Built to DIN 1897 standards, this Series 659 bit features a 130-degree split point, a parabolic flute design, and a web-thinned, parallel web configuration that reduces thrust and improves chip evacuation. At 0.1969 inches in diameter with a 2.441-inch overall length and a 1.024-inch flute length, it is sized for precision work in tight setups. Diameter tolerance is held to +0.000 to -0.018 mm, making it suitable for close-tolerance applications. The straight-cylindrical shank fits standard drill chucks without modification. This bit is rated as heavy duty and is primarily intended for titanium alloy workpieces.\u003c\/p\u003e\u003cp\u003eThis bit is designed for screw machine and stub-length applications where rigidity and minimal deflection are priorities. Its parabolic flute geometry and 3xD flute-to-diameter ratio make it well suited for short-hole drilling in titanium alloys and other difficult-to-machine materials common in aerospace, toolroom, and precision machining environments. The right-hand cut and coated cobalt construction support higher feed rates and extended tool life compared to standard HSS bits. Maximum drilling depth is 0.728 inches (18.50 mm). Installation is performed by machinists or toolroom technicians using a standard drill press, CNC machining center, or screw machine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction rated heavy duty for titanium alloy and other difficult materials\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry for improved chip evacuation at higher feed rates\u003c\/li\u003e\n\u003cli\u003eDIN 1897 stub length provides increased rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.018 mm for close-tolerance hole requirements\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub drill bit conforming to DIN 1897 for use in standard drill chucks, screw machines, and CNC machining centers accepting a straight-cylindrical shank of 0.1969 inches diameter.

Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before use and verify runout before drilling. Follow machine manufacturer guidelines for feed rate and spindle speed appropriate to cobalt drill bits in the target workpiece material. Inspect the cutting edges and point geometry before each use; do not use a chipped or damaged bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1969 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.441 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.024 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.728 inches (18.50 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\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: 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\u003eDrill Length Type\u003c\/strong\u003e: Stub\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 Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 659\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 9006590050000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734949888306,"sku":"9006590050000","price":27.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/727d0ab89005f8817a91496599a312ec.jpg?v=1788768448","url":"https:\/\/voomisupply.com\/products\/guhring-9006590050000-cobalt-stub-drill-bit-0-1969in","provider":"Voomi Supply","version":"1.0","type":"link"}
