It features a 4-inch saw diameter and a 1.5-inch cutting depth, making it well suited for electrical, plumbing, and HVAC rough-in work where clean, accurate holes are required. The toothed cutting edge uses a variable pitch pattern that reduces vibration and blade grab during cut progression. The arbored design accepts a standard 0.5-inch shank arbor, allowing fast chucking in most drill drivers and drill presses used on the job.\u003c\/p\u003e\u003cp\u003eThis hole saw is intended for cutting metal substrates in both residential and commercial service applications. Electricians, HVAC technicians, and plumbers commonly use this size when routing conduit, pipe, or refrigerant line sets through metal studs, panels, and junction boxes. The 4-inch diameter is a frequently specified size for larger conduit knockouts and pipe penetrations. The bi-metal construction handles the repeated stress of production-rate drilling without the early tooth fatigue seen in carbon-steel-only blades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch saw diameter sized for large conduit and pipe penetrations\u003c\/li\u003e\n\u003cli\u003e1.5-inch cutting depth accommodates standard metal panel and stud thicknesses\u003c\/li\u003e\n\u003cli\u003eBi-metal construction for extended tooth life on metal substrates\u003c\/li\u003e\n\u003cli\u003eVariable pitch toothed edge reduces vibration and minimizes blade grab\u003c\/li\u003e\n\u003cli\u003eArbored design with 0.5-inch shank diameter fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard arbored hole saw for use with compatible 0.5-inch shank arbors on drill drivers and drill presses; confirm arbor compatibility before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed electricians, HVAC technicians, or plumbers depending on the application. Secure the workpiece before drilling and ensure the drill is set to an appropriate speed for metal cutting. Always wear eye protection and appropriate PPE when operating hole saws on metal. Inspect the blade for cracked or missing teeth before each use and replace if damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1.5 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: 0.5 inches\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\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: 1773002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOX","offers":[{"title":"Default Title","offer_id":51539247006002,"sku":"1773002","price":52.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fbdc275c048c4683fda2db770e5c3b9.jpg?v=1785837065","url":"https:\/\/voomisupply.com\/products\/lenox-1773002-hole-saw-4-in-bi-metal-variable-pitch","provider":"Voomi Supply","version":"1.0","type":"link"}
