Built to DIN 1899 specifications, this bit measures 0.0118 inches in diameter with an overall length of 0.984 inches. The 118-degree faceted point and spiral flute geometry support accurate entry and chip evacuation in tight tolerances. The web-thinned, tapered web configuration reduces thrust load at entry, which is critical at this diameter. The bright, uncoated cobalt construction provides heat resistance without the added coating thickness that can affect dimensional accuracy in micro-drilling operations. Machinists and tool-and-die professionals working with small-bore applications rely on this series for consistent, repeatable results.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for high-precision drilling in light-duty CNC machining centers, manual drill presses, and precision hand drilling fixtures. Primary workpiece material is aluminum, with secondary capability in titanium alloys, covering a broad range of aerospace, automotive, and general metalworking applications. The 5xD flute-to-diameter ratio and maximum drilling depth of 0.057 inches make it appropriate for shallow micro-hole operations. The straight-cylindrical shank with a 1.00 mm diameter seats securely in standard collet and chuck systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for heat resistance and hardness retention in metal drilling\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning reduces entry thrust at micro diameters\u003c\/li\u003e\n\u003cli\u003eSpiral flute with tapered web for improved chip evacuation in blind and through holes\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains precise dimensional tolerances at 0.0118 inches diameter\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard collet systems\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm for tight, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1899 Series 301 micro drill bit suitable for aluminum (material codes K, M, N, P) and titanium alloy (material code S) workpieces in standard collet and precision chuck systems accepting a 1.00 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis micro drill bit should be installed and removed only with the machine spindle fully stopped and the power source locked out. Use a properly sized collet or precision drill chuck to ensure concentricity and minimize runout, which is critical at diameters below 0.015 inches. Inspect the cutting edge before each use, as cobalt micro bits are brittle and susceptible to chipping if mishandled or dropped. Follow the machine manufacturer and applicable shop safety guidelines when programming feed and speed parameters for micro-diameter tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0118 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.057 inches (1.45 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: 1.90 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\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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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: 9003010003000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737816564018,"sku":"9003010003000","price":179.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad39feb5a96bf97447ad1e2584cd42a1.jpg?v=1788793895","url":"https:\/\/voomisupply.com\/products\/guhring-9003010003000-micro-drill-bit-0-0118-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
