Built from high speed steel with an oxide coating, it carries a wire gauge size of 55, equivalent to 0.0520 inches in decimal. The 118-degree standard drill point provides a well-proven entry geometry suitable for steel, cast iron, and similar ferrous materials. A web-thinned, tapered web construction reduces the thrust required at the tip and improves chip evacuation. At 1.875 inches overall length with a 0.875-inch flute, this bit suits close-quarters drilling where standard jobber reach is appropriate. Two spiral flutes with a regular helix clear chips consistently in light to moderate feeds.\u003c\/p\u003e\u003cp\u003eThis bit is a fit for trade professionals working in fabrication shops, HVAC equipment manufacturing, plumbing fixture assembly, and general maintenance environments where small-diameter precision holes in metal are routine. The straight-cylindrical shank seats securely in standard 3-jaw drill chucks on corded drills, drill presses, and CNC drill heads. Right-hand cutting direction is the shop standard. Tool performance is rated general purpose, making it appropriate for production drilling in ferrous metals at moderate speeds and feeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 55 (0.0520 inches decimal) for precise small-diameter hole work\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for corrosion resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tapered web for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design for consistent chip evacuation in ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (0.0520 inches diameter) fits standard 3-jaw chuck equipment\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and DIN 338 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard 3-jaw drill chucks on hand drills, drill presses, and CNC drilling equipment accepting straight-cylindrical shanks at 0.0520 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist, maintenance technician, or trained tradesperson should secure the shank fully in a properly sized chuck before operation. Verify spindle speed is appropriate for the workpiece material and bit diameter before drilling. Disconnect power to any machine tool before changing bits. Do not exceed the rated cutting speed for high speed steel in hard materials, as overheating will damage the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0520 inches\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 Diameter\u003c\/strong\u003e: 0.0520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 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: Regular\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 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: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2001G\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\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\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: C71155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709195223346,"sku":"C71155","price":42.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8cc2c5f5d61efd607eeb7e10e2b6455_0d5519a0-20bc-4b13-a771-455a86986ded.jpg?v=1788452668","url":"https:\/\/voomisupply.com\/products\/cleveland-c71155-jobber-drill-bit-wire-size-55-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
