Built to DIN 1897 standards, it features a 0.04-inch (wire size #60) diameter, a 130-degree standard point angle, and a web-thinned parallel web configuration that reduces thrust and improves chip evacuation. The parabolic two-flute geometry moves chips out of the hole efficiently, making it well-suited for short, precise holes in tough workpiece materials. This is a heavy-duty grade tool intended for professional machining environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for applications where a short overall length is required to minimize deflection and maximize rigidity. With an overall length of approximately 1.02 inches (26 mm) and a flute length of approximately 0.24 inches (6 mm), it is ideal for tight-clearance setups, CNC machining centers, drill presses, and screw machine operations. The straight-cylindrical shank seats securely in standard chucks and collets. Primary workpiece material compatibility includes titanium alloy, where the cobalt construction provides the heat resistance and edge retention needed for extended tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with coated finish for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e130-degree standard point angle with web-thinned parallel web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic two-flute design promotes efficient chip evacuation in deep and blind holes\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length minimizes deflection and increases rigidity in close-tolerance setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.014 mm for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit in the GUHRING Series 659 for use in drilling titanium alloy and similarly demanding workpiece materials.

Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation, and verify runout is within acceptable tolerance before beginning a cut. Power down and de-energize the machine completely before changing or inspecting tooling. Do not exceed the recommended drilling depth of 0.176 inches for this stub-length geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.04 inches (Wire Size #60)\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\u003eOverall Length\u003c\/strong\u003e: 26.00 mm (approximately 1.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.00 mm (approximately 0.24 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.176 inches (4.47 mm)\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\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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 -0.014 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\u003eGrade\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9006590010200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728183198002,"sku":"9006590010200","price":25.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d627c960da6fbdf927758362c6bdd8c7.jpg?v=1788689109","url":"https:\/\/voomisupply.com\/products\/guhring-9006590010200-cobalt-stub-drill-bit-0-04-in","provider":"Voomi Supply","version":"1.0","type":"link"}
