Built from high-speed steel (HSS) with an oxide finish, this bit measures 6 inches in overall length and accepts a straight cylindrical shank with a 0.1130 inch diameter. The 135-degree split point is self-centering, eliminating the need for a center punch on most surfaces. The web-thinned, tapered web construction reduces thrust and improves chip evacuation. This bit is intended for use by machinists, aerospace technicians, and maintenance professionals working on aircraft structures, sheet metal assemblies, and other precision fabrication tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for aircraft maintenance, airframe repair, and general precision metalworking applications where extended reach is required. The right-hand spiral flute with a 1.5 inch flute length handles standard ferrous and non-ferrous stock. Its general-purpose tool performance rating makes it appropriate for production and maintenance environments alike. The 135-degree split point geometry improves accuracy on curved or angled surfaces without a pilot hole. Compliance with NAS 907 confirms it meets aerospace drill bit dimensional and performance standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 33 wire gauge size, 0.1130 inch decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry — no center punch required\u003c\/li\u003e\n\u003cli\u003e6 inch overall length for extended reach in confined spaces\u003c\/li\u003e\n\u003cli\u003e1.5 inch spiral flute length with web-thinned, tapered web for reduced thrust\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 aerospace drill bit standard\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, 2-flute design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard straight-shank drill chucks accepting a 0.1130 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or aircraft maintenance technicians using a standard keyed or keyless drill chuck. Secure the workpiece before drilling and verify chuck grip on the straight cylindrical shank before applying power. Follow applicable shop safety procedures and relevant aerospace maintenance manual requirements when drilling aircraft structures. Do not exceed the recommended RPM range for the material being drilled to avoid premature tool wear or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 33\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1130 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: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1130 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eStandard\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.E03.0287\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738802946354,"sku":"C.E03.0287","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9c1744f0c495387d69c067d89cd89af.jpg?v=1788804748","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0287-aircraft-extension-drill-bit-33-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
