It features a 0.252-inch (6.40 mm) diameter, a 118-degree faceted point angle, and a web-thinned tip geometry that reduces entry force and improves centering. The two-flute spiral design and regular helix promote efficient chip evacuation in short-depth drilling applications. At 2.756 inches overall length with a 1.22-inch flute length, this bit fits standard straight-cylindrical shank tool holders used across CNC machining centers, drill presses, and manual screw machines.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance environments where compact tool length, rigidity, and consistent hole quality are priorities. Its stub-length profile reduces deflection in close-tolerance work, making it a reliable choice for machinists, toolroom technicians, and maintenance professionals working with aluminum, soft metals, and similar workpiece materials. The DIN 6539 standard designation confirms interchangeability within metric tooling systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction (Grade K40) for wear resistance and long tool life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned 118-degree faceted point reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eStub-length body minimizes deflection in short-depth, high-precision drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral geometry supports efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6539 specification for consistent dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-cylindrical shank tool holders; suited for aluminum and similar primary workpiece materials as a general-purpose stub-length carbide drill per DIN 6539.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists or toolroom technicians with the machine powered down and in a locked-out state. Ensure the shank is fully seated and the collet or chuck is torqued to the tool holder manufacturer's specification before operation. Inspect the cutting edges for chips or wear before each use, as carbide tooling is brittle and susceptible to damage from improper handling. Coolant-through is not supported on this bit; apply external coolant or cutting fluid appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.252 inches (6.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.756 inches (70.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.22 inches (31.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.843 inches (21.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.40 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Grade K40)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.010 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2463\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9024630064000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732364427570,"sku":"9024630064000","price":106.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb3bd143f28962c2d256fb85eb88b908_d60ad3cc-96c3-4faf-ac50-1b981d25af31.jpg?v=1788742105","url":"https:\/\/voomisupply.com\/products\/guhring-9024630064000-stub-drill-bit-0-252in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
