Built to DIN 1897 standards, it features a 6.00 mm diameter with a 130-degree split point and oxide finish for heat resistance and extended tool life. The web-thinned, tapered web geometry reduces thrust force on entry and helps center the drill without a pilot hole. At 66.00 mm overall length with a 28.00 mm flute length, this stub-length bit delivers rigidity and reduced deflection in short-reach drilling operations. It is suited for machinists, toolroom technicians, and maintenance mechanics working with ferrous metals and high-temperature alloys.\u003c\/p\u003e\n\u003cp\u003eThis bit is optimized for drilling steel, stainless steel, cast iron, and high-temperature alloys in production and maintenance environments. The stub length format makes it well suited for CNC machining centers, drill presses, and hand-held power tools where reduced overhang improves accuracy and tool stability. The straight cylindrical shank fits standard drill chucks and collet systems sized for 6.00 mm shanks. Right-hand cutting direction is standard for conventional drilling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for heat and wear resistance in hard-metal drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with cone relief for aggressive penetration and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces axial thrust and minimizes drill walking\u003c\/li\u003e\n  \u003cli\u003eOxide coating finish improves lubricity and reduces built-up edge on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 stub length provides maximum rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.000 to -0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or production tooling choice for applications requiring a DIN 1897 stub-length drill bit in 6.00 mm diameter. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys. Compatible with any standard drill chuck or collet accepting a 6.00 mm straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized chuck or collet and verify shank seating and runout before drilling. Power down and de-energize all equipment before changing tooling. Use appropriate cutting fluid or coolant for stainless steel and high-temp alloy applications to manage heat buildup, as this bit does not support through-coolant delivery. Follow shop safety practices and applicable ANSI or OSHA machine guarding standards when operating drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 38.00 mm (1.4961 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt M35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 329\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 9003290060000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727244067122,"sku":"9003290060000","price":18.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/699dc7e6f996068c1bebed3769eb207c.jpg?v=1788675291","url":"https:\/\/voomisupply.com\/products\/guhring-9003290060000-cobalt-stub-drill-bit-6mm","provider":"Voomi Supply","version":"1.0","type":"link"}
