Built from M42 cobalt high-speed steel with a coated finish, it delivers exceptional heat and wear resistance when cutting through tough alloy steels and aluminum. The bit features a 135-degree split point that self-centers on contact and reduces thrust, keeping holes accurate without a center punch. The parabolic flute geometry promotes fast chip evacuation. At 1.875 inches overall length, this stub-length design provides rigidity ideal for production drilling environments where chatter and deflection must be minimized. Licensed HVAC, machining, and mechanical trades rely on this type of bit for short-hole, high-cycle work.\u003c\/p\u003e\u003cp\u003eThe C14271 is sized to wire gauge 31, with a decimal diameter of 0.1200 inches. It fits standard drill presses, CNC machining centers, and hand-held power drills with compatible collet or chuck capacity. Primary workpiece materials include alloy steel and aluminum, making it a go-to choice for job shops, maintenance technicians, and production machinists drilling fastener clearance holes, pilot holes, and tapping pre-drill operations in ferrous and non-ferrous stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for extended tool life in abrasive and hard alloy materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and self-centers without a pilot punch\u003c\/li\u003e\n\u003cli\u003eParabolic flute design accelerates chip removal and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration for improved cutting efficiency\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides maximum rigidity in short-hole applications\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M standard with ANSI specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for screw machine length drill bit applications requiring a wire gauge 31 diameter in cobalt grade, conforming to ASME B94.11M and ANSI specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and used by machinists, tool and die workers, and mechanical maintenance technicians. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before operation. Ensure the workpiece is properly clamped and the spindle speed is set appropriately for the workpiece material and bit diameter before beginning the cut. Inspect the cutting edges for wear or damage before each use and replace bits that show chipping or rounding to maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\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: C14271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716230906162,"sku":"C14271","price":18.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98ecd3d395f400d79adcd9460cdedb49.jpg?v=1788523407","url":"https:\/\/voomisupply.com\/products\/cleveland-c14271-screw-machine-drill-bit-wire-31-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
