Built to a 12 inch overall length with a 2.625 inch flute length, this bit uses a 135-degree split point for self-centering entry without a center punch, reducing walking on hard or curved surfaces. The oxide finish provides mild corrosion resistance and reduces friction during cutting. It is suited for general-purpose drilling in metal, and it meets NAS 907 Type B standards, making it appropriate for aerospace and precision fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis extension drill bit is used in applications where standard jobber-length bits fall short. Typical scenarios include drilling through structural members, deep flanges, or tight assemblies in aircraft maintenance, HVAC equipment fabrication, and sheet metal work. The 12 inch overall length combined with a straight-cylindrical shank allows it to seat securely in standard drill chucks. Right-hand cutting direction and a two-flute spiral configuration support clean chip evacuation in through-hole and blind-hole applications. Series 500-12 designation places this bit in a consistent product family for shops that standardize on tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15\/64 inch (0.2344 inch) diameter with matching straight-cylindrical shank for true running in standard chucks\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering and eliminates the need for a center punch on most materials\u003c\/li\u003e\n  \u003cli\u003e12 inch overall length reaches deep or obstructed bore locations inaccessible to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles general-purpose metal drilling including mild steel and aluminum\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust force and improves cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eNAS 907 Type B compliant for use in aerospace and precision fabrication environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with any standard drill chuck accepting a 15\/64 inch straight-cylindrical shank.

Secure the shank fully in the chuck and confirm there is no runout before drilling. Due to the extended length, use the lowest practical spindle speed and apply cutting fluid when drilling ferrous metals to prevent heat buildup and premature wear. Do not use this bit for percussion or hammer drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/64 inch (0.2344 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: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inch)\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: 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\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: 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\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 500-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 6001344\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695252046130,"sku":"6001344","price":31.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00c62afe4afb4c768fcc83692ac48d80_58f4338b-fdd8-4fab-830f-fd110917772e.jpg?v=1788333181","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001344-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
