M5, Tip styli, tungsten carbide tip, tungsten carbide shaft
Tip styli, also known as taper styli, are required for two measuring tasks. The stylus is used for self-centering probing of grooves or very small bores. On the other hand, it is used when precisely specified positions on the workpiece must be approched with point probing. Pointed measuring probes are made of solid carbide as standard.
Tungsten carbide is the most common shaft material, it combines a very good stiffness with an acceptable thermal expansion. Only the weight can have a negative effect when using large styli. The straight shaft is the simplest stylus design and the one with the longest usable length. The full shaft length can be used as measuring length. Tungsten carbide shafts represent a good combination in terms of weight, rigidity and thermal expansion.
