Built to DIN 1897 standards from M35 cobalt high-speed steel, this bit measures 2.60 mm in diameter with a 43 mm overall length and features a 118-degree four facet split point for fast penetration and accurate hole starting without a center punch. The bright uncoated finish is appropriate for general-purpose use. With a maximum drilling depth of 10.10 mm and a web-thinned, tapered web configuration, it delivers clean entry and reduced thrust in short-hole drilling operations. Licensed machinists, tool-and-die technicians, and precision fabricators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for stub-length drilling operations where rigidity and minimal deflection are required. The shorter flute length of 14 mm and straight-cylindrical shank make it compatible with standard drill chucks, CNC machining centers, and drill presses. Per the supplier specs, the primary workpiece material designation is aluminum, though M35 cobalt construction also supports drilling in stainless steel, cast iron, and other ferrous and non-ferrous metals at appropriate feeds and speeds. It is sold individually (package quantity of 1).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt HSS construction for heat resistance and extended tool life in tough materials\u003c\/li\u003e\n  \u003cli\u003e118-degree four facet split point reduces thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance in short-hole applications\u003c\/li\u003e\n  \u003cli\u003eStub length (DIN 1897) design maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids or dry cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897 Series 5524 stub-length drill bit with a 2.60 mm straight-cylindrical shank; fits standard drill chucks and collet systems accepting a 2.60 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists or tooling technicians familiar with drill press, CNC, or hand-drill setups. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully within the chuck or collet to the manufacturer-recommended grip depth to prevent pullout. Always use appropriate cutting fluid or coolant for the workpiece material to preserve tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.60 mm (0.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 43 mm (1.6929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.60 mm (0.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 29 mm (1.1417 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 10.10 mm (0.3980 inches)\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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 HSS, M35 Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eSeries\u003c\/strong\u003e: 5524\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.004 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9055240026000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732039893298,"sku":"9055240026000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/872fa4110f11640a4139d17435ddf013.jpg?v=1788738555","url":"https:\/\/voomisupply.com\/products\/guhring-9055240026000-cobalt-stub-drill-bit-2-60mm","provider":"Voomi Supply","version":"1.0","type":"link"}
