With a 1-inch bit diameter and a 3\/16-inch cutting depth, it handles stainless steel, structural steel studs, brass, aluminum, and other thin sheet materials. The carbide tip maintains cutting performance across these harder materials where standard bi-metal hole saws wear prematurely. This cutter is rated for materials up to 3\/16 inch thick and is compatible with hand-held drills, delivering hole quality comparable to a drill press setup when used correctly.\u003c\/p\u003e\u003cp\u003eThis annular cutter is suited for HVAC, mechanical, and sheet metal trades where repetitive hole cutting in stainless or structural steel is required. Typical applications include cutting holes in steel studs, ductwork flanges, and metal framing components. It is equally effective on non-ferrous sheet materials such as brass and aluminum, making it a versatile addition to a sheet metal installer or mechanical contractor's tool kit. Use with the Milwaukee quick-change arbor 49-57-0035 for fast bit swaps on the job site. Lubrication during drilling is strongly recommended to extend carbide tip life. Milwaukee recommends Hawg Wash cutting fluid, available as part number 49-32-0081, which mixes to produce one gallon of lubricating solution per 16-ounce bottle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch bit diameter for consistent, clean hole sizing in sheet metal\u003c\/li\u003e\n\u003cli\u003e3\/16-inch cutting depth rated for materials up to 3\/16 inch thick\u003c\/li\u003e\n\u003cli\u003eCarbide-tipped construction for extended life in stainless steel and structural steel studs\u003c\/li\u003e\n\u003cli\u003eCompatible with quick-change arbor 49-57-0035 for fast tool changes\u003c\/li\u003e\n\u003cli\u003eUsable in hand-held drills with drill press quality results\u003c\/li\u003e\n\u003cli\u003eEffective on brass, aluminum, and other thin sheet materials in addition to steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Milwaukee quick-change arbor 49-57-0035.

Always ensure the workpiece is secured before beginning the cut and apply cutting fluid throughout the drilling operation to protect the carbide tip. Disconnect or de-energize any adjacent electrical systems before drilling into metal framing or structural members. Do not operate without the recommended arbor, and inspect the carbide tip for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Material Thickness\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-57-8311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51344692576562,"sku":"49-57-8311","price":51.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310513209.jpg?v=1782040582","url":"https:\/\/voomisupply.com\/products\/milwaukee-49-57-8311-carbide-annular-cutter-1-inch-sheet-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
