The ITP Disc Styli stainless steel Prob Ball with M5 thread and a 30 mm ball diameter is a precision spherical disc probe designed for metrology tasks involving large inside diameters and integrated undercuts. This Type N disc (KIM504030080) is built for reliable performance in challenging bore measurements.

• Material: Stainless steel for durability and corrosion resistance.
• Ball diameter: 30 mm to access larger internal features and undercuts.
• Thread: M5 threaded shank for secure mounting on compatible probes.
• Disc type: Type N geometry optimized for stable contact on internal features.
• Z-direction suitability: Normal discs are not suitable for probing in the Z direction unless equipped with radius end rollers.
• Applications: Ideal for measuring large inside diameters and integrated undercuts in precision work.

This disc styli combination delivers repeatable, accurate contact in challenging bore environments while offering straightforward mounting and durable construction. The 30 mm ball diameter provides practical reach for interior measurements, and the stainless steel body stands up to frequent use in calibration and inspection routines across manufacturing, aerospace, and automotive applications.
