Built to DIN 1899 standards, this bit carries a wire gauge size of 65, measuring 0.0350 inches (0.89 mm) in diameter, with a 1.50 mm straight-cylindrical shank and an overall length of 25 mm. The 118-degree standard point angle and spiral flute geometry make it well suited for controlled entry and chip evacuation in tight-tolerance applications. The bright, uncoated cobalt construction provides the heat resistance needed when working through hard or abrasive workpiece materials. Licensed machinists, tool-and-die technicians, and precision fabricators rely on this type of bit for repeatable, burr-minimized results in production environments.\u003c\/p\u003e\n\u003cp\u003eThe 5062923 is rated for blind hole, through hole, and stack drilling operations. Its primary workpiece materials are titanium alloy and similar high-strength alloys, with secondary suitability for glass and graphite. The 6.00 mm flute length and 4.50 mm maximum drilling depth keep this bit focused on shallow, high-precision passes rather than deep-bore applications. With a 5xD flute-to-diameter ratio and a web-thinned, tapered web configuration, it delivers consistent performance in short-run and production-quantity drilling where dimensional accuracy is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 65 (0.0350 inches) with a diameter tolerance of +0.000 to -0.004 mm for tight-fit applications\u003c\/li\u003e\n  \u003cli\u003eCobalt tool material provides elevated heat resistance compared to standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle suitable for a wide range of metallic and composite workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with right-hand cut promotes efficient chip evacuation in blind and through hole drilling\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for consistent dimensional standards across the Series A3143 line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in titanium alloy as the primary workpiece material, with secondary compatibility for glass and graphite.

Always verify spindle speed and feed rate against the workpiece material before drilling to avoid bit breakage at this diameter. Power down or de-energize the machine spindle completely before changing tooling. Coolant-through is not supported on this bit; use appropriate external lubrication or dry-cutting technique as required by the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0350 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25 mm\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: 4.50 mm (0.2000 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\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: 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\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling, Through Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A3143\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5062923\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51747913400626,"sku":"5062923","price":143.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_100e7f4e-842c-48ef-8bba-5de2be18a33c.jpg?v=1788887015","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062923-micro-drill-bit-size-65-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
