It is ground from high-speed steel with an oxide finish and features a 135-degree split point that is self-centering and web-thinned for reduced thrust and faster penetration without a center punch. The 19\/64 inch (0.2969 inch decimal) diameter runs on a straight cylindrical shank of matching diameter, keeping runout minimal in standard drill chucks. With a 6-inch overall length and a 3-1\/16 inch spiral flute, this bit handles applications where a standard-length bit cannot reach. It cuts right-hand with a two-flute, tapered-web configuration suited to general-purpose metalworking and structural work.\u003c\/p\u003e\n\u003cp\u003eAircraft extension drill bits like the C.E03.0754 are used wherever access depth is the primary challenge: drilling through structural steel, aluminum airframes, HVAC equipment panels, electrical enclosures, plumbing fixture flanges, and pool equipment housings. The extended reach is particularly useful when working through multiple material layers or inside assembled equipment where a standard jobber-length bit would bottom out in the chuck before the cutting edge reaches the workpiece. Trade professionals across sheet metal, HVAC fabrication, electrical rough-in, and light structural work keep extension bits on hand for exactly these clearance situations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering and reduces required thrust at drill entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web design lowers cutting resistance and heat buildup\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach in confined or deep-access work areas\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish resists heat and light corrosion during service\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank seats in standard three-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral geometry clears chips efficiently on right-hand rotation\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 19\/64 inch straight cylindrical shank. Suitable for use in handheld drills, drill presses, and right-angle drill attachments across metal, light structural, and fabrication applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, sheet metal workers, HVAC fabricators, electricians, and other trades requiring deep-reach drilling. Secure the straight shank fully in the chuck and verify concentricity before drilling to prevent bit deflection at extended length. Apply cutting fluid when drilling ferrous materials to extend tool life and reduce heat. Disconnect or de-energize any equipment being drilled into before beginning work, in accordance with applicable lockout\/tagout procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inch (0.2969 inch)\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: 3-1\/16 inches (3.0625 inches)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 19\/64 inch (0.2969 inch)\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\u003eWeight\u003c\/strong\u003e: 0.15 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.E03.0754\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744095928626,"sku":"C.E03.0754","price":24.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/531a30faf8d01198987632c44fef06a6.jpg?v=1788854008","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0754-aircraft-extension-drill-bit-19-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
