It features a 0.3543-inch diameter, a 130-degree split point, and a parabolic flute design that promotes efficient chip evacuation and reduced cutting resistance. The straight cylindrical shank provides secure chuck engagement. With a web-thinned, parallel web configuration and a heavy-duty cobalt construction, this bit is built for production environments where tool life and dimensional accuracy matter. It is sized to a DIN 1897 standard and carries a diameter tolerance of +0.000 to -0.022 mm.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling titanium alloys and other difficult-to-machine metals where standard HSS tooling loses its edge prematurely. The Series 659 parabolic flute geometry supports deep-hole chip clearing in a compact stub-length format. The 3xD flute-to-diameter ratio and 1.0430-inch maximum drilling depth make it well suited to CNC machining centers, drill presses, and manual machines used in aerospace, precision fabrication, and industrial maintenance shops. Right-hand cut orientation is standard for conventional spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for extended tool life in titanium alloy and hard metal drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web thinning reduces thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast, reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStub length (DIN 1897) format provides added rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty grade with diameter tolerance of +0.000 to -0.022 mm for precision work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or new-installation drill bit for use in standard drill chucks and collet systems accepting a 0.3543-inch straight cylindrical shank, conforming to DIN 1897 stub-length standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and used by machinists, toolroom technicians, and precision fabricators. Before mounting, confirm the chuck or collet is clean and within rated capacity for the shank diameter. Use appropriate cutting fluid or coolant when drilling titanium alloys to manage heat and extend tool life. Do not exceed the recommended maximum drilling depth of 1.0430 inches without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3543 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\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 84.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.0430 inches (26.50 mm)\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: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 659\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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: 9006590090000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748112924978,"sku":"9006590090000","price":55.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a83c060d5b94068946bd8a4bbe896563.jpg?v=1788889208","url":"https:\/\/voomisupply.com\/products\/guhring-9006590090000-cobalt-stub-drill-bit-0-3543-in","provider":"Voomi Supply","version":"1.0","type":"link"}
