Ground from high-speed steel with an oxide finish, this bit delivers consistent performance in ferrous and non-ferrous materials across general-purpose machining applications. The 118-degree split or conventional point geometry suits a wide range of workpiece materials, and the 0.2188-inch diameter provides precise hole sizing. With a 10-inch overall length and a 7.5-inch flute length, the bit accommodates deep-hole work where standard drills fall short. Machinists, maintenance technicians, and fabricators reaching into deep cavities or through thick stock will find this format useful.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose shop and field use, including metalworking, light fabrication, maintenance repair, and production drilling. The extra-length format is commonly selected when access is restricted or when drilling through deep sections of plate, structural stock, or assembled components where a jobber-length bit cannot reach. The oxide finish provides a degree of surface hardness and lubricity that extends tool life in typical dry or light-coolant drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2188-inch diameter for precise hole sizing in general-purpose applications\u003c\/li\u003e\n\u003cli\u003e10-inch overall length for deep-reach drilling beyond standard jobber-length capacity\u003c\/li\u003e\n\u003cli\u003e7.5-inch flute length promotes chip evacuation in deep-hole operations\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle suited to a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability under normal shop cutting speeds\u003c\/li\u003e\n\u003cli\u003eOxide finish reduces friction and extends tool life in dry or lightly lubricated use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra length twist drill bit compatible with standard drill chucks and drill press, mill, or hand drill spindles accepting 0.2188-inch round-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or maintenance technician familiar with drill press, milling machine, or hand-drill operation. Ensure the workpiece is properly secured before drilling and confirm the chuck is tightened to the shank before powering the machine. Apply appropriate cutting fluid for the material being drilled to extend tool life and improve hole quality. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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.E09.0556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732718715186,"sku":"C.E09.0556","price":41.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c36770965855998c59e95e1a245f09e7.jpg?v=1788745998","url":"https:\/\/voomisupply.com\/products\/hertel-c-e09-0556-extra-length-drill-bit-0-2188-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
