Built with a 135-degree split point, it is self-centering and starts on contact without walking, reducing the need for a center punch. The 27\/64-inch diameter bit has a flute length of 3-15\/16 inches and an overall length of 6 inches, giving technicians the reach needed to access recessed or obstructed work areas. The bright\/uncoated finish and two-flute spiral design support chip evacuation in metals and composite materials. Installed by aircraft maintenance technicians, fabricators, and metalworking trades, this bit handles general-purpose drilling where accuracy and depth matter.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in aerospace and structural fabrication environments where NAS 907 standards apply. The aircraft extension design addresses common installation challenges in airframes, structural panels, and deep-cavity metalwork where standard-length bits cannot reach. The straight-cylindrical shank provides solid grip in standard drill chucks without slippage during extended-reach operations. General-purpose tool performance makes it a practical choice for production and field repair settings alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edge for durability in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 3-15\/16-inch flute length for extended reach\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency and reduces thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with two-flute spiral design for effective chip removal\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to alter critical diameter tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit meeting NAS 907 standards, suitable for use with standard drill chucks accepting a 27\/64-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this bit is performed by aircraft maintenance technicians, machinists, or qualified metalworking tradespeople. Secure the straight-cylindrical shank firmly in the drill chuck before operation and verify chuck runout is within acceptable tolerances to protect bit concentricity. Always wear appropriate eye protection and follow applicable shop safety and worksite procedures. Inspect the carbide tip for chips or damage before each use and replace if the cutting edge is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inches (0.4219 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: 3-15\/16 inches (3.9375 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: 27\/64 inches (0.4219 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Carbide-Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2610\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 261027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720542683442,"sku":"261027","price":255.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37fc2ba7026fefd8fe6b8b6cea5efdab_d817d5c5-b423-4fbe-9aea-b4eedf2c5dfe.jpg?v=1788565852","url":"https:\/\/voomisupply.com\/products\/value-collection-261027-aircraft-extension-drill-bit-27-64","provider":"Voomi Supply","version":"1.0","type":"link"}
