It measures 0.0394 inches in diameter with an overall length of 0.984 inches and features a 118-degree faceted point angle. The cobalt construction provides hardness and heat resistance suited for demanding materials. The spiral flute geometry with a web-thinned, tapered web configuration promotes chip evacuation and reduces thrust during entry. This bit is designed for machinists, tool-and-die technicians, and precision fabricators working with tight-tolerance bore requirements in production or prototype environments.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is intended for use on aluminum as its primary workpiece material, with titanium alloy as a secondary application. The straight-cylindrical shank fits standard drill chucks and collet holders commonly used in CNC machining centers, drill presses, and precision hand-held equipment. With a maximum drilling depth of 0.209 inches and a flute-to-diameter ratio of 5xD, it is suited for through-holes and shallow blind holes in thin stock, sheet metal, and precision components where hole location and diameter accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for elevated hardness and heat resistance in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web-thinned tapered web for reduced entry thrust and improved centering\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish with right-hand spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification micro drill bit per DIN 1899 Series 301, suitable for use in CNC machining centers, bench drill presses, and precision drilling fixtures accepting straight-cylindrical shank tooling with a 1.50 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tool technician. Ensure the machine spindle is fully stopped and locked out before loading or removing the bit. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck to prevent runout. At this diameter, excessive feed rate or side loading will cause bit breakage — follow the tooling manufacturer feed-and-speed recommendations for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0394 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: 0.209 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.80 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, Web-Thinned\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: 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\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: 9003010010000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748035330354,"sku":"9003010010000","price":171.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2ca9dda0ea76616f3e5a52bc798d2da.jpg?v=1788888298","url":"https:\/\/voomisupply.com\/products\/guhring-9003010010000-micro-drill-bit-0-0394-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
