Built to DIN 1897 standards, this Series 659 bit measures 0.147 inches (wire size 26) in diameter with an overall length of 2.0472 inches and a 130-degree split point. The parabolic flute geometry and web-thinned point reduce thrust and improve chip evacuation in tough materials. Cobalt construction provides the heat resistance needed when cutting hard alloys. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. This bit is rated heavy duty and carries a maximum drilling depth of 0.567 inches.\u003c\/p\u003e\u003cp\u003eThis drill bit is primarily specified for machining titanium alloy and similarly hard workpiece materials where standard HSS tooling fails prematurely. The stub length format provides added rigidity compared to jobber-length bits, making it well suited for CNC machining centers, manual drill presses, and hand drilling fixtures where deflection must be minimized. The 3xD flute-to-diameter ratio and parallel web configuration support consistent chip flow in deep-hole entry cuts. Machinists, tool-and-die professionals, and aerospace maintenance technicians are the typical end users. Coolant-through capability is not available on this model, so surface or flood coolant application is recommended when drilling titanium.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material rated heavy duty for hard and abrasive alloys including titanium\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eParabolic flute design accelerates chip evacuation and lowers heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eStub length format (DIN 1897) adds radial stiffness and reduces deflection in short-reach applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank diameter of 0.1469 inches fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.018 mm supports close-tolerance hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for machining operations involving titanium alloy and other hard ferrous and non-ferrous materials; compatible with any drill chuck or collet holder accepting a 0.1469-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify chuck runout is within acceptable limits before drilling to protect the close-tolerance shank. When drilling titanium or hard alloys, apply flood or surface coolant to manage heat since this bit does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.147 inches (Wire Size 26)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0472 inches (52.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.567 inches (14.41 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1469 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2598 inches (32.00 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: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\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\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9006590037300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51741060268338,"sku":"9006590037300","price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67468fcc8a9c51476f1351fe8bba59ee.jpg?v=1788829152","url":"https:\/\/voomisupply.com\/products\/guhring-9006590037300-screw-machine-drill-bit-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
