Built to DIN 1899 specifications, it features a 0.0228-inch diameter with a 118-degree faceted point and a web-thinned, tapered web configuration that reduces entry force and improves centering. The spiral flute geometry promotes chip evacuation in shallow, small-bore holes. At 0.984 inches overall length with a straight-cylindrical shank, this bit is suited for use in CNC machining centers, drill presses, and high-speed spindle fixtures. Cobalt construction provides heat resistance and edge retention beyond standard HSS tooling. Intended for use by machinists and toolroom technicians working in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is rated for primary use in aluminum and non-ferrous materials, with secondary suitability for titanium alloys. The 5xD flute-to-diameter ratio supports drilling to a maximum depth of 0.119 inches (3.03 mm). Bright uncoated finish is appropriate for materials where coated tooling may cause adhesion or galling. The Series 301 designation identifies this as a standard Guhring micro-drill product line conforming to DIN 1899 geometry. Typical applications include precision part manufacturing, electronics component housings, and aerospace detail work requiring consistent small-bore hole placement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0228-inch diameter cobalt construction for heat and wear resistance beyond standard HSS\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning for reduced thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eSpiral flute with 5xD ratio supports chip evacuation at depths up to 0.119 inches\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 1.00 mm diameter for standard collet and chuck compatibility\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suited for aluminum, non-ferrous metals, and titanium alloys\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1899 specification for consistent geometry and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for primary workpiece materials including aluminum and non-ferrous metals (material codes K, M, N, P) and secondary use in titanium alloys (material code S).

Secure the straight-cylindrical shank fully in a precision collet or chuck before operation to prevent runout-related breakage. Due to the small diameter, use appropriate spindle speeds and feed rates for the workpiece material  -  consult published cutting data for cobalt tooling at this diameter. Inspect the cutting edge under magnification before each use; micro drill bits are susceptible to edge chipping that is not visible to the naked eye.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0228 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\u003eFlute Length\u003c\/strong\u003e: 3.90 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.119 inches (3.03 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 By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 301\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1899\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: 9003010005800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51975252377906,"sku":"9003010005800","price":172.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2735cc65889333f23d609f82fe415dbb.jpg?v=1789977853","url":"https:\/\/voomisupply.com\/products\/guhring-9003010005800-micro-drill-bit-0-0228-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
