Cobalt construction provides superior heat resistance and edge retention compared to standard high-speed steel, making this bit well-suited for drilling through hard metals, stainless steel, cast iron, and high-tensile alloys. The stub-length flute design increases rigidity and reduces deflection during penetration, which is especially valuable in tight-clearance drilling applications. Licensed machinists, tool-and-die technicians, pipefitters, and industrial maintenance professionals are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in stationary drill presses, CNC machining centers, radial arm drills, and heavy-duty handheld drill motors equipped with 1\/2-inch chucks. The 57\/64-inch diameter is a common size for hole preparation prior to reaming or tapping in metal fabrication and industrial maintenance environments. The 1\/2-inch shank allows the bit to seat securely in standard 1\/2-inch drill chucks without requiring a larger spindle bore, broadening its compatibility across common shop equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e57\/64-inch cutting diameter for precision metal drilling and pre-ream hole prep\u003c\/li\u003e\n  \u003cli\u003eCobalt construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eStub screw machine length reduces deflection and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch reduced shank fits standard 1\/2-inch drill chucks\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for standard 1\/2-inch chuck drill presses, machining centers, and heavy-duty drill motors used in metal fabrication and industrial maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove only with the drill motor fully powered down and the chuck key removed from the area. Secure the shank fully into the chuck and tighten evenly before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and maintain cutting edge integrity. Follow applicable shop safety standards and employer-mandated PPE requirements when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 57\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Style\u003c\/strong\u003e: Screw Machine (Stub Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.69 pounds\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: C1080-057-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233894662450,"sku":"C1080-057-D","price":78.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620386.png?v=1780111465","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1080-057-d-cobalt-drill-bit-57-64","provider":"Voomi Supply","version":"1.0","type":"link"}
