Part of the Series 3899, it features a 140-degree faceted point geometry with web thinning for accurate hole entry and reduced thrust. The TiAlN coating improves heat resistance and extends tool life in demanding production environments. With a 2.3 mm (0.0906 inch) diameter and a straight-cylindrical shank, this bit is suited for CNC machining centers and precision drill presses where tight tolerances are required. Installation and operation are handled by machinists and tooling specialists working to close-tolerance specifications.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is intended for drilling cast iron and steel workpieces in applications where precise hole sizing and surface finish are critical. The h7 diameter tolerance makes it appropriate for press-fit and close-clearance hole applications. The 5xD flute-to-diameter ratio supports chip evacuation in short, controlled drilling cycles. It is typically used in job shop and production machining environments on CNC equipment where small-diameter, high-accuracy holes are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point with web thinning for clean entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eh7 diameter tolerance for close-tolerance hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute for efficient chip evacuation in through and blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Do not exceed the maximum drilling depth of 8.55 mm (0.3370 inch) in a single pass without a pecking cycle to clear chips. Verify runout and tool projection before initiating the drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.3 mm (0.0906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.0 mm (1.496 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 12.0 mm (0.472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 8.55 mm (0.337 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Treatment\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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3899\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: 9038990023000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728073654578,"sku":"9038990023000","price":48.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecad43ad50de3d79280c815f39845dc4.jpg?v=1788687444","url":"https:\/\/voomisupply.com\/products\/guhring-9038990023000-micro-drill-bit-2-3-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
