Built from cobalt high-speed steel, this bit maintains cutting edge integrity at elevated temperatures generated by harder workpiece materials. The 135-degree split-point tip reduces walking on contact, eliminating the need for a center punch in most applications. At 12 inches overall length with a 9-inch flute length, it reaches into deep holes and extended clearance situations that standard jobber-length bits cannot access. Two flutes provide chip evacuation throughout the cut. The bright, uncoated finish suits general-purpose drilling across a wide range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for metalworking and fabrication environments where deep-hole drilling is required in steel, stainless, cast iron, and similar hard materials. Typical applications include structural steel fabrication, HVAC sheet metal work involving thick gauge material, mechanical and piping support fabrication, and general industrial maintenance. The extra length makes it particularly useful when drilling through flanges, deep housings, or stacked material where a standard jobber bit lacks the reach. It is sold individually and is appropriate for use in drill presses, magnetic drills, and hand-held power drills with adequate chuck capacity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance when drilling hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip reduces walk and lowers feed pressure at the start of the cut\u003c\/li\u003e\n\u003cli\u003e12-inch overall length with 9-inch flute length for deep-reach drilling applications\u003c\/li\u003e\n\u003cli\u003eTwo-flute design promotes chip clearing in deep holes\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for general-purpose metalworking use\u003c\/li\u003e\n\u003cli\u003e5\/16-inch diameter with no coolant-through requirement for standard shop setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra length cobalt drill bit compatible with any drill press, magnetic drill, or hand-held power drill accepting a 5\/16-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by machinists, fabricators, and trade professionals familiar with metal-drilling operations. Secure the workpiece fully before drilling and use appropriate cutting fluid on hard or thick materials to extend tool life. Ensure the drill chuck is tightened properly and that the bit runs true before applying feed pressure. Follow applicable shop safety practices including eye protection and secure guarding when operating drill equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split-Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.E14.0794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729678106930,"sku":"C.E14.0794","price":76.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35752cc8d3b8f83f9a185339638cd383.jpg?v=1788707665","url":"https:\/\/voomisupply.com\/products\/hertel-c-e14-0794-extra-length-cobalt-drill-bit-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
