Cobalt high-speed steel construction provides superior heat resistance and hardness retention, making this bit well-suited for drilling stainless steel, cast iron, hard alloys, and other difficult-to-machine materials. The stub-length body offers increased rigidity compared to jobber-length bits, reducing deflection and improving hole accuracy in tight setups. Licensed machinists, tool-and-die technicians, and maintenance professionals reach for this type of bit when standard HSS tooling falls short.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in machine tool applications including drill presses, CNC machining centers, turret lathes, and manual mills. The 1\/2 inch shank allows it to seat in standard 1\/2 inch chucks and collet systems without requiring a special adapter for most setups. It is a practical choice for production shops, maintenance departments, and fabrication environments where accurate, repeatable holes in hard or abrasive materials are required on a regular basis.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e51\/64 inch cutting diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction resists heat and wear in hard materials\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch reduced shank fits standard drill press and machine tool chucks\u003c\/li\u003e\n  \u003cli\u003eStub-length body provides extra rigidity and reduces bit deflection\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or upgrade for 51\/64 inch stub-length drill bits used in 1\/2 inch chuck machine tool applications. No specific OEM compatibility data was provided; confirm shank and length requirements against your machine tool specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or qualified maintenance technicians. Always ensure the machine is fully powered down and the spindle is at rest before inserting or removing the bit from the chuck. Secure the shank firmly in the chuck to the full depth of the jaws to prevent slippage under cutting load. Use appropriate cutting fluid or coolant for the workpiece material 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: 51\/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 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\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: C1080-051-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233536737586,"sku":"C1080-051-D","price":65.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620381.png?v=1780102535","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c1080-051-d-cobalt-drill-bit-51-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
