The ITP Disc Styli stainless steel Prob Ball with M5 thread and a 10 mm ball diameter is a precision probing accessory designed for challenging internal measurements. Built for metrology professionals, it delivers a reliable contact point for disc-style probing in demanding geometries.

• Material: Stainless steel for durability and corrosion resistance in shop environments.
• Thread: M5 external thread for secure, straightforward mounting on compatible probes.
• Ball diameter: 10 mm spherical probe ball provides stable contact on large internal features.
• Type: Type M configuration optimized for disc-style probing applications.
• Application: Ideal for measuring large inside diameters and integrated undercuts where traditional disks struggle.
• Z-direction note: Normal disks are unsuitable for probing in the Z direction unless discs with radius end rollers are used.

This disc styli design directly supports accurate measurements of substantial internal geometries and undercut regions, where a larger contact area and robust construction make the difference between repeatable results and uncertain data. The 10 mm ball promotes stable, repeatable contact across varying bore shapes, while the stainless steel body stands up to routine use in calibration and inspection workflows. The M5 threading ensures a straightforward, secure mount, facilitating reliable setup in your probing station. For vertical (Z-axis) probing scenarios, consider the placement and tooling guidance associated with discs designed for that direction to ensure optimal performance.
