Built to DIN 1899 standards, this wire gauge size 80 bit measures 0.0135 inches (0.3429 mm) in diameter with a 118-degree standard point angle and a 25 mm overall length. The M35 cobalt construction provides heat resistance and edge retention needed when drilling titanium alloys, hard steels, and abrasive materials. A spiral flute geometry with web-thinned, tapered web configuration reduces thrust and improves chip evacuation in confined drilling conditions. Licensed machinists and precision fabricators are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is suited for blind hole, stack drilling, and through hole drilling operations where tight tolerances are required. The straight-cylindrical shank seats securely in standard collet chucks and drill press spindles. With a flute length of 2.40 mm and a maximum drilling depth of 1.80 mm (0.100 inches), this bit is optimized for shallow, high-precision micro holes. Secondary workpiece materials include glass and graphite in addition to its primary titanium alloy and steel applications. The bright, uncoated finish allows direct inspection of tool condition during service intervals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt construction for heat resistance and extended tool life in titanium alloys and hard materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and accurate entry\u003c\/li\u003e\n\u003cli\u003eWire gauge size 80 diameter (0.0135 inches) for precision micro-drilling applications\u003c\/li\u003e\n\u003cli\u003eSpiral flute, right-hand cut with 25 mm OAL conforming to DIN 1899 specification\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collet chucks and drill spindles\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, stack drilling, and through hole drilling in a single tooling platform\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard micro drill bit for precision machining setups requiring DIN 1899 Series A3143 wire gauge tooling in cobalt M35 grade.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMicro drill bits of this size are installed and operated by machinists and toolroom technicians using calibrated collet chucks or precision drill press spindles. Ensure the machine spindle is fully stopped and de-energized before changing tooling. Verify chuck runout before use, as concentricity is critical at sub-millimeter diameters. Do not exceed the rated maximum drilling depth of 1.80 mm per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0135 inches\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: 2.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.80 mm (0.100 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5062868\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51747543810354,"sku":"5062868","price":169.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_cc3972dc-25f1-4cdc-a73a-14c5d0f50833.jpg?v=1788882251","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062868-cobalt-micro-drill-bit-wire-80","provider":"Voomi Supply","version":"1.0","type":"link"}
