Cobalt construction provides added heat resistance and hardness compared to standard high-speed steel, making this bit suitable for drilling into harder materials such as stainless steel, cast iron, and hardened alloys. The jobber-length format delivers a versatile flute-to-shank ratio that fits most standard drill chucks and works across a wide range of drilling applications in trade and industrial settings. This bit is appropriate for machinists, pipefitters, HVAC techs, and electricians who regularly drill through tough base metals.\u003c\/p\u003e\u003cp\u003eThis cobalt jobber drill is suited for both shop and field use where a reliable, heat-resistant drill bit is required. Typical applications include metal fabrication, equipment repair, pipe work, and panel drilling. The USA manufacturing origin indicates domestic production standards. It fits standard drill chucks compatible with the size 31 wire gauge drill diameter and is well-suited for production drilling or one-off service calls where bit longevity in hard materials matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for improved heat resistance and hardness over standard HSS bits\u003c\/li\u003e\n\u003cli\u003eSize 31 wire gauge diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eJobber-length flute for versatile reach and chuck compatibility\u003c\/li\u003e\n\u003cli\u003eUSA manufactured\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1, suitable for single-unit purchase\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard wire gauge size 31 jobber-length drill bit compatible with conventional drill chucks accepting the corresponding shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, pipefitters, electricians, and general trade professionals using standard corded or cordless drill equipment or drill presses. Secure the bit firmly in the chuck before operation and ensure the workpiece is properly clamped. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace if chipping or dulling is evident.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: 31 (wire gauge)\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: 0.12 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: C304-131-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233231175986,"sku":"C304-131-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620912.png?v=1780094855","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c304-131-d-cobalt-jobber-drill-size-31","provider":"Voomi Supply","version":"1.0","type":"link"}
