Built from high-speed steel with an oxide finish, this bit measures 12 inches in overall length with a 9-inch flute length, giving it significantly more reach than conventional jobber-length bits. The 118-degree standard point angle and web-thinned tip reduce thrust during entry and keep the bit on center. It runs right-hand cutting with a regular spiral and two flutes, making it suitable for a wide range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for maintenance, mechanical, electrical, and plumbing trade applications where deep boring or extended reach is required. Common scenarios include drilling through structural members, deep wall sections, and multi-layer assemblies. The straight-cylindrical shank fits standard drill chucks without adapters, making it easy to mount in corded or cordless drills and drill presses. It is a general-purpose grade bit appropriate for production and service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-inch overall length for extended reach in deep-hole applications\u003c\/li\u003e\n\u003cli\u003e9-inch flute length for effective chip evacuation over long drill depths\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRegular right-hand spiral with 2 flutes and tapered web configuration\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\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 drill chucks and drill press spindles that accept straight-cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit is performed by trade technicians including electricians, plumbers, HVAC installers, and mechanical contractors. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation. Use appropriate feed rate and cutting speed for the material being drilled, and apply cutting fluid when boring through ferrous metals to extend bit life. Ensure workpieces are clamped securely before drilling to prevent movement and bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inches (0.4375 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\u003eShank Length\u003c\/strong\u003e: 3 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 0.01 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: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-C105428\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51706811842866,"sku":"BDNA-C105428","price":65.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6024c1b884adaf725db11bb7572a935.jpg?v=1788436747","url":"https:\/\/voomisupply.com\/products\/import-bdna-c105428-extra-length-drill-bit-7-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
