M5, spherical disc, steel disc

Disc styli are used, among other things, to measure rotationally symmetrical workpieces with undercuts or recesses and bores. However, a strong filtering of the surface roughness usually occurs. With the design of the sphercial disk stylus, a higher accuracy is achieved compared to disk styli.

Steel disks are considerably heavier than ceramic disks, they are primarily used for smaller disk diameters and lower accuracy requirements. Due to the lower strength compared to ceramic, steel disks are not recommended for use on abrasive materials

Discs are screwed directly to extensions or special shafts using clamping disks. Normally, fastening material is not included in the delivery package
