Cobalt construction gives this bit the heat resistance and hardness needed to cut through tough materials including stainless steel, cast iron, high-nickel alloys, and hardened steel. The jobber-length flute geometry balances reach and rigidity, making it a reliable choice for production drilling, maintenance shops, and job-site use. Machinists, pipefitters, ironworkers, and maintenance technicians reach for cobalt bits when standard high-speed steel bits wear prematurely or overheat under sustained cutting loads.\u003c\/p\u003e\n\u003cp\u003eThis bit fits standard 3-jaw drill chucks and is suited for both handheld and drill-press applications. The 31\/64-inch diameter is commonly used for clearance holes, pilot holes ahead of tapping, and dimensional drilling in fabrication and mechanical work. Its USA manufacture supports consistent metallurgical quality and dimensional tolerance, which matters in production environments where bit-to-bit consistency affects cycle time and tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for superior heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e31\/64-inch diameter for precise clearance and tapping applications\u003c\/li\u003e\n  \u003cli\u003eJobber-length flute design balances reach with torsional rigidity\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA for consistent metallurgical quality\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard 3-jaw drill chucks on handheld drills and drill presses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use cobalt jobber drill bit compatible with any 3-jaw drill chuck accepting a 31\/64-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the bit fully in the chuck and verify chuck key is removed before operation. Use cutting fluid or lubricant when drilling stainless steel, high-nickel alloys, or other hard metals to reduce heat buildup and extend bit life. Allow the bit to cool between extended drilling operations to prevent annealing of the cobalt flutes. Inspect the cutting edges regularly and replace the bit when wear causes overheating or dimensional drift.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 31\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Type\u003c\/strong\u003e: Jobber Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\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: 1.2 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: C300-031-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233698939186,"sku":"C300-031-D","price":23.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620630.png?v=1780107016","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c300-031-d-cobalt-jobber-drill-31-64","provider":"Voomi Supply","version":"1.0","type":"link"}
