M5, spherical cylinder styli, tungsten carbide cylinder, without shaft
Cylindrical styli measure two-dimensionally and are particularly suitable for narrow workpieces, such as thin sheet metal. Even narrow workpiece edges can be measured well with cylindrical styli. Care must be taken to ensure that the styli axis is mechanically aligned very precisely with the feature axis on the workpiece. A special form are the spherical cylindrical styli, which are mostly used for sheet metal measurement and measurement at sheet metal edges. They have a spherical end and can thus additionally determine the flatness of a surface, for example.
Tungsten carbide cylinders are manufactured using a special grinding process, which theoretically enables the generation of any desired diameter. Hard metal is significantly heavier than other stylus materials, therefore the hard metal version is not recommended for large diameters.
