Measuring 1.01 mm in diameter with an overall length of 38 mm and a flute length of 10 mm, this drill delivers tight tolerances under an h7 diameter tolerance classification. The TiAlN coating improves heat resistance and tool life at elevated cutting speeds. A 140-degree faceted point and web-thinned geometry reduce entry force and improve chip evacuation. This drill is installed and used by machinists, tool-and-die technicians, and precision fabricators working with tight-tolerance components.\u003c\/p\u003e\n\u003cp\u003eThe 9038990010100 is suited for drilling cast iron and steel in applications requiring a small-diameter, high-precision hole. The 3.00 mm straight-cylindrical shank fits standard collet chucks and precision drill chucks commonly found on CNC machining centers, drill presses, and manual mills. The 5xD flute-to-diameter ratio and 8.49 mm maximum drilling depth make this drill appropriate for shallow, precise bores in production and prototype work. Its regular spiral flute type supports controlled chip flow in these primary workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.01 mm drill diameter with h7 tolerance for precision fitment\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in K40 material grade for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for improved thermal resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point with web-thinning for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, spiral flute with regular spiral type for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3.00 mm straight-cylindrical shank compatible with standard collet and drill chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Always secure the shank fully in a precision collet or drill chuck and verify runout before cutting, as micro carbide drills are sensitive to lateral load. Power down and lock out the machine spindle before changing tooling. Avoid side loading or peck drilling beyond the rated maximum drilling depth of 8.49 mm, as carbide micro drills are brittle and will fracture under bending stress.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.01 mm (0.0398 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 8.49 mm (0.334 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\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\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K40\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 pounds\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: 9038990010100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738854228274,"sku":"9038990010100","price":49.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3b1ff8f610a0e8d8a5a6079767ab2b1_90954dd4-3b94-4629-a13a-7d8061c74ada.jpg?v=1788805594","url":"https:\/\/voomisupply.com\/products\/guhring-9038990010100-micro-drill-bit-1-01mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
