Built to DIN 1899 standards, it features a 0.0205-inch diameter with a 118-degree faceted point and a web-thinned, tapered web configuration for reduced thrust and cleaner entry. The spiral flute geometry promotes chip evacuation in shallow-hole drilling operations. The overall length is 0.984 inches with a 1.00 mm straight-cylindrical shank. This bit is suited for use in CNC machining centers, benchtop drill presses, and precision hand-held applications where tight tolerances and small-diameter holes are required.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is rated primarily for aluminum and secondarily for titanium alloys, covering material codes K, M, N, P, and S. The 5xD flute-to-diameter ratio and right-hand spiral cut make it appropriate for short, controlled passes in precision components. Maximum drilling depth is 0.103 inches (2.62 mm), consistent with micro-drill applications. It is well-suited to electronics, aerospace component fabrication, and fine mechanical assemblies where hole diameter consistency and surface finish matter. Machining professionals and tool-and-die technicians are the primary installers of this bit type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1899 specification for standardized micro-drill geometry and dimensional tolerance\u003c\/li\u003e\n\u003cli\u003eCobalt construction for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning for reduced entry thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish, suitable for use with cutting fluids on aluminum and titanium alloy workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal in short-depth holes\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling aluminum (material codes K, M, N, P) as a primary workpiece material and titanium alloy (material code S) as a secondary workpiece material.

Power down or e-stop the machine and confirm zero spindle rotation before changing tooling. Micro drill bits are brittle at this diameter — avoid side loading, misaligned entry angles, and excessive feed rates. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0205 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.984 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.103 inches (2.62 mm)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 301\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 9003010005200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747215409458,"sku":"9003010005200","price":172.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a0102f16340f9d14b03e4ec261bef6f.jpg?v=1788877557","url":"https:\/\/voomisupply.com\/products\/guhring-9003010005200-cobalt-micro-drill-bit-0-0205in","provider":"Voomi Supply","version":"1.0","type":"link"}
