Built from high-speed steel with an oxide finish, this bit features a 135-degree split point for self-centering starts that reduce walking on entry. The 12 inch overall length and spiral flute geometry make it well suited for aerospace-style, automotive, and structural drilling tasks. Two right-hand spiral flutes clear chips efficiently during operation. Web thinning with a tapered web configuration reduces thrust requirements and improves cutting performance through thicker material.\u003c\/p\u003e\u003cp\u003eThis aircraft extension drill bit is intended for professional and trade use in situations requiring extended reach into confined or deep work areas. Typical applications include drilling through aircraft panels, automotive body sections, structural steel, aluminum, and similar materials where a standard jobber-length bit falls short. The straight cylindrical shank fits standard drill chucks without adapters, and the general-purpose tool performance rating covers a broad range of ferrous and non-ferrous materials. It is sold individually and is a direct grab-and-go option for field and shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e25\/64 inch (0.3906 inch) diameter with matching straight cylindrical shank for chuck compatibility\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces bit walking on entry\u003c\/li\u003e\n\u003cli\u003e12 inch overall length provides extended reach for deep or confined drilling locations\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n\u003cli\u003eTwo right-hand spiral flutes with web thinning and tapered web for reduced thrust and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003e3.75 inch flute length accommodates meaningful depth of cut within the extended body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard drill chucks accepting a 25\/64 inch straight cylindrical shank, suitable for use with corded or cordless drills and drill presses in shop or field settings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists, aircraft maintenance technicians, or trade professionals familiar with drilling operations. Secure the workpiece firmly before drilling to prevent movement, and ensure the drill chuck is fully tightened on the straight shank before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life and manage heat buildup. Always wear eye protection and follow applicable shop safety procedures during use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 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: 3.75 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: 25\/64 inch (0.3906 inch)\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: 0.2 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: 01010255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690847174962,"sku":"01010255","price":38.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfb0e27ab269d624f07ed01fefa8e76e.jpg?v=1788276210","url":"https:\/\/voomisupply.com\/products\/value-collection-01010255-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
