The ITP Disc Styli ruby Prob Ball is a precision spherical-disc probe designed for metrology specialists who measure challenging internal features. With a 6 mm ruby ball and M2 mounting, it excels at capturing large inside diameters and undercuts with reliable accuracy.
- Ball diameter: 6 mm
- Ball material: Ruby (synthetic ruby) for exceptional hardness and wear resistance
- Thread / Mounting: M2 thread for easy integration with compatible probes
- Disc type: Type O spherical disc stylus
- Primary application: Measures large inside diameters and integrated undercuts
- Direction note: Normal disks are unsuitable for probing in the Z direction unless using radius-end rollers
This ruby disc stylus delivers reliable, repeatable measurements in challenging internal geometries. The hard ruby ball resists wear during contact with hard workpiece materials, extending tip life and reducing downtime. The compact M2 mounting and Type O disc geometry enable smooth, stable probing in confined bores and undercuts, improving data quality and process control across manufacturing and inspection workflows.
