The bit measures 3.1 mm (0.1220 inches) in diameter with a 2-9\/16 inch overall length and features a titanium nitride (TiN) coating that extends tool life by reducing heat buildup and surface wear. The 130-degree split point improves center location and reduces walking on entry. A parabolic flute geometry promotes efficient chip evacuation, making it well suited for production drilling and repetitive-cycle work. This bit is sized in the 3.00 to 4.00 mm range and manufactured to DIN 338 standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for cutting cast iron and steel in industrial and trade applications. The straight-cylindrical shank accepts standard drill chucks without requiring a collet adapter, simplifying use on drill presses, CNC machining centers, and handheld power tools. The web-thinned, tapered web design lowers thrust requirements, which is especially useful when drilling tougher steel alloys or when working with lighter-duty spindles. It carries a high-performance grade designation, reflecting the cobalt substrate and TiN finish combination used in demanding metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt substrate with TiN coating for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web thinning for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry supports efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 1.23 inches (31.35 mm) with a 5xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for metalworking applications involving cast iron and steel workpieces, conforming to DIN 338 jobber-length standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists, tool-and-die professionals, and trade mechanics using standard drill chucks or compatible toolholders. Secure the straight shank fully within the chuck jaws before operation to prevent runout. Use appropriate cutting fluid or coolant when drilling steel to manage heat, even though this bit does not support through-coolant. Inspect the cutting edge and TiN coating for wear 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 Diameter\u003c\/strong\u003e: 3.1 mm (0.1220 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.23 inches (31.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: 0.1220 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 29.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.018 to 0.000 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: 658\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9006580031000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727078818098,"sku":"9006580031000","price":37.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a87cd36b5e91b4a0d8110cdf0fd1303.jpg?v=1788672947","url":"https:\/\/voomisupply.com\/products\/guhring-9006580031000-cobalt-jobber-drill-bit-3-1-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
