It features a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. The black oxide coating provides mild corrosion resistance and helps retain cutting fluid at the tip. At 4.606 inches overall length with a 2.953-inch flute, this bit delivers the reach and chip evacuation typical of jobber-length tooling. The straight cylindrical shank measures 0.3189 inches in diameter, compatible with standard drill chucks. Machinists, maintenance technicians, and fabrication professionals will find this bit suited for everyday hole-making operations.\u003c\/p\u003e\u003cp\u003eThe C71286 is built for general-purpose drilling in production and maintenance environments. The right-hand spiral flute geometry promotes efficient chip removal during through-hole and blind-hole applications in ferrous and non-ferrous materials. Conforming to ASME B94.11M and DIN 338 standards, this bit fits into workflows where dimensional accuracy and consistent tolerances are required. The 4xD flute-to-diameter ratio supports stable drilling across a range of workpiece materials and thicknesses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for strength and wear resistance in general-purpose drilling\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning for reduced entry thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose jobber drill bit compatible with standard drill chucks and drill presses accepting a 0.3189-inch straight shank, conforming to DIN 338 and ASME B94.11M specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a standard drill press, hand drill, or CNC drilling machine. Secure the shank fully in the chuck and verify concentricity before drilling to avoid bit deflection. Always wear appropriate eye protection and secure the workpiece before operation. Follow applicable shop safety standards and machine manufacturer guidelines when setting feed rate and spindle speed for the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.10 mm (0.3189 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.606 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.953 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3189 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6535 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard with Web Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2001G\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: C71286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712207913266,"sku":"C71286","price":16.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8cc2c5f5d61efd607eeb7e10e2b6455_5ea87480-aa86-4415-9499-ed90506fc945.jpg?v=1788485161","url":"https:\/\/voomisupply.com\/products\/cleveland-c71286-jobber-drill-bit-8-10-mm-hss-black-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
