The bit features a standard 118-degree drill point angle and a fast spiral flute geometry designed for efficient chip evacuation during through-hole and blind-hole drilling operations. With an overall length of 4.125 inches and a flute length of 2.875 inches, this bit handles general-purpose drilling tasks in metal fabrication, maintenance, and light manufacturing environments. It is installed and used by machinists, millwrights, and general maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling aluminum and similar non-ferrous and ferrous materials in general-purpose applications. The straight cylindrical shank fits standard three-jaw drill chucks on handheld drills, drill presses, and CNC machines. The web-thinned, tapered web design reduces thrust force at the cutting tip, making it a practical choice for production drilling where operator fatigue and feed pressure matter. It is sold individually and is appropriate for both shop and field use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter I size (0.272 inches) with a diameter tolerance of -0.0010 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suited for general-purpose drilling in aluminum and similar materials\u003c\/li\u003e\n\u003cli\u003eFast spiral flute promotes efficient chip removal and reduces heat buildup during drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance and required feed force\u003c\/li\u003e\n\u003cli\u003eBright uncoated high speed steel construction compatible with cutting fluids and oils\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber length drill bit conforming to ASME B94.11M and ANSI specification designation, fitting standard three-jaw drill chucks accepting a 0.272-inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified maintenance technician should secure the shank fully in the drill chuck before operation and verify chuck tightening with a chuck key where applicable. Power down the drill or press and disconnect from the power source before changing bits. Apply an appropriate cutting fluid when drilling ferrous materials to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.272 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.272 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\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\u003eSeries\u003c\/strong\u003e: 2012\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C03086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700502266162,"sku":"C03086","price":17.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dafd8f90da92a5d59c8f2393f0881b2.jpg?v=1788391198","url":"https:\/\/voomisupply.com\/products\/cleveland-c03086-jobber-length-drill-bit-letter-i-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
