Built from M42 cobalt high-speed steel with a gold oxide coating, this bit handles tough materials where standard HSS bits fall short. It carries a 135-degree split point that reduces walking and allows drilling without a center punch on flat stock. At 3 inches overall length with a 0.1440-inch diameter, it is sized for wire gauge number 27 applications. Right-hand spiral fluting clears chips efficiently, and the web-thinned, tapered web design reduces thrust requirements at the cutting edge. Licensed HVAC technicians, machinists, and trade professionals installing equipment use this type of bit for precision clearance and pilot holes.\u003c\/p\u003e\u003cp\u003eThe C70160 is suited for drilling aluminum and similarly rated workpiece materials in light to heavy-duty production settings. Its straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with benchtop drill presses, hand drills, and CNC equipment. The 1-7\/8-inch flute length provides adequate chip clearance for the depths typical of jobber-length applications. This bit meets NAS 907 Type J standards, making it appropriate for aerospace-adjacent and precision trade work where dimensional tolerances matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat and wear resistance in metal drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and lowers required feed pressure\u003c\/li\u003e\n\u003cli\u003eGold oxide coating provides lubricity and surface protection during cutting\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces thrust load at the tip\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular spiral type for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type J specification for precision and aerospace-adjacent applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length drill bit for wire gauge number 27 applications; fits any standard drill chuck accepting a 0.1440-inch straight-cylindrical shank.

Secure the workpiece fully before drilling and confirm chuck is tightened to prevent bit slippage. Use appropriate cutting fluid or lubricant when drilling metal to extend bit life and maintain dimensional accuracy. Do not exceed the rated cutting speed range for cobalt bits in the applicable workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2213\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51692647842098,"sku":"C70160","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68e71fac92ed610a068aecfe4d190284_e6c96ea0-637d-4caa-8526-b48c2fab300d.jpg?v=1788300563","url":"https:\/\/voomisupply.com\/products\/cleveland-c70160-jobber-drill-bit-wire-27-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
