The ITP Disc Styli stainless steel Prob Ball, Type M, with M5 thread and a 15 mm ball diameter, is a precision probing accessory designed for measuring large inside diameters and integrated undercuts. Built for metrology setups that demand reliability in tight spaces, this disc-style probe delivers repeatable results across demanding applications.

• Material: Stainless steel construction for durability and corrosion resistance in workshop and lab environments.
• Ball diameter: 15 mm spherical tip that provides stable contact geometry for large internal features.
• Thread: M5 external thread for secure mounting to compatible probe heads and stylus assemblies.
• Type: Type M disc stylus designed to access interior features and undercuts where standard disks struggle; note that normal disks are unsuitable for probing in the Z direction (except discs with radius end rollers).
• Applications: Ideally suited for measuring large inside diameters and integrated undercuts in workpieces such as bushings, housings, and bores.

With this Disc Stylus, you gain extended probing reach and improved data quality in challenging geometries. The robust stainless steel body resists wear, while the 15 mm ball tip ensures repeatable contact and accurate radius measurements. Its M5 mounting thread simplifies integration into common probing setups, helping you streamline inspection routines and reduce setup time.
