Built to DIN 1897 standards, it features a 0.0945-inch (2.40 mm) diameter, a 118-degree four-facet split-point, and a web-thinned, tapered-web design that reduces thrust and improves centering without a center punch. The two-flute regular spiral configuration promotes efficient chip evacuation. Overall length is 43.00 mm with a 14.00 mm flute length, and maximum drilling depth reaches 0.409 inches (10.40 mm). The straight-cylindrical shank seats securely in standard drill chucks and collet holders.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling in aluminum and similar non-ferrous materials where stub-length rigidity reduces deflection in short-reach applications. The cobalt construction maintains cutting-edge hardness under elevated heat, making it appropriate for use in CNC machining centers, drill presses, and hand-held pneumatic or electric tools where consistent hole quality across high cycle counts is required. Machinists, tool-and-die technicians, and production floor operators are the typical end users. The 3xD flute-to-diameter ratio supports controlled depth drilling in close-tolerance setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material retains hardness and cutting performance at elevated temperatures\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 stub-length design increases rigidity and minimizes deflection in short-reach drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral geometry promotes efficient chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.014 mm for consistent, close-tolerance hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production-use drill bit conforming to DIN 1897 stub-length specifications, suitable for use in any standard drill chuck or collet holder accepting a 2.40 mm straight-cylindrical shank. Primary workpiece material is aluminum; suitable for other non-ferrous and soft materials consistent with cobalt-grade tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed with the machine fully powered down and locked out per applicable shop safety procedures. Seat the straight-cylindrical shank fully into the chuck or collet and verify runout before beginning a production run. Coolant-through is not supported on this bit; apply external cutting fluid or mist coolant as required by the workpiece material and feed-speed parameters. Inspect the cutting edges and web-thinned point for wear or chipping before each use, as cobalt bits used past serviceability can produce out-of-tolerance holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0945 inches (2.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.409 inches (10.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet Split\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 5520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: 9055200024000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755394040114,"sku":"9055200024000","price":96.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/905a5006a23292a1fffffa23d3b1b98c_25bc05ea-d052-44b7-9413-70e808c78998.jpg?v=1788954507","url":"https:\/\/voomisupply.com\/products\/guhring-9055200024000-cobalt-stub-drill-0-0945-in","provider":"Voomi Supply","version":"1.0","type":"link"}
