Built to DIN 1899 specification, this bit features a 1.55 mm (0.0610 inch) diameter with a straight-cylindrical shank measuring 2.00 mm in diameter. The 118-degree faceted point with web thinning and a tapered web configuration reduces entry force and improves centering accuracy. The spiral flute geometry promotes chip evacuation from shallow holes. At 30 mm overall length with a 10.60 mm flute length, this bit suits benchtop drill presses, CNC machining centers, and precision hand drilling fixtures used by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for drilling aluminum, non-ferrous metals, and titanium alloys in production and prototype environments. Its bright uncoated cobalt construction handles elevated cutting temperatures better than standard high-speed steel, making it a practical choice for harder non-ferrous workpiece materials. The Series 301 designation places it within a standardized tool family, which simplifies reordering and tooling management on the shop floor. Typical applications include printed circuit board fixturing, precision instrument housings, and small-diameter through-hole work where dimensional accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for improved heat resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration supports chip clearance in shallow holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard collets and chuck styles\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute cut with regular spiral type for consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.000 to -0.004 mm for close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1899 Series 301 micro drill bit with a 2.00 mm straight-cylindrical shank, suitable for use in standard collet chucks and precision drill fixtures that accept this shank size. Primary workpiece materials are aluminum and non-ferrous metals (material codes K, M, N, P); secondary workpiece material is titanium alloy (material code S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with small-diameter drill bit handling. Secure the shank fully in a precision collet or chuck before operation and verify runout is within acceptable limits, as micro-diameter bits are sensitive to lateral deflection. Do not exceed the maximum recommended drilling depth of 8.28 mm (0.326 inch) for this flute length. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling titanium alloys to manage heat buildup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.55 mm (0.0610 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 8.28 mm (0.326 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: Faceted\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 Type\u003c\/strong\u003e: Spiral (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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 301\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: 9003010015500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734645866802,"sku":"9003010015500","price":248.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/241945ee258f4c9f70f58a1fed864bfc.jpg?v=1788764349","url":"https:\/\/voomisupply.com\/products\/guhring-9003010015500-micro-drill-bit-1-55-mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
