-1\/8 inches in diameter and 1-1\/2 inches in cut depth, this saw handles standard trade applications where consistent hole size and depth are critical. The 1\/2-inch arbored shank ensures secure attachment to compatible drill arbors. Licensed HVAC techs, plumbers, and electricians reach for this saw when running pipe, conduit, or duct penetrations through metal panels and framing members.\u003c\/p\u003e\n\u003cp\u003eThis hole saw suits residential and light commercial trade work where metal penetrations are required. Common applications include cutting holes in electrical enclosures, HVAC sheet metal, plumbing access panels, and structural steel framing. The 3-1\/8-inch diameter is a frequently used size for pipe and conduit rough-in work. Its bi-metal construction handles the repeated stress of production cutting without the premature tooth wear common in carbon-steel-only saws.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBi-metal construction for durability and extended cutting life on metal substrates\u003c\/li\u003e\n  \u003cli\u003e3-1\/8-inch saw diameter for standard pipe, conduit, and panel penetrations\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-inch cutting depth accommodates typical panel and framing stock thickness\u003c\/li\u003e\n  \u003cli\u003eVariable pitch tooth pattern reduces vibration and heat during cuts\u003c\/li\u003e\n  \u003cli\u003eToothed cutting edge delivers clean hole profiles with minimal burring\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch arbored shank provides positive engagement with standard drill arbors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-inch hole saw arbors.

Ensure the drill and arbor are powered off and fully stopped before mounting or removing the saw. Use appropriate cutting fluid or lubricant when cutting harder metals to reduce heat and extend tooth life. Follow applicable NEC, IPC, or IFGC clearance and penetration requirements when cutting holes in structural or fire-rated assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Metal\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: 0.5 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: 1772964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOX","offers":[{"title":"Default Title","offer_id":51541254209842,"sku":"1772964","price":48.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa2d4ef432f465d136d132c92940dcac.jpg?v=1785870844","url":"https:\/\/voomisupply.com\/products\/lenox-1772964-bi-metal-hole-saw-3-1-8-in-metal-cutting","provider":"Voomi Supply","version":"1.0","type":"link"}
