Built from high-speed steel with an oxide finish, it measures 0.25 inches in diameter and 18 inches in overall length, with a 12-inch flute length that clears chips effectively through extended cuts. The 118-degree split-free point provides self-centering entry into ferrous and non-ferrous materials. With two flutes and a general-purpose grade designation, this bit is suited for production drilling in metal fabrication shops, maintenance environments, and trade applications where reach is the primary constraint.\u003c\/p\u003e\u003cp\u003eThis drill bit is used wherever a technician or machinist must bore through thick stock, deep cross-members, structural steel, pipe walls, or framing assemblies that exceed the reach of a standard jobber-length bit. Typical applications include electrical and plumbing rough-in work through deep structural members, HVAC duct and equipment frame drilling, and general metalworking. The 18-inch overall length makes it particularly useful for electrical trades drilling through multiple stud bays or thick equipment pads without relocating the drill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-inch overall length provides extended reach for deep-hole and through-structure drilling\u003c\/li\u003e\n\u003cli\u003e12-inch flute length promotes chip evacuation throughout the full depth of cut\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands the heat generated during sustained drilling in metal\u003c\/li\u003e\n\u003cli\u003eOxide finish reduces friction and provides light corrosion resistance during use and storage\u003c\/li\u003e\n\u003cli\u003e118-degree point angle suits general-purpose drilling in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute design balances chip clearance with cutting edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with any 3\/8-inch or larger keyed or keyless chuck drill, drill press, or magnetic drill accepting a straight-shank bit at 0.25-inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways secure the workpiece before drilling to prevent rotation or movement during the cut. Ensure the drill chuck is fully tightened on the straight shank before operation. When drilling metal, use cutting fluid or oil to extend bit life and reduce heat buildup, particularly at the full 18-inch depth. Disconnect or de-energize any electrical circuits in the work area before drilling through walls or panels, in accordance with applicable NEC requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 12 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: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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.E11.0635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733703983410,"sku":"C.E11.0635","price":99.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6de9d4e6c4bc73a151db3286ed9049c.jpg?v=1788758532","url":"https:\/\/voomisupply.com\/products\/hertel-c-e11-0635-extra-length-drill-bit-1-4-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
