Cobalt high-speed steel construction provides increased heat resistance and hardness retention compared to standard HSS, making it suitable for drilling stainless steel, cast iron, hard alloys, and other tough materials. The stub-length body offers greater rigidity and reduced deflection, which is critical when drilling in confined spaces or on manual and CNC machine setups. At 0.69 pounds, the bit is a solid, production-grade tool suited for machinists, fabricators, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThe C1090-057-I is designed for use in drill presses, milling machines, and CNC machining centers where a 1\/2-inch chuck or collet is available. The screw machine length is the preferred format in production environments and heavy fabrication shops where hole accuracy and tool life under repeated use are priorities. Typical applications include metalworking, structural fabrication, and maintenance drilling in industrial and commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e57\/64-inch cutting diameter in a stub-length screw machine profile for added rigidity\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for heat resistance and durability in hard metals\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch reduced shank fits standard drill press chucks and CNC tool holders\u003c\/li\u003e\n  \u003cli\u003eStub-length design minimizes deflection and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eProduction-grade construction suited for repeated use in shop and field environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any drill press, milling machine, or machining center equipped with a 1\/2-inch chuck, collet, or tool holder.

Ensure the shank is fully seated and securely clamped in the chuck or collet before operation. Always wear appropriate eye and face protection when operating drill equipment. Use cutting fluid or coolant when drilling hard or heat-sensitive materials to extend tool life and maintain hole quality.\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 High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.69 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: C1090-057-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233995784498,"sku":"C1090-057-I","price":49.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620625.png?v=1780114397","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-057-i-cobalt-drill-bit-57-64","provider":"Voomi Supply","version":"1.0","type":"link"}
