Measuring 5\/16 inch in diameter with a 12-inch overall length and a 9-inch spiral flute, this bit provides extended reach without sacrificing rigidity. The 118-degree standard point angle suits general-purpose drilling in a wide range of materials. An oxide finish reduces friction and helps resist corrosion during service. The web-thinned, tapered web construction reduces thrust and improves chip evacuation in deeper cuts.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for metalworking, fabrication, mechanical, and maintenance trades where access depth is a limiting factor. Common applications include drilling through structural members, deep castings, stacked material, and confined spaces in HVAC, plumbing, and electrical rough-in work. The straight-cylindrical shank seats directly into standard drill chucks without adapters, making it compatible with common corded and cordless drilling equipment found on most job sites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra length design: 12-inch overall length with 9-inch flute for deep-reach drilling\u003c\/li\u003e\n\u003cli\u003e5\/16-inch diameter with 118-degree standard point for general-purpose use\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles moderate heat and abrasion\u003c\/li\u003e\n\u003cli\u003eOxide finish reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust and improves chip clearing\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, 2-flute spiral configuration for efficient material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with any standard drill chuck accepting a straight-cylindrical shank in 5\/16-inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, pipefitters, electricians, and general tradespeople using standard corded or cordless drills and drill presses. Secure the straight-cylindrical shank fully in the chuck before use to prevent slippage. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the bit for wear or damage before each use and replace if the cutting edges are chipped or the flutes are clogged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\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\u003eShank Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-C105420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51714288451890,"sku":"BDNA-C105420","price":31.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53424de18c73916d5f94ea752a940f8d.jpg?v=1788498885","url":"https:\/\/voomisupply.com\/products\/import-bdna-c105420-extra-length-drill-bit-5-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
