Built to DIN 1897 standards, this Series 5524 bit features a 0.201-inch (wire size 7) diameter with a 118-degree four-facet split point for accurate starts and reduced thrust. The M35 cobalt steel construction provides heat resistance and edge retention when cutting through abrasive or work-hardening materials. A web-thinned, tapered web design reduces cutting forces and improves chip evacuation. Licensed machinists, tool-and-die professionals, and industrial maintenance technicians are the primary installers and users of this bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling in light metals, aluminum, and similar materials where a shorter flute length provides added rigidity and reduces deflection. The stub-length body limits overhang when drilling in confined spaces or on short-stroke drill presses and CNC machining centers. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. Maximum drilling depth is 0.722 inches (18.34 mm), making it appropriate for through-hole and blind-hole work within that range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt steel construction for heat and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003e118-degree four-facet split point with web thinning for self-centering starts and reduced thrust\u003c\/li\u003e\n\u003cli\u003eStub-length body (overall length 62 mm) adds rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for aluminum and non-ferrous primary workpiece materials\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 standard; 3xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose stub drill for use in standard drill chucks and collet holders accepting a straight-cylindrical shank; no specific machine model compatibility was provided in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists and maintenance technicians using drill presses, CNC machining centers, or hand-held power drills with a compatible chuck. Ensure the machine is fully de-energized and the chuck is properly tightened before beginning operations. Use appropriate cutting fluid or coolant for the workpiece material even though this bit does not support through-coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace the bit when diameter tolerance can no longer be maintained.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.201 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.722 inches (18.34 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 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: 5524\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: 0.015 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: 9055240051100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728337600818,"sku":"9055240051100","price":15.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19cc2f916d3c0a16358df5573548f70c.jpg?v=1788690527","url":"https:\/\/voomisupply.com\/products\/guhring-9055240051100-cobalt-stub-drill-bit-0-201-in","provider":"Voomi Supply","version":"1.0","type":"link"}
