Walter-titex 5062844 Micro Drill Bit 0.1 Mm Cobalt

Product Description

The WALTER-TITEX 5062844 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards, it features a 0.1 mm diameter (0.0039 inches) with a 118-degree standard point angle and a right-hand spiral flute for clean chip evacuation. The cobalt M35 grade construction provides heat resistance and edge retention when drilling hard or abrasive materials. At 25 mm overall length with a 1.0 mm straight-cylindrical shank, this bit is sized for use in precision drilling spindles and CNC micro-drilling operations. Licensed trades and machining professionals rely on this tool for micro-hole work where dimensional accuracy is critical.

This micro drill bit is suited for blind hole, stack drilling, and through-hole drilling applications in titanium alloy as the primary workpiece material. Secondary workpiece materials include glass and graphite. The web-thinned, tapered web configuration reduces thrust force at entry, making it appropriate for thin or brittle materials that require controlled feed rates. With a flute-by-diameter ratio of 5xD and a maximum drilling depth of 0.30 mm, it is intended for shallow, high-precision holes in aerospace, electronics, and precision manufacturing environments.

Key Features

• Cobalt M35 grade material for heat and wear resistance in hard workpiece drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Right-hand spiral flute promotes efficient chip evacuation in blind and through holes
• Straight-cylindrical shank at 1.0 mm diameter fits standard micro-drilling collets and chucks
• Diameter tolerance of +0.000 to -0.004 mm ensures repeatable, tight-tolerance hole sizing
• Bright/uncoated finish maintains consistent cutting geometry without coating buildup at small diameters

Compatibility

Designed for use with titanium alloy as the primary workpiece material and glass or graphite as secondary materials. Conforms to DIN 1899 specification for micro drill bits with straight-cylindrical shanks. Suitable for CNC machining centers and precision drill presses equipped with collets or chucks accepting a 1.0 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with micro-drill handling. Ensure the machine spindle and collet are fully de-energized and stopped before inserting or removing the bit. At 0.1 mm diameter, this tool is extremely fragile — use low runout toolholders and verify spindle concentricity before drilling to prevent breakage. Follow DIN 1899 application guidelines and the machine manufacturer feed-and-speed recommendations for the specific workpiece material.
