Ground from high-speed steel (HSS) with an oxide finish, this bit features a 118-degree split point and two flutes for efficient chip evacuation. At 24 inches overall length with an 18-inch flute length, it handles deep-reach drilling in metal, wood, and general-purpose materials. The 9\/16-inch diameter (0.5625 inches decimal) suits a wide range of structural and fabrication tasks. Machinists, pipefitters, ironworkers, and maintenance mechanics typically reach for this bit when standard-length tooling falls short on deep structural members or long-reach setups.\u003c\/p\u003e\n\u003cp\u003eThis bit fits general-purpose drilling applications across industrial, commercial, and trade environments. The extended reach makes it well-suited for drilling through thick steel plate, deep timber, conduit work, or structural members where a drill press or right-angle drive requires additional flute length beyond standard jobber dimensions. The HSS construction handles moderate-speed drilling in ferrous and non-ferrous metals without requiring carbide tooling. It is a practical addition to a field or shop kit wherever deep-hole access is a regular requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-inch diameter (0.5625 inches) for medium-to-large hole sizing\u003c\/li\u003e\n  \u003cli\u003e24-inch overall length with 18-inch flute length for deep-reach drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle for general-purpose entry into metal and wood\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides mild corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003eTwo-flute design promotes chip clearance in deep-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose extra length drill bit suitable for use in standard drill chucks and drill presses that accept a 9\/16-inch shank, across metalworking, fabrication, and trade installation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtra length drill bits are more susceptible to deflection than jobber-length bits  -  use a center punch to establish a pilot point before drilling and run at reduced RPM to minimize walking and heat buildup. Secure the workpiece firmly before beginning. Apply cutting fluid when drilling ferrous metals to extend bit life and maintain point geometry. Inspect the cutting edges before each use; a dull or chipped point on an extended bit increases deflection risk significantly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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.E12.1429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":52106116170034,"sku":"C.E12.1429","price":263.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8153218e339970122a49112d3a16cc32_c425f07d-d0c4-438d-a196-34c8888912e9.jpg?v=1790073159","url":"https:\/\/voomisupply.com\/products\/hertel-c-e12-1429-extra-length-drill-bit-9-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
