Built from high-speed steel with a bright, uncoated finish, it carries a wire gauge size of 50, which equals 0.0700 inches in decimal. The 135-degree split point is self-centering, reducing walking on entry and allowing drilling to start without a center punch in most applications. The extended 6-inch overall length makes it well suited for reaching into confined areas where a standard-length bit cannot. A licensed technician, machinist, or skilled tradesperson typically selects this bit when standard reach is insufficient for the job at hand.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in aerospace, aviation maintenance, and general metalworking applications where extended reach and precision are required. The NAS 907 Type B standard rating confirms it meets established aerospace tooling specifications. With a 1-inch spiral flute and right-hand cutting direction, it clears chips efficiently during through-hole and blind-hole drilling in sheet metal and structural members. It performs as a general-purpose tool across a range of base materials where high-speed steel provides adequate hardness and heat resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 50 (0.0700 inches decimal) for precise small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry reduces walking and eliminates the need for a pilot hole in most setups\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach into confined or deep-access areas\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers reliable hardness for general-purpose metalworking\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with web-thinned, tapered web design improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B aerospace tooling standard\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit conforming to NAS 907 Type B specifications, suitable for use with standard straight-shank drill chucks and compatible drilling equipment in aerospace and metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists, aerospace maintenance technicians, and skilled tradespeople using compatible hand drills or drill presses fitted with a straight-shank chuck. Ensure the drill is powered off and the chuck is secure before inserting or removing the bit. Use appropriate cutting fluid or coolant when drilling hard metals to extend tool life and maintain hole quality. Inspect the bit for wear or chipping before each use, as a damaged cutting edge will affect hole diameter accuracy and surface finish.\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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0700 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: 1 inch\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, Self-Centering\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: 0.0700 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, 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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 3957-6\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: 0.1 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C13172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711423185202,"sku":"C13172","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c4964f4c069c034d19e2d19c561636_fbe3fb29-7284-4385-89a6-8452b6bdb057.jpg?v=1788476492","url":"https:\/\/voomisupply.com\/products\/cleveland-c13172-aircraft-extension-drill-bit-size-50-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
