Advantages of Tungsten Carbide Small Diameter Probes:


For small-diameter or short probes (length less than 50mm) requiring high rigidity, tungsten carbide is an ideal choice. It is especially suitable for probes with a ball diameter of φ1.0mm or smaller, offering good rigidity and resistance to deformation.

Recommended: φ1mm ruby ​​ball + tungsten carbide probe (M3/M4) for high-precision measurement of minute features.
