Built from high-speed steel with an oxide finish, it measures 7\/32 inch (0.2188 inch decimal) in diameter and delivers a 135-degree split point for self-centering entry without a center punch. The 6-inch overall length and 2.5-inch spiral flute make it well suited for accessing recessed or obstructed bore locations common in aviation, HVAC fabrication, and sheet metal work. Right-hand cutting direction and a web-thinned, tapered web configuration reduce thrust and improve chip evacuation on production runs.\u003c\/p\u003e\n\u003cp\u003eThis bit is a general-purpose tool used across aviation maintenance, HVAC ductwork, plumbing rough-in, and electrical trade work wherever standard-length bits cannot reach the bore location. The extended body clears obstructions such as framing members, flanges, and panel brackets. It is equally at home in a handheld drill or a drill press. The straight cylindrical shank accepts standard three-jaw chucks, making it compatible with common corded and cordless drills used in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry without center punch marking\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for corrosion resistance and heat tolerance\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides extended reach into recessed or obstructed locations\u003c\/li\u003e\n  \u003cli\u003e2-flute right-hand spiral flute design optimized for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit for use in standard three-jaw chucks on corded drills, cordless drills, and drill presses requiring a 7\/32 inch straight shank bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove drill bits only when the drill is powered off and the chuck is fully released. Secure the workpiece firmly before drilling to prevent walking or grab. Wear appropriate eye protection per applicable shop safety standards. For production drilling in hard stock, use a cutting fluid to extend bit life and reduce heat buildup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/32 inch (0.2188 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inch)\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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\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.E03.0556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749259149618,"sku":"C.E03.0556","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3da2252d57d897ed33d70b5767ec4fee.jpg?v=1788903694","url":"https:\/\/voomisupply.com\/products\/hertel-c-e03-0556-aircraft-extension-drill-bit-7-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
