It measures 0.0185 inches in diameter with an overall length of 0.984 inches and features a 118-degree faceted point for accurate entry and reduced walking. The spiral flute geometry supports chip evacuation in shallow-depth operations, while the web-thinned, tapered web configuration reduces cutting resistance at the tip. Manufactured to DIN 1899 specification, this bit is suited for machinists and toolroom technicians who require consistent performance at sub-0.020-inch diameters. The bright, uncoated cobalt construction offers heat resistance without an applied coating.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is designed for drilling aluminum as its primary workpiece material, with titanium alloy as a secondary application. The 5xD flute-to-diameter ratio and a maximum drilling depth of 0.091 inches make it appropriate for CNC machining centers, drill presses, and precision manual setups where shallow, tight-tolerance holes are required. Right-hand cut direction is standard. It is commonly used in aerospace component work, electronics manufacturing, and precision instrument fabrication where fine-feature drilling is routine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0185-inch diameter cobalt construction for sub-miniature drilling applications\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning for precise entry and lower thrust force\u003c\/li\u003e\n\u003cli\u003eSpiral flute type with regular spiral for consistent chip removal in short-depth cuts\u003c\/li\u003e\n\u003cli\u003eDIN 1899 specification ensures dimensional conformance for toolroom and production use\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm for tight-tolerance hole requirements\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with cutting fluids used in aluminum and titanium alloy operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification micro drill bit per DIN 1899 Series 301, suitable for use with standard straight-collet and precision chuck toolholding systems that accept a 1.00 mm straight-cylindrical shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this micro drill bit should be performed by a qualified machinist familiar with small-diameter tooling. Secure the straight-cylindrical shank in a precision collet or micro-chuck rated for the shank diameter to prevent runout. At diameters below 0.020 inches, feed rates and spindle speeds must be carefully controlled to avoid bit breakage. Always verify workpiece fixturing is rigid and that the spindle is fully stopped before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0185 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: 0.091 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\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\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\u003eFlute Length\u003c\/strong\u003e: 3.00 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 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\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\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\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: 9003010004700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748804067634,"sku":"9003010004700","price":172.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5dabf4117806b484284d28fa261cbf88.jpg?v=1788898660","url":"https:\/\/voomisupply.com\/products\/guhring-9003010004700-micro-drill-bit-0-0185in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
