Built to Series 501-6 specifications, it carries a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on curved or hard surfaces. The 0.196-inch diameter corresponds to Wire Size 9 and matches the straight-cylindrical shank diameter, keeping the tool concentric through its full 6-inch overall length. The oxide finish provides mild corrosion resistance during storage and use. Licensed HVAC sheet-metal technicians, aircraft maintenance mechanics, and industrial pipefitters commonly reach for this bit when standard-length drills cannot access recessed fastener locations.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for right-hand spiral flute drilling in ferrous metals, aluminum, and structural sheet stock where extended reach is required. The 2.4375-inch flute length, combined with the 4xD flute-to-diameter ratio, supports chip evacuation during through-hole work in moderate-depth applications. The two-flute, web-thinned, tapered-web geometry reduces thrust load, making it practical for hand-held pneumatic drills and drill presses alike. It is categorized as a general-purpose tool under NAS 907 Type B standards, meaning it meets established aerospace dimensional and performance criteria. Sheet metal and structural trades will find it a reliable addition to an extension-drill kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering, eliminating pilot dimpling on most metal surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web construction reduces drilling thrust and extends tool life\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach into confined or recessed areas\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles ferrous metals, aluminum, and structural alloys\u003c\/li\u003e\n  \u003cli\u003eOxide finish offers light corrosion protection for storage and field use\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose aircraft extension drill bit conforming to NAS 907 Type B, suitable for use in standard 3\/8-inch or larger drill chucks accepting a 0.196-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this drill bit is performed by machinists, sheet metal technicians, and aircraft maintenance mechanics using hand-held pneumatic drills or drill presses. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck key is removed prior to powering the tool. Use appropriate cutting fluid for ferrous materials to reduce heat buildup and extend bit life. Follow applicable shop safety standards and wear eye protection whenever drilling metal.\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: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.196 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: 2.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.196 inches\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\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\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\u003eSeries\u003c\/strong\u003e: 501-6\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: 0.04167 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: 6001349\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722166960434,"sku":"6001349","price":16.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/242a725ff91a89d972c5cf595935e053_12a0fc62-48c1-4e6d-ae5c-ae79a482f291.jpg?v=1788586654","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001349-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
