Built from high-speed steel with an oxide finish, this bit features a 135-degree split point that is self-centering and reduces the need for a center punch on most materials. The spiral flute geometry promotes efficient chip evacuation during the cut. With a 3\/16-inch diameter and a 6-inch overall length, it is suited to precision work in tight or recessed locations. The web-thinned, tapered web configuration reduces thrust requirements and helps maintain accurate hole placement.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for general-purpose drilling in metal, sheet stock, and structural materials where extended reach is required. Typical applications include aircraft assembly and maintenance, HVAC sheet metal fabrication, electrical panel work, and structural steel installations. The straight cylindrical shank seats securely in standard drill chucks without slippage during operation. Right-hand cutting direction is standard for conventional drill press and handheld drill use. The 2-5\/16-inch flute length provides adequate chip clearance even when drilling at full depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering and eliminates walking on most surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of metals and structural materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides a base level of corrosion resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length delivers extended reach into recessed or deep work areas\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design promotes efficient chip evacuation throughout the cut\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 standard 3\/16-inch drill chucks on handheld drills, drill presses, and right-angle drill attachments used in metal fabrication and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist, sheet metal mechanic, or qualified tradesperson should install and operate this bit in accordance with applicable workplace safety standards. Secure the straight cylindrical shank firmly in the chuck before operation and verify there is no runout before drilling. Always wear appropriate eye protection and secure the workpiece to prevent movement during the cut. Reduce feed pressure as the bit breaks through the far side of the material to avoid grabbing or bit deflection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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: 2-5\/16 inches (2.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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\u003eFinish\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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.E03.0476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749554094386,"sku":"C.E03.0476","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86a9d0f2bd97e8b4118ce8f49ef50a4c.jpg?v=1788907541","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0476-aircraft-extension-drill-bit-3-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
