Cobalt construction allows the bit to retain hardness at elevated cutting temperatures, making it a reliable choice for production drilling, fabrication shops, and maintenance applications. The jobber-length flute design provides the balance of reach and rigidity that tradespeople depend on for accurate, repeatable holes in both hand-held and drill-press setups.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for metalworking applications across mechanical, HVAC, plumbing, and electrical trades where drilling into hard or abrasive base materials is routine. It handles ferrous metals, cast iron, and work-hardened stainless without the premature dulling common with standard twist bits. The No. 18 size makes it a go-to for tapping prep and clearance holes in light structural and sheet metal work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction resists heat buildup during high-speed or continuous drilling\u003c\/li\u003e\n\u003cli\u003eJobber-length flute balances reach with bit rigidity for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eNo. 18 wire gauge size suits tapping prep and clearance hole applications\u003c\/li\u003e\n\u003cli\u003eCompatible with standard drill chucks used in hand drills and drill presses\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 allows single-unit procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or supplemental cobalt jobber drill bit for use in standard 3-jaw drill chucks across hand-held and bench-mounted drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLicensed machinists, pipefitters, electricians, and HVAC technicians commonly use jobber drill bits for field and shop drilling tasks. Secure the workpiece firmly before drilling and use appropriate cutting fluid on hard metals to extend bit life. Always wear eye protection when drilling metal. Inspect the bit tip for wear or chipping before each use and replace if the cutting edge is damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: No. 18 (wire gauge)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Type\u003c\/strong\u003e: Cobalt Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: S304-118-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233565901106,"sku":"S304-118-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623630.png?v=1780103370","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-s304-118-i-cobalt-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
