Built from high-speed steel with an oxide finish, it delivers solid performance in general-purpose metal drilling tasks. The bit measures 0.4688 inches in diameter with a 118-degree split-style point for consistent centering and clean entry. At 12 inches overall length with a 9-inch flute length, it clears chips effectively in deep-hole applications. Machinists, fabricators, and maintenance technicians install this bit in drill presses, magnetic drills, or hand-held power drills where extended reach is the job requirement.\u003c\/p\u003e\n\u003cp\u003eThis extra length drill bit is suited for drilling through thick stock, structural steel, cross-member assemblies, and other workpieces where standard 6-inch bits fall short. Typical applications include HVAC and mechanical contractors drilling through structural members during equipment installation, electricians boring through deep wood or steel framing for conduit runs, and plumbers drilling through deep sill plates or structural lumber. The 2-flute geometry supports efficient chip evacuation in both ferrous and non-ferrous materials. It ships individually and is sold as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4688 inch diameter for precise sizing in general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for reliable self-centering on flat and curved stock\u003c\/li\u003e\n  \u003cli\u003e9-inch flute length supports deep chip evacuation and reduces clogging\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length provides extended reach beyond standard-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles repeated use across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild corrosion resistance and reduced galling during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with standard drill chucks accepting round-shank bits up to 0.4688 inches in diameter, including drill presses, magnetic base drills, and corded or cordless hand drills with appropriate chuck capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the bit fully in the chuck before operation and verify chuck key is removed prior to starting the drill. Use cutting fluid or a light machine oil when drilling ferrous stock to extend bit life and reduce heat buildup. Extra length bits are more susceptible to deflection — use a center punch to mark the hole location before drilling, and reduce feed pressure to maintain straightness. Inspect the cutting edges before each use and replace the bit if the point shows signs of chipping or dulling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\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: 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: 0.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.E10.1191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734975643954,"sku":"C.E10.1191","price":63.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/289748f5c2c8f0ec9d65054440420068.jpg?v=1788768779","url":"https:\/\/voomisupply.com\/products\/hertel-c-e10-1191-extra-length-drill-bit-0-4688-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
