Cobalt construction provides superior heat and wear resistance compared to standard high-speed steel, making this bit well suited for drilling hard and abrasive materials. The jobber-length body delivers the reach and rigidity that professional tradespeople expect for general-purpose through-hole drilling. At 0.12 pounds, the bit is lightweight yet built to withstand the demands of regular job-site use. Electricians, plumbers, HVAC technicians, and general contractors reach for cobalt jobber drills when working through stainless steel, cast iron, harder alloys, and other tough substrates.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is appropriate for use in residential and commercial construction and service applications. It fits standard drill chucks and is sized to the No. 40 wire gauge designation, commonly used when precise small-diameter holes are required for tapping, pilot holes, and conduit or fitting work. The USA manufacture indicates compliance with domestic tooling quality standards that many contractors and service shops specify for their tooling inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 40 wire gauge size for precise small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eCobalt construction resists heat buildup and extends tool life on hard materials\u003c\/li\u003e\n  \u003cli\u003eJobber-length body provides balanced reach and rigidity\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.12 pounds for easy handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition to tooling inventory for use in standard drill chucks accepting jobber-length drill bits sized to the No. 40 wire gauge designation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this bit into a compatible drill chuck and tighten securely before operation. Always wear appropriate eye protection when drilling. Match drill speed (RPM) to the material being drilled — harder materials generally require lower speeds and consistent cutting fluid or lubrication to preserve bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: No. 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Cobalt Jobber Drill Bit\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\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: C304-140-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233931329842,"sku":"C304-140-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620911.png?v=1780112459","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c304-140-d-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
