With a 1\/4-inch diameter, a 12-inch overall length, and a 9-inch spiral flute, this bit provides extended reach without sacrificing chip clearance or cut quality. The 118-degree standard point angle suits a wide range of metals and general-purpose materials. An oxide finish provides basic lubricity and corrosion resistance. The web-thinned, tapered web design reduces thrust and improves centering at entry. Installed by machinists, maintenance technicians, and trade professionals working with deep assemblies or stacked materials.\u003c\/p\u003e\u003cp\u003eThis extra length drill bit is suited for general-purpose drilling in metalworking, fabrication, and maintenance applications where standard-length bits fall short. The straight-cylindrical shank fits conventional drill chucks without adapters, making it compatible with handheld drills, drill presses, and mill setups. Right-hand cutting direction is standard for typical clockwise-rotation equipment. The 2-flute spiral configuration provides efficient chip evacuation in through-hole and blind-hole drilling scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-inch diameter with 12-inch overall length for deep-reach applications\u003c\/li\u003e\n\u003cli\u003e9-inch flute length promotes chip evacuation over extended drilling depth\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose metal and material drilling\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands heat generated during prolonged cuts\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces entry thrust and improves bit centering\u003c\/li\u003e\n\u003cli\u003eOxide finish adds basic lubricity and surface protection\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 accepting straight-cylindrical shanks in handheld, drill press, and milling machine setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the straight-cylindrical shank firmly in the chuck before operation and verify there is no runout before beginning a cut. Use appropriate cutting fluid or coolant for metal drilling to extend bit life, noting that this bit does not support coolant-through delivery. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed, as a dull bit increases thrust and raises the risk of workpiece damage or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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-C105416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51716284154162,"sku":"BDNA-C105416","price":25.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30dd4ce548fbecaeee318d2e1da4218c.jpg?v=1788523936","url":"https:\/\/voomisupply.com\/products\/import-bdna-c105416-extra-length-drill-bit-1-4-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
