Manufactured to DIN 1897 standards, this stub-length bit features a 0.1719 inch (11\/64 inch) diameter, a 130-degree split point, and a parabolic flute geometry with web thinning for fast chip evacuation and reduced thrust. The straight-cylindrical shank mounts in standard drill chucks and quick-change holders. With a 2-flute parabolic design and a 3xD flute-to-diameter ratio, this bit handles high-performance drilling in difficult materials including titanium alloy. It is a heavy-duty grade tool suited for production environments and machine shop use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for stub-length drilling operations where rigidity and hole accuracy matter in tight workpiece setups. Its primary rated workpiece material is titanium alloy, though cobalt construction also supports drilling in stainless steel, hardened steel, and other high-strength alloys. The web-thinned, parallel-web configuration reduces the force needed to start and advance the cut. With an overall length of approximately 2.28 inches and a flute length of approximately 0.94 inches, it fits short-reach setups common in screw machine, turret lathe, and CNC drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle for aggressive, self-centering entry on hard materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with web thinning promotes efficient chip evacuation and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 stub-length standard for maximum rigidity in short-reach drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.018 mm for controlled hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897 Series 659 stub-length drill bit for use in standard drill chucks, screw machines, turret lathes, and CNC machining centers that accept straight-cylindrical shanks.

Secure the straight shank fully and concentrically in the chuck before operation to avoid runout. Set spindle speed and feed rate according to the workpiece material and machine specifications before starting the cut. Coolant-through is not supported on this bit; apply external cutting fluid at the point of contact when drilling titanium or other heat-sensitive alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1719 inches (11\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (approximately 2.28 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm (approximately 0.94 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.687 inches (17.45 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-to-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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 9006590043700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732518273330,"sku":"9006590043700","price":26.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc5a7131bf3d00975f5941f26292050a.jpg?v=1788743907","url":"https:\/\/voomisupply.com\/products\/guhring-9006590043700-cobalt-stub-drill-bit-0-1719-in","provider":"Voomi Supply","version":"1.0","type":"link"}
