Cobalt construction gives the cutting edge greater heat resistance than standard high-speed steel, making it well suited for drilling hard and abrasive materials without rapid edge breakdown. The reduced 1\/2 inch shank allows use in standard drill chucks without requiring oversized spindle tooling. This bit is intended for professional machinists, fabricators, and tradespeople working in metal fabrication, maintenance, and general industrial drilling applications.\u003c\/p\u003e\n\u003cp\u003eThe C1090-116-I is used in stationary drilling operations on drill presses and milling machines as well as heavy-duty hand drilling setups where a 1\/2 inch chuck is available. It is suited for drilling ferrous metals including steel, cast iron, and stainless steel, and performs in both production shop environments and field maintenance situations where aggressive material removal is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt alloy construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch cutting diameter for large-bore through-holes in a single pass\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch reduced shank fits standard 1\/2 inch drill chucks and tooling\u003c\/li\u003e\n  \u003cli\u003eSlow spiral geometry promotes chip clearance in deep-hole drilling applications\u003c\/li\u003e\n  \u003cli\u003eSuitable for ferrous metals and hard abrasive materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use large-diameter cobalt drill bit for use in any drill press, milling machine, or portable drill accepting a 1\/2 inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the 1\/2 inch shank firmly in the drill chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling hard ferrous materials to extend tool life and improve cut quality. Always wear appropriate PPE including eye protection when operating rotary cutting tools. Follow machine manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material and drill diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-1\/4 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\u003eMaterial\u003c\/strong\u003e: Cobalt alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C1090-116-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233571209522,"sku":"C1090-116-I","price":83.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620607.png?v=1780103482","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-116-i-cobalt-drill-bit-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
