Walter-titex 5062868 Cobalt Micro Drill Bit Wire 80

Product Description

The WALTER-TITEX 5062868 is a cobalt micro drill bit designed for precision drilling in demanding industrial and machining applications. 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.

This 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.

Key Features

• M35 cobalt construction for heat resistance and extended tool life in titanium alloys and hard materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and accurate entry
• Wire gauge size 80 diameter (0.0135 inches) for precision micro-drilling applications
• Spiral flute, right-hand cut with 25 mm OAL conforming to DIN 1899 specification
• Straight-cylindrical shank compatible with standard collet chucks and drill spindles
• Rated for blind hole, stack drilling, and through hole drilling in a single tooling platform

Compatibility

Designed 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.

Installation Notes

Micro 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.
