It features a 2-1\/16 inch saw diameter and a 1-1\/2 inch cutting depth, making it suited for a range of trade applications including HVAC, plumbing, and electrical rough-in work. The toothed cutting edge with a variable pitch pattern improves chip clearance and reduces binding during cuts. A 1\/2 inch arbored shank provides a secure, positive connection to standard drill arbors. This saw is installed and used by licensed tradespeople who need a reliable, repeatable hole size in sheet metal, conduit boxes, and similar substrates.\u003c\/p\u003e\u003cp\u003eThe LENOX 1772780 is well suited for residential and light commercial work where consistent 2-1\/16 inch holes are required in metal. Typical applications include punching holes in electrical enclosures, HVAC sheet metal panels, and plumbing rough-in scenarios. The variable pitch tooth geometry helps manage heat buildup and extends blade life when working through ferrous and non-ferrous metals. It is sold as a single unit and is ready to mount on a compatible 1\/2 inch arbor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-1\/16 inch saw diameter for precise, repeatable hole sizing\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch cutting depth accommodates standard panel and sheet metal thicknesses\u003c\/li\u003e\n\u003cli\u003eBi-metal construction combines high-speed steel teeth with a flexible alloy steel back for durability\u003c\/li\u003e\n\u003cli\u003eVariable pitch toothed edge reduces vibration and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003e1\/2 inch arbored shank for secure connection to standard drill arbors\u003c\/li\u003e\n\u003cli\u003eOptimized for metal material applications including ferrous and non-ferrous stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2 inch hole saw arbors compatible with bi-metal hole saws.

Before use, secure the workpiece firmly and ensure the drill and arbor are rated for the saw diameter. Allow the saw to reach cutting speed before applying full pressure to the workpiece, and back off periodically to clear chips and reduce heat buildup. Follow applicable safety codes and wear appropriate eye and hand protection during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 2-1\/16 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\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\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112826\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1772780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOX","offers":[{"title":"Default Title","offer_id":51543365779762,"sku":"1772780","price":34.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2be86aae768083cb2ad15d6796b48127.jpg?v=1785917227","url":"https:\/\/voomisupply.com\/products\/lenox-1772780-bi-metal-hole-saw-2-1-16-in-metal-cutting","provider":"Voomi Supply","version":"1.0","type":"link"}
