Built to DIN 1899 standards, it features a 0.39 mm diameter, a 118-degree standard point angle, and a web-thinned tapered web configuration that reduces thrust and improves hole entry accuracy at very small diameters. The M35-grade cobalt construction provides elevated heat resistance and edge retention compared to standard high-speed steel. The bright uncoated finish suits applications where coating interaction with the workpiece material is a concern. Licensed machinists, tool-and-die technicians, and precision CNC operators are the typical end users for this class of drill.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for blind hole, through hole, and stack drilling operations. Its primary workpiece designation covers titanium alloys as well as cast iron, non-ferrous metals, and stainless steel. Secondary workpiece materials include glass and graphite. The straight-cylindrical shank with a 1.00 mm shank diameter seats in standard collet chucks or micro-drill holders. The 5xD flute-to-diameter ratio and 3.00 mm flute length are proportioned for controlled chip evacuation in very shallow, tight-tolerance bores. Maximum drilling depth is 2.20 mm. This series is appropriate for production environments where hole position and diameter tolerance are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt construction for enhanced heat resistance and edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tapered web for reduced entry thrust at micro diameters\u003c\/li\u003e\n  \u003cli\u003eDIN 1899 specification compliance ensures dimensional and geometric consistency\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry promotes consistent chip evacuation in blind and through hole operations\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with titanium alloys, glass, and graphite workpieces\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1.00 mm shank for secure seating in collet-style micro-drill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in precision machining of titanium alloys, cast iron, non-ferrous metals, stainless steel, glass, and graphite.

Secure the shank fully in a collet or micro-drill holder and verify runout before drilling. Ensure the drilling machine is at a complete stop before changing tooling. Do not exceed the rated maximum drilling depth of 2.20 mm per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.39 mm (0.0154 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.20 mm (0.100 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\u003eTool Material\u003c\/strong\u003e: Cobalt M35\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\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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Glass, Graphite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A3143\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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5062873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51748641046834,"sku":"5062873","price":167.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_ce2144f9-f6e8-4042-9d09-cc0ed5dcaea4.jpg?v=1788896074","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062873-micro-drill-bit-0-39-mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
