Built to DIN 1897 standards, it measures 10.00 mm (0.3937 inches) in diameter with an overall length of 89.00 mm (3.504 inches) and a flute length of 43.00 mm (1.693 inches). The bit features a 118-degree four-facet split point with web thinning for reduced thrust and cleaner entry. Constructed from M35 cobalt high-speed steel, it delivers elevated heat and wear resistance compared to standard HSS tooling. This is a bright\/uncoated bit with a straight-cylindrical shank, suited for production drilling where short, rigid tooling is preferred.\u003c\/p\u003e\u003cp\u003eThis stub-length drill bit is used in CNC machining centers, drill presses, and manual machine tools where rigidity and reduced deflection are critical. Its 3xD flute-to-diameter ratio and tapered web configuration make it well-suited for drilling aluminum and other non-ferrous metals. The short flute length limits overhang and improves hole straightness in high-volume production environments. Licensed machinists and toolroom technicians commonly select stub-length cobalt drills for applications requiring tight positional tolerances and consistent hole quality across repeated cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt steel construction for improved heat resistance and tool life over standard HSS\u003c\/li\u003e\n\u003cli\u003e118-degree four-facet split point with web thinning reduces thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length body for increased rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit in the 9.50 mm to 11.00 mm (0.3500 to 0.4000 inch) size range, fitting standard drill chucks and collet systems that accept a 10.00 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or toolroom personnel following applicable shop safety procedures. Verify that the drill chuck or collet is clean, undamaged, and properly rated for the shank diameter before securing the tool. Power down and lock out the machine before loading or removing the bit. Do not exceed the recommended maximum drilling depth of 28.00 mm (1.102 inches) for this stub-length tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.504 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm (1.693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 28.00 mm (1.102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 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\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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\u003eWeight\u003c\/strong\u003e: 0.095 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: 9055240100000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728202105138,"sku":"9055240100000","price":34.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46ad23bcd4f5be83c5ee5fefe2591e27.jpg?v=1788689450","url":"https:\/\/voomisupply.com\/products\/guhring-9055240100000-cobalt-stub-drill-bit-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
