Built from high-speed steel (HSS) with an oxide finish, it measures 5\/16 inch in diameter with a 6-inch overall length, giving technicians the extra reach needed in confined or layered assemblies. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on hard or coated surfaces. With a spiral flute configuration and web-thinned, tapered web design, the bit evacuates chips efficiently and requires less feed force during cutting. Licensed tradespeople in HVAC, electrical, and mechanical installation trades commonly rely on extended-reach bits like this for drilling through structural members, sheet metal, and access panels.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose use across residential and commercial job sites wherever extended reach is required. Typical applications include drilling through wall studs, sheet metal panels, equipment frames, and multi-layer materials where standard bit lengths cannot reach. The straight cylindrical shank fits standard drill chucks without adapters. Right-hand cutting direction is compatible with conventional corded and cordless drills. The flute length of 3-3\/16 inches supports effective chip clearance during extended-reach bores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch diameter with 6-inch overall length for extended-reach drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust force and extends bit life\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design with 3-3\/16 inch flute length for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTwo-flute, right-hand cutting geometry for use with standard drill equipment\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 drill chucks accepting a 5\/16 inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by qualified tradespeople including HVAC technicians, electricians, plumbers, and mechanical contractors. Secure the workpiece before drilling and ensure the drill chuck is tightened fully onto the straight shank before operation. Use appropriate cutting speed for the material being drilled and apply steady, even feed pressure to avoid bit deflection at extended lengths. Always wear eye protection and disconnect or de-energize equipment in the work area before drilling into panels or structural members.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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: 3-3\/16 inches (3.1875 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, Self-Centering\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\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\u003eWeight\u003c\/strong\u003e: 0.6 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.E03.0794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732661600562,"sku":"C.E03.0794","price":23.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37bbb1908687ce8cd66f064f997e8fc1.jpg?v=1788745461","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0794-aircraft-extension-drill-bit-5-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
