Built to DIN 1899 specifications, this bit measures 1.59 mm (0.0626 inches) in diameter with a 30 mm overall length and a 10.60 mm flute length. The 118-degree faceted point geometry and web-thinned, tapered web construction reduce entry force and improve centering accuracy. The bright, uncoated cobalt construction offers solid heat resistance without a coating that could alter the cutting edge profile. Licensed machinists, toolmakers, and precision fabricators rely on this bit for tight-tolerance micro-drilling work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision machining environments where small-bore accuracy is critical. Primary workpiece materials include aluminum and non-ferrous metals, with secondary suitability for titanium alloys and other difficult-to-machine materials. The straight-cylindrical shank (2.00 mm diameter) fits standard collet chucks and drill presses used in CNC and manual machining setups. With a maximum drilling depth of 8.22 mm (0.324 inches) and a 5xD flute-to-diameter ratio, it handles through-hole and blind-hole operations in compact workpiece geometries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for increased hardness and heat resistance over standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point angle with web-thinned, tapered web for reduced thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains consistent edge geometry right out of the package\u003c\/li\u003e\n  \u003cli\u003eDIN 1899 Series 301 specification ensures dimensional conformance for repeatable performance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 2.00 mm diameter for compatibility with standard collet and chuck systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation in shallow micro-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or production-use micro drill bit for machining centers, CNC drill presses, and manual drilling fixtures that accept a 2.00 mm straight-cylindrical shank. Rated primarily for aluminum and non-ferrous workpieces, with secondary suitability for titanium alloy as noted in manufacturer data.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with micro-diameter tooling. Secure the shank fully in a precision collet or chuck rated for the 2.00 mm shank diameter before use. Power down and lock out the machine before loading or unloading the bit. Micro-diameter cobalt bits are brittle under lateral loading — avoid side pressure and use consistent feed rates appropriate for the workpiece material to prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.59 mm (0.0626 inches)\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: 8.22 mm (0.324 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\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 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  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 9003010015900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749829017906,"sku":"9003010015900","price":249.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b533791003904aa5238363d579ab736.jpg?v=1788910976","url":"https:\/\/voomisupply.com\/products\/guhring-9003010015900-micro-drill-bit-1-59mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
