The ITP Disc Styli stainless steel Prob Ball (KIM505050M50) is a precision spherical disc probe designed for measuring large inside diameters and integrated undercuts. With an M5 thread and a 50 mm ball diameter, this Type N stylus delivers dependable, repeatable contact in demanding inspection tasks.

• Ball diameter: 50 mm
• Thread: M5
• Material: Stainless steel
• Disc type: Spherical disc, Type N
• Primary use: Ideal for measuring large internal diameters and embedded undercuts
• Direction note: Not suited for probing in the Z direction with normal disks (except discs with radius end rollers)

The disc’s stainless steel construction resists wear and corrosion in workshop environments, ensuring longevity across many measurement cycles. The 50 mm ball provides a generous contact area for stable, accurate readings on large bores, while the M5 mounting thread allows quick, secure attachment to compatible probing setups. Type N geometry aligns with common CMM configurations, helping streamline setup and boost data repeatability for interior features.
