M2 Disc Styli

Disk Type Styli are for accessing the inside of deeper bores where angling a standard ruby stylus or using a  “Star” Stylus is not feasible.   Smaller disk stylus may have fixed stems up to 20mm long  while larger ones may require stylus extensions depending on measurement depth. Some disk styli also have top and bottom highly spherical balls used to probe undercuts and groove thickness within bores.   Most Disk options are available with M2 Threads though we have thread adapters to work with M3, M4 and M5 threaded probes . Disks may be calibrated on standard origin sphere and can be verified though use of a ring gage   Disc styli are available in various diameters and thicknesses and can be made from steel, ceramic, ruby or other materials. Disc styli are not generally recommended for use on machine tools.   Key:     A = Spherical Diameter   T = Thickness    L = Stem Length Sd =  Stem Diameter    Rt = Roller Thickness
