Built to DIN 1897 standards, it features a 0.0625 inch (1\/16 inch) diameter, a 130-degree split point, and a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup. The web-thinned, parallel-web construction lowers entry resistance in tough workpiece materials. Right-hand cut with a straight-cylindrical shank, this bit is suited for use in CNC machining centers, drill presses, and hand-held power tools where precise, clean holes are required in challenging alloys.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for primary use in titanium alloy workpieces, making it a practical choice for aerospace, medical device, and precision manufacturing applications. The stub-length (Series 659) body provides added rigidity over jobber-length bits, reducing deflection when drilling short, accurate holes. A maximum drilling depth of 0.300 inch (7.62 mm) and a 3xD flute-to-diameter ratio keep the tool stable and efficient in production environments. Licensed machinists, tool-and-die makers, and CNC operators working with titanium or similar hard alloys are the primary users of this drill bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for extended heat and wear resistance in hard alloys\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle reduces thrust and improves centering on hard materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip removal and lowers cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web construction reduces entry force\u003c\/li\u003e\n  \u003cli\u003eStub-length body increases rigidity and minimizes bit deflection\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1897 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification stub-length drill bit per DIN 1897, suitable for use in standard straight-shank drill chucks on CNC machining centers, drill presses, and pneumatic or electric hand drills where a 0.0625 inch straight-cylindrical shank is accepted.

Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Always wear appropriate eye protection and follow applicable OSHA machine-guarding requirements. Do not exceed the rated maximum drilling depth of 0.300 inch per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 34.00 mm (approximately 1.339 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00 mm (approximately 0.394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.300 inches (7.62 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\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\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\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\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 -0.014 mm\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 9006590015900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731078971698,"sku":"9006590015900","price":19.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ed96776a12a5b8cd6a74ff2d2e6f3a1.jpg?v=1788726697","url":"https:\/\/voomisupply.com\/products\/guhring-9006590015900-cobalt-stub-drill-bit-1-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
