Cobalt high-speed steel construction provides superior heat resistance and edge retention when drilling through hard or abrasive materials such as stainless steel, cast iron, titanium, and hardened alloys. The stub-length flute design offers increased rigidity over jobber-length bits, reducing deflection and improving hole accuracy in demanding production and maintenance environments. Machinists, tool-and-die workers, and industrial maintenance technicians rely on this style of bit for precision drilling in tight workspaces or on drill press and CNC setups where rigidity is critical.\u003c\/p\u003e\u003cp\u003eThe C1080-043-D is suited for use in general machining, fabrication shops, and industrial maintenance applications where hard or difficult-to-machine materials are common. The 1\/2-inch shank allows it to seat in standard 1\/2-inch keyed or keyless chucks found on drill presses, knee mills, lathes, and compatible CNC equipment. Its stub-length geometry is particularly useful when drilling through thicker stock or when minimizing bit runout is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e43\/64-inch cutting diameter for precise oversized or clearance hole applications\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction resists heat buildup and edge wear on hard materials\u003c\/li\u003e\n\u003cli\u003eStub-length flute design increases rigidity and reduces deflection during drilling\u003c\/li\u003e\n\u003cli\u003e1\/2-inch reduced shank fits standard 1\/2-inch drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eManufactured in the USA to industrial quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2-inch drill chucks on drill presses, milling machines, lathes, and compatible CNC drilling equipment commonly found in machining and fabrication environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank firmly in a properly sized chuck before operation and verify runout before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is clamped securely to prevent movement. Use a suitable cutting fluid for hard materials to extend tool life and improve hole finish. Allow the bit to cool gradually after use — do not quench cobalt tooling in water, as thermal shock can cause micro-cracking.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 43\/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 Series\u003c\/strong\u003e: Stub Length (Screw Machine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C1080-043-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233889845554,"sku":"C1080-043-D","price":55.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620292.png?v=1780111335","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1080-043-d-cobalt-stub-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
