The ITP Disc Styli ceramic Prob Ball is a precision probing accessory designed for metrology professionals who need accurate measurements of large inside diameters and undercuts. With a 20 mm ceramic ball and an M2 mounting thread, this Type M disc stylus delivers stable, repeatable contact in challenging geometries.

• Material: Ceramic ball on a disc tip, offering hardness and wear resistance with minimal thermal expansion
• Ball diameter: 20 mm
• Thread: M2 mounting thread
• Type: Type M
• Applications: Optimized for measuring large inside diameters and integrated undercuts
• Z-direction suitability: Normal disks are unsuitable for probing in the Z direction unless discs with radius end rollers are used

Designed to enhance accuracy in bore inspections and internal feature checks, this ceramic disc stylus helps you capture clean, repeatable data even in recessed areas. Ceramic construction resists wear during repeated passes, while the compact M2 thread keeps your probe assembly tidy and quick to set up. Whether you’re validating bore tolerances on engine housings, measuring large sockets, or validating undercut features in precision molds, the ITP Disc Styli ceramic Prob Ball provides a reliable, durable solution that integrates smoothly with compatible probing systems. By delivering stable contact across complex interior geometries, it helps reduce measurement variability and improve data confidence over time.
