Cobalt construction provides superior heat resistance compared to standard high-speed steel, making it the right choice when cutting speeds or workpiece hardness generate significant friction. Jobber-length geometry offers the balance of reach and rigidity that tradespeople and machinists rely on for general-purpose through-hole drilling. This bit is suited for use in hand drills, drill presses, and CNC setups where a standard jobber drill is specified.\u003c\/p\u003e\n\u003cp\u003eThe S304-109-I fits residential, commercial, and light industrial applications wherever a Size 9 drill is required. Typical use cases include drilling pilot holes, clearance holes, and through-holes in ferrous and non-ferrous metals during HVAC, plumbing, electrical, and mechanical installation work. It is equally at home in a fabrication shop or on a job site.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for elevated heat and wear resistance when drilling hard metals\u003c\/li\u003e\n  \u003cli\u003eJobber-length design balances reach with torsional rigidity\u003c\/li\u003e\n  \u003cli\u003eSize 9 wire gauge diameter for precise clearance and pilot-hole applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard drill chucks on hand drills, drill presses, and CNC equipment\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1, available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Size 9 cobalt jobber drill suitable for use in any standard drill chuck accepting wire gauge shank diameters in this size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDrilling with cobalt bits should be performed at appropriate speeds for the workpiece material — lower RPM for harder metals and larger diameters reduces heat buildup and extends bit life. Use cutting fluid or a suitable lubricant when drilling ferrous metals to prolong edge life. Secure the workpiece firmly before drilling to prevent walking. Wear appropriate eye protection in accordance with applicable job-site safety requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: 9 (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\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: S304-109-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233702969650,"sku":"S304-109-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623578.png?v=1780107137","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-s304-109-i-cobalt-jobber-drill-size-9","provider":"Voomi Supply","version":"1.0","type":"link"}
