Built from high-speed steel (HSS) with an oxide finish, this drill carries a 135-degree split point that is self-centering and web-thinned for reduced thrust and accurate hole entry without a center punch. At wire size 43 (0.089 inches decimal), with a 1.25-inch spiral flute length and 12-inch overall length, this tool is purpose-built for reaching confined or deep-clearance locations that a standard-length drill cannot access. It is part of the Series 501-12 product family and conforms to NAS 907 Type B standards.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for professionals working in aircraft maintenance, aerospace fabrication, and precision sheet-metal work who need extended reach in tight structural cavities. The straight-cylindrical shank seats securely in standard drill chucks, and the right-hand cutting direction is compatible with conventional drill presses, hand drills, and pneumatic tools. General-purpose HSS construction handles steel, aluminum, and other common airframe and structural materials without specialized coolant requirements under normal shop conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering and web-thinned for reduced walk and lower entry thrust\u003c\/li\u003e\n  \u003cli\u003eWire size 43 decimal diameter of 0.089 inches for precise, close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length provides extended reach into deep cavities and structural members\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with spiral flutes promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standards for aircraft-grade tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-compatible replacement and general-purpose extension drill bit for use in aircraft maintenance, aerospace fabrication, and precision metalworking applications requiring wire-gauge diameter tooling in extended-reach configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed by aviation maintenance technicians (AMTs), machinists, and sheet-metal fabricators working under standard shop safety protocols. Secure the straight-cylindrical shank fully in the drill chuck before operation to prevent runout or slippage. Use appropriate cutting fluid for hard alloys to extend tool life. Inspect the split point for chipping or wear before each use, and replace if the point is damaged to maintain hole accuracy and prevent bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.089 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: 1.25 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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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: 0.089 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 501-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6001396\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702614556978,"sku":"6001396","price":35.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da3496e4617881f200db3c68936287ae_25075de9-dc64-4b1b-bcf2-edbcfedcadea.jpg?v=1788412326","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001396-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
