Cobalt construction gives the bit increased heat resistance and durability compared to standard high-speed steel, making it well suited for drilling into hard or abrasive materials including stainless steel, cast iron, and hardened alloys. Jobber-length geometry provides a balanced combination of reach and rigidity for general-purpose drilling in trade and industrial applications. This bit is installed by HVAC technicians, plumbers, electricians, and metalworkers who regularly drill through ferrous and non-ferrous metals in both shop and field conditions.\u003c\/p\u003e\u003cp\u003eThe C304-120-D fits Number 20 drill size applications across residential and commercial trade work. It is commonly used when drilling pilot holes, conduit knockouts, or sheet metal penetrations where a standard twist bit would wear prematurely. The USA manufacturing origin reflects consistent dimensional tolerances expected for precision metal drilling. This bit is appropriate for use in hand drills, drill presses, and magnetic base drills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for extended heat resistance in hard-metal drilling\u003c\/li\u003e\n\u003cli\u003eJobber-length design balances reach and rigidity for general-purpose use\u003c\/li\u003e\n\u003cli\u003eNumber 20 drill size for consistent, repeatable hole diameters\u003c\/li\u003e\n\u003cli\u003eManufactured in the USA for consistent dimensional tolerances\u003c\/li\u003e\n\u003cli\u003eCompatible with standard drill chucks used in hand drills and drill presses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose Number 20 jobber-length drill bit compatible with standard keyed and keyless drill chucks on hand drills, drill presses, and magnetic base drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by licensed tradespeople and experienced metalworkers. Always secure the workpiece before drilling and use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life. Inspect the bit for wear or damage before each use and replace when cutting edges show signs of dulling. Follow applicable workplace safety standards when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: Number 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Cobalt Jobber-Length Twist Drill\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: 0.42 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: C304-120-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233492828466,"sku":"C304-120-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620975.png?v=1780101298","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-c304-120-d-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
