Built to DIN 1899 specifications, it features a 118-degree faceted point angle and a right-hand spiral flute with a 5xD flute-to-diameter ratio. The overall length is 0.984 inches with a straight-cylindrical shank diameter of 1.50 mm. The bright, uncoated cobalt construction provides heat resistance and edge retention when working in tough materials. Web thinning with a tapered web configuration reduces entry force and helps center the drill at the start of the cut. Licensed machinists and tool-and-die professionals typically deploy this bit in CNC machining centers, drill presses, and high-speed spindle setups where tight hole tolerances are required.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is suited for precision work in aluminum and titanium alloy workpieces. With a maximum drilling depth of 0.206 inches (5.23 mm) and a diameter tolerance of +0.000 to -0.004 mm, it is appropriate for microelectronics component manufacturing, aerospace part drilling, medical device fabrication, and other close-tolerance machining applications where hole quality and positional accuracy are critical. The Series 301 designation places it within a standardized product family for consistent tooling procurement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction provides elevated heat resistance compared to standard high-speed steel\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning reduces thrust force and improves centering\u003c\/li\u003e\n\u003cli\u003eTapered web configuration supports chip evacuation in shallow, small-diameter holes\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm supports tight hole-quality requirements\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows direct visual inspection of cutting edge condition\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1899 specification for standardized micro drill geometry\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 for use in standard straight-shank drill chucks and collet systems accepting a 1.50 mm shank diameter. Primary workpiece material codes K, M, N, and P cover aluminum and non-ferrous materials; secondary application covers titanium alloys under material code S.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with small-diameter tooling. Ensure the drill chuck or collet is clean and properly torqued before operation to prevent runout, which is especially damaging at micro diameters. Power down and lock out the spindle before changing bits. Avoid applying excessive feed pressure, as cobalt micro drills are brittle at small diameters and will fracture under side load or shock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0413 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: 1.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.206 inches (5.23 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\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 (Material Codes K, M, N, P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Titanium Alloy (Material Code S)\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\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: 9003010010500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737718292786,"sku":"9003010010500","price":177.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/890505384557940b5e2a8d92dd75569d.jpg?v=1788792725","url":"https:\/\/voomisupply.com\/products\/guhring-9003010010500-micro-drill-bit-0-0413-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
