Built from high-speed steel with an oxide finish, it delivers reliable cutting performance in applications that require greater reach than a jobber-length bit provides. The 118-degree split-point angle suits a wide range of common materials, and the two-flute geometry clears chips efficiently through the 5.5-inch flute length. With an overall length of 8.0 inches, this bit is suited for machinists, toolmakers, and maintenance technicians who need extended reach in deep-hole or hard-to-access drilling operations.\u003c\/p\u003e\u003cp\u003eThis extra length drill bit is used in general machining, fabrication shops, maintenance and repair facilities, and production environments where standard-length bits cannot reach the required depth. It is appropriate for use in drill presses, milling machines, and hand-held power drills with a standard chuck. The oxide finish provides a modest level of lubricity and surface protection during dry or lightly lubricated drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16 inch (0.4375 inches) diameter for precise, consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e8.0-inch overall length provides extended reach beyond standard jobber bits\u003c\/li\u003e\n\u003cli\u003e5.5-inch flute length supports deep-hole chip evacuation\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle suits general-purpose materials including mild steel, aluminum, and plastics\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands moderate heat generated during drilling\u003c\/li\u003e\n\u003cli\u003eOxide finish adds surface protection and reduces friction at the cutting edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with standard 7\/16 inch drill chucks on drill presses, milling machines, and portable power drills used in machining and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tradespeople familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is properly secured before operation. Wear appropriate eye protection and follow shop safety procedures. Do not exceed the recommended RPM range for the material being drilled, and apply cutting fluid when drilling ferrous metals to extend bit life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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: 0.21 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.E08.1111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747758145842,"sku":"C.E08.1111","price":45.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bc331dbd7e09ddff9811289e1db66bf.jpg?v=1788885136","url":"https:\/\/voomisupply.com\/products\/hertel-c-e08-1111-extra-length-drill-bit-7-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
