The ITP Disc Styli stainless steel Prob Ball is a precision spherical disc probe designed for measuring large inside diameters and complex undercuts. With a 40 mm ball diameter and M5 mounting thread, it delivers reliable, repeatable probing in demanding metrology environments.

• Model: Type N spherical disc stylus, KIM504040080
• Material: Stainless steel for durability and corrosion resistance
• Ball Diameter: 40 mm spherical tip for accessing large internal features
• Thread: M5 mounting thread for easy integration with standard probe holders
• Applications: Ideal for measuring large inside diameters and integrated undercuts
• Direction Note: Not designed for probing in the Z direction with standard discs (radius end rollers are an exception)

The disc’s sizeable 40 mm ball enables stable contact inside roomy bores and recesses, reducing edge interference and measurement uncertainty. Stainless steel construction ensures longevity in workshop and inspection settings, while the compact M5 thread simplifies mounting on common metrology setups. This stylus supports precise, repeatable interior geometry measurements, helping streamline inspection workflows for components with large ID features and complex internal features.
