Silver deming bits are designed for drilling large-diameter holes in metal using a standard 1\/2 inch drill chuck, eliminating the need for a large-capacity chuck or Morse taper spindle. The cobalt construction improves heat resistance and edge retention compared to standard high-speed steel, making this bit suitable for harder metals and higher-production drilling cycles. Machinists, maintenance technicians, and fabricators typically reach for this style when drilling through steel plate, cast iron, or stainless steel where a standard twist drill would wear quickly.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for use in drill presses, magnetic base drills, and hand-held heavy-duty drills equipped with a 1\/2 inch chuck. Typical applications include structural fabrication shops, HVAC equipment fabrication, plumbing rough-in work requiring oversized metal penetrations, and general maintenance drilling in industrial and commercial settings. The 1-7\/32 inch diameter is a common size for creating clearance holes and knock-outs in sheet metal enclosures, panels, and light structural steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-7\/32 inch cutting diameter fits oversized hole requirements without a large-capacity chuck\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction provides elevated heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003eReduced 1\/2 inch straight shank is compatible with standard 1\/2 inch drill chucks\u003c\/li\u003e\n  \u003cli\u003eSilver deming geometry allows use in portable drills and bench-top drill presses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 1-7\/32 inch reduced-shank silver deming drill bits used with any drill press or heavy-duty 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 a properly rated drill chuck before operation. Use cutting fluid or a suitable metalworking lubricant when drilling hard or thick metals to reduce heat buildup and extend bit life. Wear appropriate PPE including eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the edge is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-7\/32 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\u003eShank Type\u003c\/strong\u003e: Reduced straight shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt steel\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: C1090-114-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233578254642,"sku":"C1090-114-I","price":79.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620608.png?v=1780103687","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-114-i-cobalt-silver-deming-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
