Built from high-speed steel with a bright uncoated finish, this bit carries a wire gauge size of 29, corresponding to a decimal diameter of 0.1360 inches. The 135-degree split point with web thinning allows the bit to self-center on contact, reducing walking and the need for a center punch. The 6-inch overall length provides reach into recessed or tight areas that standard-length bits cannot access. Licensed HVAC technicians, aviation maintenance professionals, and industrial machinists are the primary installers for this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose drilling in sheet metal, aluminum, and steel structures where extended reach is required. The 1.75-inch spiral flute length provides adequate chip evacuation during drilling operations in both through-hole and blind-hole scenarios. The straight cylindrical shank fits standard drill chucks without adapters. It conforms to NAS 907 Type B standards, making it appropriate for aerospace maintenance and structural repair work in both production and field service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 29 with 0.1360-inch decimal diameter and tight tolerance of +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of metal substrates\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length gives extended reach for deep or obstructed drilling locations\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with right-hand spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standard for aerospace and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit suitable for use in standard drill chucks accepting a 0.1360-inch straight cylindrical shank, conforming to NAS 907 Type B requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is intended for use by machinists, aviation maintenance technicians, and metalworkers operating hand drills, drill presses, or pneumatic drilling equipment. Secure the workpiece before drilling and ensure the chuck is properly tightened to prevent slippage on the straight cylindrical shank. Use appropriate cutting fluid when drilling ferrous materials to extend bit life and maintain tolerance. Inspect the cutting edges for wear before each use, as a dull split point will increase thrust and reduce hole accuracy.\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: 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1360 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: 1.75 inches\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\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: 0.1360 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3957-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C13151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692530925874,"sku":"C13151","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c4964f4c069c034d19e2d19c561636_5127773c-9cf8-4101-b245-f6fb6d6d70b8.jpg?v=1788298999","url":"https:\/\/voomisupply.com\/products\/cleveland-c13151-aircraft-extension-drill-bit-size-29-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
