Description
The ITP Disc Styli are precision spherical probes designed for measuring large inside diameters and undercuts. This stainless steel, ruby-ball version combines a robust base with a hard-wearing contact surface to deliver reliable, repeatable readings in challenging bore applications.
- Thread: M5 threaded shank for secure, compatible mounting on standard probes and holders.
- Ball Diameter: 35 mm ball diameter provides a contact surface suited to larger bores and complex undercuts.
- Ball Material: Ruby contact ball offers exceptional hardness and wear resistance for repeated measurements on hard-workpiece materials.
- Base Material: Stainless steel base delivers rigidity and corrosion resistance in everyday workshop use.
- Disc Type: Type M spherical disc design optimized for measuring curved or recessed features with minimal deflection.
- Usage Note: Normal disks are unsuitable for probing in the Z direction (except discs with radius end rollers), so plan Z-axis measurements accordingly.
This disc stylus expands your metrology toolkit by enabling precise capture of inner bore geometries and undercut profiles without removing the part from the fixture. The ruby ball maintains consistent contact over many cycles, while the stainless steel base withstands routine handling in busy inspection environments. With its compact M5 thread, it integrates smoothly into existing setups, delivering dependable results for quality control, inspection, and tooling verification. For best results, align the stylus with the bore geometry and apply controlled contact force to preserve ball integrity over time.
