It is manufactured from high speed steel with a bright uncoated finish and features a standard 118-degree split point with web thinning for improved centering and reduced feed pressure at entry. The two-flute spiral design with a regular helix promotes chip evacuation in short-to-medium depth holes. Overall length is 1-7\/8 inches with a flute length of 7\/8 inch. Shank diameter matches the drill diameter at 0.0520 inch, fitting standard Jacobs-style chucks and collet holders used in drill presses, CNC drilling centers, and hand drills.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production and maintenance drilling in ferrous and non-ferrous metals, plastics, and similar materials where a fractional or letter size drill is not required and a precise wire gauge hole is needed. The 2002G series is a general-purpose line commonly stocked by machinists, maintenance techs, and fabrication shops that work with small-diameter precision holes. Typical applications include pilot holes, clearance holes for small fasteners, and electronic or instrument assembly work where tight diameter tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 55 drill, 0.0520 inch decimal diameter, for precision small-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for positive centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with regular spiral flute promotes consistent chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.0520 inch diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 standards for jobber length drill geometry and tolerances\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 drill presses, hand drills, and CNC drilling equipment accepting straight-cylindrical shanks in the 0.0520 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists, toolroom technicians, or qualified maintenance personnel familiar with small-diameter drill bit handling. Secure the shank fully in the chuck and verify concentricity before starting the spindle. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life. Small-diameter bits are susceptible to breakage from side loading and excessive feed pressure — apply steady, controlled feed and reduce pressure as the drill breaks through the workpiece.\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 Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0520 inch\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\u003eFinish\/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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 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: 0.0520 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2002G\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\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: C72155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51718262325554,"sku":"C72155","price":42.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cd7f2058bef619a349cc268dbac4e24.jpg?v=1788551309","url":"https:\/\/voomisupply.com\/products\/cleveland-c72155-jobber-drill-bit-wire-55-hss-118","provider":"Voomi Supply","version":"1.0","type":"link"}
