The ITP Disc Stylus is a stainless steel spherical probe designed for precise internal diameter measurements and complex bore features. With a compact M5 threaded mount and a 40 mm ball diameter, it delivers stable contact for large inner geometries in metrology setups.

• Material: Stainless steel for durability, corrosion resistance, and long-lasting performance.
• Ball diameter: 40 mm spherical probing surface, ideal for large inside diameters and intricate bore features.
• Thread: M5 mounting thread for quick, secure attachment to standard probe heads.
• Type: Type O configuration to provide consistent probing behavior.
• Applications: Specifically suited for measuring large inside diameters and integrated undercuts in machined parts.
• Z-direction note: Normal disks are unsuitable for probing in the Z direction unless discs with radius end rollers are used.

This disc stylus offers reliable, repeatable contact on internal surfaces where smaller probes may struggle, enabling accurate bore diameter assessments and feature characterization. The robust stainless steel build stands up to routine cleaning and repeated use in shop environments, while the 40 mm ball provides a stable measurement footprint across challenging bore geometries. Its M5 mount ensures compatibility with a wide range of metrology setups, making it a practical upgrade for CMMs and standalone inspection stations. Ideal for inspectors and engineers working with housings, industrial valves, and other components with large internal features and undercuts.
