Designed for general-purpose drilling, it features a 118-degree standard point angle and a fast spiral flute configuration with web thinning for improved chip evacuation and reduced thrust. The straight-cylindrical shank seats securely in standard drill chucks, making this bit a reliable choice for machine shop work, maintenance, and fabrication. It is installed and used by machinists, maintenance technicians, and metal fabricators working across a range of production and repair applications.\u003c\/p\u003e\n\u003cp\u003eThe C03108 is suited for drilling aluminum and other non-ferrous metals as its primary workpiece material, though its general-purpose grade makes it functional across a broad range of softer metals and plastics. With a 5.75-inch overall length and a 3.188-inch flute length, it provides adequate reach for most standard jobber-length applications. The two-flute spiral design promotes efficient chip clearance during through-hole and blind-hole drilling operations on drill presses, lathes, and hand-held power drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter O size at 0.3160 inches diameter with a tight tolerance of -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling versatility\u003c\/li\u003e\n  \u003cli\u003eFast spiral, two-flute design with tapered web for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tip reduces cutting resistance and entry thrust\u003c\/li\u003e\n  \u003cli\u003eBright uncoated high speed steel construction for easy visual wear inspection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M standards under ANSI specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber-length drill bit suitable for use in standard drill chucks on drill presses, CNC drilling machines, lathes, and hand-held power drills where a Letter O or 0.3160-inch diameter hole is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and maintenance technicians using standard drill chuck tooling. Ensure the drill press or machine spindle is powered down and brought to a full stop before inserting or removing the bit from the chuck. Secure the shank fully in the chuck and confirm concentricity before beginning a cut. Follow applicable shop safety standards and use appropriate cutting fluid or lubrication when drilling ferrous materials to extend tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: O\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3160 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: Fast\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1880 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.7500 inches (146.05 mm)\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: 0.3160 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (33.34 mm)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2012\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M (ANSI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C03108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691567382834,"sku":"C03108","price":20.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1631d2bfc10c0974eb8ea36c467acf41.jpg?v=1788287080","url":"https:\/\/voomisupply.com\/products\/cleveland-c03108-jobber-drill-bit-letter-o-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
