Built to DIN 1897 standards, this bit measures 0.0984 inches in diameter with an overall length of 1.693 inches and a flute length of 0.551 inches. The 130-degree split point with web thinning reduces thrust force and improves centering accuracy. With a parabolic flute design and parallel web configuration, it efficiently evacuates chips from the cut zone. The straight-cylindrical shank provides secure chuck grip. This is a heavy-duty grade tool suited for production and maintenance drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for titanium alloy as its primary workpiece material, making it well suited for aerospace, medical, and precision manufacturing environments. The stub-length body provides added rigidity over jobber-length bits, reducing deflection in short-depth applications. Maximum drilling depth is 0.404 inches, consistent with a 3xD flute-to-diameter ratio. A licensed machinist or toolroom technician would be the typical installer. It conforms to DIN 1897 specification and is manufactured to a diameter tolerance of +0.000 to -0.014 mm.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides heat resistance for drilling hard alloys including titanium\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eStub-length body increases rigidity and reduces deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and CNC toolholders\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 specification with heavy-duty grade rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897-compliant stub-length drill bit suitable for use in manual drill presses, CNC machining centers, and production drilling fixtures that accept a straight-cylindrical shank in 0.0984-inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or CNC operator. Secure the shank fully within the chuck or collet before operation and confirm runout is within acceptable limits. When drilling titanium or other work-hardening alloys, use appropriate cutting fluid and maintain consistent feed pressure to prevent work hardening at the entry point. Do not force the bit or exceed the rated maximum drilling depth of 0.404 inches per pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0984 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.693 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.551 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.404 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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 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\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 9006590025000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755110727986,"sku":"9006590025000","price":19.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ee79bf7fe6b092b39271f28b6c40906.jpg?v=1788951242","url":"https:\/\/voomisupply.com\/products\/guhring-9006590025000-cobalt-stub-drill-bit-0-0984-in","provider":"Voomi Supply","version":"1.0","type":"link"}
