The 1-1\/16-inch cutting diameter pairs with a 1\/2-inch straight shank, making it compatible with standard drill chucks found on drill presses, milling machines, and heavy-duty hand drills. The cobalt construction provides superior heat resistance compared to standard high-speed steel, allowing the bit to maintain a sharp cutting edge under high-speed, high-feed conditions common in metalworking and fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shops, fabrication facilities, and industrial maintenance environments where stub-length drills are preferred for their rigidity and reduced deflection. The shorter flute length of the screw machine style improves stability when drilling through thick stock or when working in tight clearance situations. It is typically installed and used by machinists, tool-and-die technicians, pipefitters, and maintenance mechanics who require consistent hole quality in demanding materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for improved heat resistance and longer tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length design reduces deflection and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003e1-1\/16-inch cutting diameter for large-bore drilling applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eSuitable for drilling hardened steel, stainless steel, cast iron, and similar hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard addition for any drill press, milling machine, or heavy-duty drill equipped with a 1\/2-inch or larger chuck capacity.

Use appropriate cutting fluid or coolant when drilling hard metals to extend tool life and improve hole finish. Always wear proper eye protection and secure the workpiece with a vise or clamps. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection.\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\/16 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\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\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: C1090-104-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51234025013554,"sku":"C1090-104-I","price":66.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620620.png?v=1780115419","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-104-i-cobalt-drill-bit-1-1-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
