Built from cobalt high-speed steel with a bright, uncoated finish, this bit measures 1\/8 inch (0.1250 inches) in diameter with an overall length of 8.0 inches and a flute length of 5.5 inches. The 135-degree split-point tip reduces walking on entry and requires no center punch in most applications. With two flutes and a general-purpose grade rating, it suits a wide range of production and maintenance drilling tasks performed by machinists, pipefitters, and tool-room technicians.\u003c\/p\u003e\u003cp\u003eThis extra length drill bit is suited for applications requiring extended reach into deep holes, stacked materials, or confined spaces where standard jobber-length bits fall short. The cobalt construction makes it appropriate for drilling stainless steel, hardened alloys, cast iron, and other difficult-to-machine materials. It is a single-piece, individually packaged bit intended for use in hand-held drills, drill presses, and milling machines running appropriate feed and speed settings for cobalt tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree split-point tip reduces thrust force and self-centers on entry\u003c\/li\u003e\n\u003cli\u003e8.0-inch overall length provides extended reach for deep-hole and stacked-material drilling\u003c\/li\u003e\n\u003cli\u003e5.5-inch flute length aids chip evacuation over the extended cutting depth\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with cutting fluids and standard coolant applications\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry balances chip clearance and rigidity for general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose extra length drill bit compatible with standard 1\/8-inch drill chucks on hand-held drills, drill presses, and milling machines requiring cobalt tooling for hard-material applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or trained trade professional familiar with proper speeds and feeds for cobalt drill bits. Secure the workpiece fully before drilling and confirm chuck grip is tight to prevent bit slippage. Use an appropriate cutting fluid or coolant to extend bit life, especially when drilling stainless steel or hardened alloys. Inspect the bit for chipping or wear before each use and replace if the cutting edges show damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.5 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-Point\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: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.02 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.E13.0318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754599842098,"sku":"C.E13.0318","price":37.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bc20c4034c0365d45d0b7b776f79900.jpg?v=1788947001","url":"https:\/\/voomisupply.com\/products\/hertel-c-e13-0318-extra-length-cobalt-drill-bit-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
