Manufactured to DIN 338 and built from M2 high speed steel with an oxide finish, this bit is suited for general-purpose drilling in production and maintenance environments. The spiral flute geometry runs in a right-hand cutting direction, and the web-thinned, tapered web design reduces thrust and improves chip evacuation. Overall length is 101.00 mm with a straight-cylindrical shank. Licensed tradespeople and machinists handling ferrous and cast iron workpieces will find this a reliable production tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for general-purpose drilling in cast iron and steel workpieces, making it a practical choice for machine shops, maintenance facilities, and fabrication operations. The 2-flute spiral configuration and 5xD flute-to-diameter ratio support consistent chip clearing in both manual and CNC drilling applications. The straight-cylindrical shank fits standard drill chucks without adapters, and the Series 205 designation places it in a well-established Guhring jobber drill line built to DIN 338 tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter B size — 0.2378 inches decimal diameter with a tolerance of +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction with oxide coating for improved surface lubricity\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute regular spiral geometry for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (6.04 mm) fits standard drill chucks directly\u003c\/li\u003e\n  \u003cli\u003eDIN 338 Series 205 — built to recognized dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style jobber drill for use in standard drill chucks and drilling fixtures accepting a 0.2378-inch straight-cylindrical shank; rated for cast iron and steel workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a drill press, lathe tailstock, or CNC spindle with an appropriate chuck. Secure the shank fully in the chuck and verify runout before drilling. Always use appropriate cutting fluid or lubricant when drilling steel to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit when dimensional tolerance or surface finish degrades.\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: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2378 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\u003eMaterial Grade\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 63.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.04 mm (0.2378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 38.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 53.94 mm (2.124 inches)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9002050060400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734625681714,"sku":"9002050060400","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_ef16a4df-41ca-45e0-9ddf-3ece53676893.jpg?v=1788763964","url":"https:\/\/voomisupply.com\/products\/guhring-9002050060400-jobber-drill-letter-b-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
