Built for reach-critical applications, the 6-inch overall length gives technicians and machinists access to fastener locations that standard-length bits cannot reach. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on entry. An oxide finish provides basic lubrication and mild corrosion resistance during operation. The spiral flute design runs 2.75 inches in length on a straight cylindrical shank, and right-hand cutting direction is standard for conventional drilling setups.\u003c\/p\u003e\u003cp\u003eThis bit is designed for general-purpose drilling in aircraft maintenance, fabrication, and structural assembly work where extended reach is required. The 0.250-inch diameter and Letter E sizing are common in aerospace and industrial fastener drilling applications. The web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation in deeper holes. Professional machinists, aviation maintenance technicians (AMTs), and metalworking tradespeople are the typical end users for this style of extended-length drill bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter E sizing (0.250 inches decimal) for standard aerospace and industrial fastener holes\u003c\/li\u003e\n\u003cli\u003e6-inch overall length for extended reach in confined or deep-clearance drilling locations\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces walking and center-punch steps\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles general-purpose metalworking demands\u003c\/li\u003e\n\u003cli\u003eOxide finish provides basic surface protection and lubrication during use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use aircraft extension drill bit suitable for standard straight-cylindrical shank drill chucks accepting 0.250-inch diameter shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or aviation maintenance technicians following applicable workplace safety and aviation maintenance manual procedures. Secure the straight cylindrical shank firmly in a compatible drill chuck before operation and confirm chuck key is removed prior to powering the drill. Wear appropriate eye protection and secure the workpiece to prevent movement during drilling. Do not exceed the rated speed range for the bit diameter and material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01000165\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700451737906,"sku":"01000165","price":45.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e8036eb4f462a9aac4655c13bc9af39.jpg?v=1788390501","url":"https:\/\/voomisupply.com\/products\/value-collection-01000165-aircraft-extension-drill-bit-e","provider":"Voomi Supply","version":"1.0","type":"link"}
