Cobalt construction gives this bit increased heat resistance and hardness compared to standard high-speed steel, making it suited for drilling into tough materials such as stainless steel, cast iron, hardened alloys, and other hard ferrous metals. The slow spiral geometry promotes efficient chip evacuation and reduces heat buildup during heavy-duty drilling operations. Machinists, tool-and-die technicians, and metal fabricators typically use this size and style on drill presses or milling machines where rigid setups are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is appropriate for industrial and production environments where large-diameter hole making in hard metals is a routine task. The 1\/2-inch shank fits standard drill press chucks and milling machine setups. It is well suited for maintenance, repair, and fabrication applications in manufacturing shops, shipyards, and heavy equipment facilities where tooling must hold up under repeated use and elevated cutting temperatures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt alloy construction for superior heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e1-inch cutting diameter for large-bore hole making in a single pass\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank for compatibility with standard drill press chucks\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute design promotes chip clearing and reduces heat during deep drilling\u003c\/li\u003e\n  \u003cli\u003eImport grade offering a cost-effective option for general production and maintenance use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, milling machines, and magnetic drills equipped with a standard 1\/2-inch chuck or collet.

Secure the 1\/2-inch shank firmly in the chuck before operation and verify that the workpiece is properly clamped. Apply appropriate cutting fluid to reduce heat and extend bit life when drilling hard metals. Inspect the cutting edges for wear before each use and remove the bit from service if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Slow Spiral\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: C1090-100-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233309327666,"sku":"C1090-100-I","price":52.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620613.png?v=1780096995","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-100-i-cobalt-drill-bit-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
