✲Thread definition: Helical protrusions on a cylindrical surface. This series adopts metric M2-M5, standard M3/M4.
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.
