Built to DIN 1899 standards, this Series 301 bit features a 118-degree faceted point with web thinning on a tapered web configuration, which reduces thrust and improves centering on entry. The straight-cylindrical shank measures 1.50 mm in diameter, and the overall length is 0.984 inches. The bright, uncoated cobalt construction delivers heat resistance and hardness retention when cutting through demanding materials. Right-hand spiral fluting evacuates chips efficiently while maintaining hole quality in tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for precision machining operations in production and maintenance environments where small-diameter hole accuracy is critical. Its primary rated workpiece material is aluminum, with secondary suitability for titanium alloys. The 5xD flute-to-diameter ratio supports controlled drilling depth up to 0.181 inches (4.59 mm). Typical applications include instrument manufacturing, electronics fabrication, aerospace component drilling, and any trade or industrial setting requiring consistent, repeatable micro-bore results.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for elevated heat and wear resistance without a coating\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration for rigidity across the full flute length\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute promotes efficient chip evacuation in blind and through holes\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.000 to -0.004 mm for close-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1899 specification for consistent dimensional conformance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application micro drill bit for use in standard straight-shank drill chucks and collets accepting a 1.50 mm shank diameter, suitable for CNC machining centers, drill presses, and precision hand-held drilling equipment configured for micro-diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of micro drill bits should be performed by qualified machinists or tooling technicians familiar with small-diameter tooling practices. Secure the straight-cylindrical shank fully into a clean, properly sized collet or chuck before operation, and verify runout before committing to a production cycle. Avoid excessive feed pressure, which can snap tooling at this diameter. Always follow applicable machine safety lockout procedures when changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 63\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0370 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: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.181 inches (4.59 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 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\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\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\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\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\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: 9003010009400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727522201906,"sku":"9003010009400","price":248.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23834a90d74bd70bc668533d604ad990.jpg?v=1788678861","url":"https:\/\/voomisupply.com\/products\/guhring-9003010009400-cobalt-micro-drill-bit-wire-63","provider":"Voomi Supply","version":"1.0","type":"link"}
