Walter-titex 5062931 Micro Drill Bit Wire 62 Cobalt

Product Description

The WALTER-TITEX 5062931 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards, this wire gauge size 62 bit measures 0.0382 inches (0.97 mm) in diameter with an overall length of 25 mm (approximately 0.984 inches). The 118-degree standard point angle and web-thinned, tapered web configuration improve penetration and reduce thrust force in tough alloys. The spiral flute design evacuates chips efficiently during through-hole, blind-hole, and stack drilling operations. This is a tool for machinists, toolroom techs, and precision fabricators who require tight tolerances and repeatable performance at small diameters.

This micro drill bit is suited for production and prototype drilling in titanium alloys as its primary workpiece material. Secondary applications include glass and graphite. The straight-cylindrical shank with a 1.50 mm shank diameter seats in standard collet chucks and micro-drill holders. Its 5xD flute-to-diameter ratio supports a maximum drilling depth of 5.00 mm (0.200 inches), making it appropriate for shallow blind holes and through-hole work in thin-section components. The bright, uncoated finish is standard for cobalt tooling used across general and specialty machining environments.

Key Features

• Cobalt tool material provides heat resistance and hardness retention in titanium alloys and abrasive materials
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• Spiral flute with regular spiral type for consistent chip evacuation
• Straight-cylindrical shank at 1.50 mm diameter for compatibility with standard micro-drill holders
• Bright/uncoated finish — no coating buildup at small diameters
• Built to DIN 1899 specification for dimensional consistency across the series

Compatibility

Designed for use in standard collet-style micro-drill holders and CNC machining centers accepting a 1.50 mm straight-cylindrical shank. Suitable for blind-hole, through-hole, and stack drilling applications in titanium alloy, glass, and graphite workpieces per the Walter-Titex Series A3143 design intent.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power isolated or in a safe state per facility lockout/tagout procedures. Ensure the collet chuck is clean and correctly sized for the 1.50 mm shank before clamping to avoid runout at this diameter. At sub-millimeter diameters, excessive feed rate or misalignment is the leading cause of bit breakage — verify spindle runout before drilling. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material.
