Manufactured to DIN 1897 standards, it features a 0.1495-inch diameter, a 130-degree standard point angle, and a parabolic flute design with web thinning for improved chip evacuation and reduced thrust. The straight-cylindrical shank seats securely in standard drill chucks. At 2.165 inches overall length with a flute length of 0.866 inches, this stub-length geometry provides enhanced rigidity compared to jobber-length bits, making it well suited for precision hole-making in tough materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in titanium alloy and is appropriate for other difficult-to-machine metals where heat resistance and edge retention are critical. The cobalt construction provides superior hardness retention at elevated cutting temperatures compared to standard high-speed steel. The parabolic flute geometry with a 3xD flute-to-diameter ratio and parallel web configuration supports efficient chip removal in blind and through-hole applications. It is used in machine shop environments, aerospace fabrication, and industrial maintenance settings by machinists and tool-and-die professionals operating drill presses, CNC machining centers, and hand-held power tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for heat resistance and edge retention in hard metals including titanium alloy\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web thinning reduces entry thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes efficient chip evacuation and reduces clogging\u003c\/li\u003e\n  \u003cli\u003eStub length (screw machine length) provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit suitable for use in drill presses, CNC machining centers, and other standard drilling equipment accepting straight-cylindrical shanks; no specific model compatibility data was provided in the product input.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Ensure the machine spindle is fully stopped and locked out before changing or seating the bit in the chuck. Verify proper chuck engagement along the full shank and confirm appropriate spindle speed and feed rate for the workpiece material before cutting. Coolant-through capability is not supported on this bit; use external cutting fluid when machining titanium or other hard alloys to manage heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.642 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\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\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\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 (Screw Machine Length)\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: 9006590038000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739703836978,"sku":"9006590038000","price":21.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bbb84fe2651a3082502a9b63ac5be39.jpg?v=1788818036","url":"https:\/\/voomisupply.com\/products\/guhring-9006590038000-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
