At 11\/64 inches in diameter, this bit uses a RED HELIX geometry that promotes faster chip ejection and reduced heat buildup during extended drilling cycles. The cobalt construction provides increased hardness and heat resistance compared to standard HSS bits, making it suitable for stainless steel, cast iron, and other hard ferrous metals. Each package contains 5 bits, providing working stock for busy service trucks and shop environments. Trade professionals across mechanical, plumbing, and electrical disciplines keep these on hand for everyday metal fabrication and equipment installation tasks.\u003c\/p\u003e\u003cp\u003eThis cobalt drill bit is suited for drilling through hard metals encountered in commercial and residential installation work, including sheet metal, structural steel, and hardware. The 11\/64 inch diameter is a commonly used size for pilot holes, clearance holes, and fastener preparation in light to medium gauge metal stock. The 5-piece pack format supports job-site use where bit replacement is a routine part of workflow rather than an exception.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for increased hardness and heat resistance in hard-metal drilling\u003c\/li\u003e\n\u003cli\u003eRED HELIX geometry promotes efficient chip evacuation and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003e11\/64 inch diameter for pilot holes and fastener clearance in metal stock\u003c\/li\u003e\n\u003cli\u003e5-piece pack provides job-site working stock\u003c\/li\u003e\n\u003cli\u003eSold as individual unit of measure (EA) containing 5 bits per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 11\/64 inch cobalt drill bit compatible with any drill chuck accepting that shank diameter, including standard 3\/8 inch and 1\/2 inch keyed or keyless drill chucks used in corded and cordless drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCobalt drill bits should be installed by confirming the chuck is fully tightened before operation and that the workpiece is securely clamped. Use appropriate cutting fluid or lubricant when drilling stainless steel or hardened alloys to extend bit life. Operate at lower RPM settings for harder materials to prevent premature tip degradation. Wear appropriate PPE including eye protection when drilling metal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: Milwaukee Electric Tool Corp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-89-2308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51524616028466,"sku":"48-89-2308","price":30.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9e8bcbea7a2ed87d8bbeb0474d0f781.jpg?v=1785453170","url":"https:\/\/voomisupply.com\/products\/milwaukee-48-89-2308-cobalt-drill-bit-11-64-in-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
