Walter-titex 5062886 Micro Drill Bit 0.52 Mm Cobalt

Product Description

The WALTER-TITEX 5062886 is a cobalt micro drill bit designed for precision drilling in demanding materials. Built to DIN 1899 standards, it features a 0.52 mm diameter with a 1.00 mm straight-cylindrical shank, a 118-degree standard point angle, and a web-thinned, tapered web configuration for improved penetration and centering. The bit carries an M35 cobalt material grade and a bright/uncoated finish. Overall length is 25.00 mm with a flute length of 3.40 mm and a maximum drilling depth of 2.60 mm. Spiral fluting with a regular spiral type and a 5xD flute-to-diameter ratio supports chip evacuation in tight bores. This bit is installed by machinists, aerospace fabricators, and precision metalworking professionals using CNC or manual drill presses.

The 5062886 is rated for blind hole drilling, stack drilling, and through hole drilling. Its primary workpiece material is titanium alloy, with material codes K, N, P, and S. Secondary workpiece materials include glass and graphite, with material codes M and O. The right-hand cutting direction and straight-cylindrical shank make it compatible with standard collet chucks and drill chucks accepting 1.00 mm shank tooling. This bit fits applications requiring tight diameter tolerance control, with a drill bit diameter tolerance of plus 0.000 to minus 0.004 mm.

Key Features

• M35 cobalt construction handles titanium alloy, glass, and graphite workpieces
• 118-degree standard point angle with web-thinned, tapered web for accurate entry
• DIN 1899 specification compliance for consistent micro-drill geometry
• Bright/uncoated finish suitable for use without coolant-through requirements
• 5xD flute-to-diameter ratio aids chip evacuation in blind and through-hole applications
• Diameter tolerance of plus 0.000 to minus 0.004 mm supports precision bore sizing

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 1.00 mm straight-cylindrical shank. Compatible with CNC machining centers, drill presses, and manual spindles used in precision metalworking, aerospace fabrication, and electronics manufacturing where micro-diameter drilling of titanium alloy, glass, or graphite is required.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-drill tooling. Secure the 1.00 mm shank fully in the collet or drill chuck and verify runout before drilling to avoid breakage at this diameter. Ensure the workpiece is rigidly fixtured; any movement at 0.52 mm diameter significantly increases the risk of bit failure. Follow machine manufacturer guidelines for spindle speed and feed rate selection when working with titanium alloy or abrasive secondary materials such as glass and graphite.
