Cobalt construction provides superior heat resistance compared to standard high-speed steel, making it well suited for prolonged drilling cycles in tough metals. The stub length geometry delivers increased rigidity and reduced deflection relative to jobber-length bits. Electricians, pipefitters, machinists, and general trade professionals use this bit in standard drill presses and heavy-duty hand drills equipped with 1\/2 inch chucks.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for metal fabrication, HVAC, plumbing, and electrical trade applications where accurate, clean holes are required in steel, stainless steel, cast iron, and similarly hard materials. The 1\/2 inch straight shank allows use in any drill press or portable drill with a 1\/2 inch chuck capacity. It is equally suited for production shop environments and field service work where a short, stiff drill profile is preferred for hole accuracy and tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e59\/64 inch cutting diameter for close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eCobalt construction for extended tool life in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003eStub length body provides added rigidity and reduces bit deflection\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight reduced shank fits standard drill press and hand drill chucks\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any drill press or hand drill equipped with a 1\/2 inch chuck.

Secure the 1\/2 inch shank firmly in the chuck before operation and verify the workpiece is clamped to prevent movement. Use appropriate cutting fluid when drilling hard or stainless steel to extend bit life and maintain hole quality. Follow applicable shop safety standards and wear proper eye protection during all drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 59\/64 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 Type\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: 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: C1090-059-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233515438386,"sku":"C1090-059-I","price":49.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620623.png?v=1780101937","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1090-059-i-cobalt-drill-bit-59-64","provider":"Voomi Supply","version":"1.0","type":"link"}
