It measures 2.9 mm (0.1142 inches) in diameter with an overall length of 2-13\/32 inches and a parabolic flute for efficient chip evacuation. The 130-degree split point reduces walking and improves penetration in hard materials. Built to DIN 338 standards, this bit is suited for production and maintenance environments where tool life and hole quality matter. Licensed machinists, tool-and-die professionals, and industrial maintenance technicians are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in ferrous materials, specifically cast iron and steel, making it a reliable choice for general-purpose metal drilling in both job-shop and production settings. The straight-cylindrical shank accepts standard drill chucks on benchtop drill presses, CNC machining centers, and hand-held power drills. The parabolic flute geometry and web-thinned point support deeper hole entry without excessive thrust force. It is rated for a maximum drilling depth of 1.130 inches (28.65 mm), consistent with standard jobber-length reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction with TiN coating for extended tool life in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle with web thinning reduces entry thrust and minimizes bit walking\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design with 5xD flute-to-diameter ratio improves chip clearing in deep holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (0.1142 inches diameter) fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with tapered web configuration for stable, consistent hole geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for applications requiring a 2.9 mm cobalt jobber drill conforming to DIN 338 in Series 658.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with metal cutting operations. Secure the shank fully in the drill chuck and verify runout before beginning any drilling cycle. Always use appropriate cutting fluid or coolant for the workpiece material when drilling steel or cast iron to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear before each use and replace the bit if chipping or rounding is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.9 mm (0.1142 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-13\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.130 inches (28.65 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\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\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\u003eShank Diameter\u003c\/strong\u003e: 0.1142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28.00 mm\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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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: -0.014 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 658\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 9006580029000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51746222801202,"sku":"9006580029000","price":36.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18b87ae31f6b87cd92e580456479661c_f7b58ec2-dfac-4694-ad6e-ec0fa101e4fb.jpg?v=1788867309","url":"https:\/\/voomisupply.com\/products\/guhring-9006580029000-cobalt-jobber-drill-bit-2-9-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
