Cobalt construction gives this bit the heat resistance and hardness needed to cut through tough materials including stainless steel, cast iron, and hardened alloys without losing temper at the cutting edge. Jobber-length geometry provides a balanced combination of reach and rigidity, making it a practical choice for general-purpose drilling in trade and industrial environments. Electricians, plumbers, pipefitters, and HVAC technicians commonly use jobber-length cobalt bits when drilling through structural steel, metal framing, or heavy-gauge sheet metal.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in both handheld and drill-press applications across residential, commercial, and light industrial job sites. The 3\/8-inch diameter is a commonly required size for conduit knockouts, pipe hanger anchors, bolt clearance holes, and similar trade drilling tasks. Its cobalt composition makes it especially effective where high-speed steel bits overheat or dull quickly under sustained cutting loads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-inch diameter cobalt construction for high heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eJobber-length geometry balances reach with bit rigidity\u003c\/li\u003e\n\u003cli\u003eUSA-manufactured for consistent dimensional and metallurgical quality\u003c\/li\u003e\n\u003cli\u003eSuitable for drilling stainless steel, cast iron, hardened alloys, and structural steel\u003c\/li\u003e\n\u003cli\u003eCompatible with standard 3\/8-inch and 1\/2-inch drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard keyed or keyless drill chuck accepting 3\/8-inch round shanks, including handheld drills and drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCobalt drill bits should be run at appropriate cutting speeds for the material being drilled — slower speeds for harder metals help preserve the cutting edge. Always secure the workpiece firmly before drilling and use cutting fluid or oil when drilling ferrous metals to reduce heat buildup and extend bit life. Wear appropriate eye and hand protection per site safety requirements. Inspect the cutting edges before each use and replace bits showing chipping or rounding at the tip.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inches\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\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: C300-024-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233963835698,"sku":"C300-024-D","price":16.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620636.png?v=1780113332","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c300-024-d-cobalt-jobber-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
