Built to DIN 1897 standards, it features a 0.1457 inch (3.70 mm) diameter with a matching straight-cylindrical shank and a 118-degree four-facet split point that reduces walking and improves centering on entry. The web-thinned, tapered web construction lowers thrust requirements and extends tool life. With a total overall length of approximately 2.047 inches (52.00 mm) and a spiral flute length of approximately 0.787 inches (20.00 mm), this bit is suited for close-tolerance work in confined setups where a standard-length drill would be impractical.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for right-hand cutting in screw machine, CNC lathe, and benchtop drill press environments. Its primary workpiece material rating is aluminum, though the M35 cobalt construction also handles stainless steel, high-nickel alloys, and other work-hardening materials where HSS bits fall short. The bright, uncoated finish makes it easy to inspect for wear, and the 3xD flute-to-diameter ratio supports chip evacuation in short, interrupted cuts. Machinists, tool-and-die technicians, and maintenance professionals typically select this bit for production drilling of small-diameter through-holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt steel construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003e118-degree four-facet split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers feed force requirements\u003c\/li\u003e\n\u003cli\u003eDIN 1897 stub-length geometry for rigidity in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 3xD ratio for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish simplifies wear inspection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production drill for use in screw machine operations, CNC turning centers, and drill presses where a DIN 1897 stub-length cobalt bit in the 0.1000 to 0.1500 inch (3.50 to 5.00 mm) size range is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians. Secure the straight-cylindrical shank fully in a collet, drill chuck, or quick-change toolholder rated for the spindle speed appropriate to the workpiece material and diameter. Ensure the spindle and workpiece are fully at rest before changing or inspecting the bit. Follow applicable ANSI B11 machine tool safety standards for guarding and RPM selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1457 inches (3.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.047 inches (52.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.787 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1457 inches (3.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5690 inches (14.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.0007 inches (+0.000 to -0.018 mm)\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9055240037000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748143923506,"sku":"9055240037000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e72341f1067e885a78170716b4f536e9_2e180f0f-5570-4c5c-9d61-c884c3d6170f.jpg?v=1788889617","url":"https:\/\/voomisupply.com\/products\/guhring-9055240037000-cobalt-stub-drill-bit-0-1457-in","provider":"Voomi Supply","version":"1.0","type":"link"}
