The ITP Disc Styli stainless steel Prob Ball is a precision spherical-disc probe for metrology professionals who measure large inside diameters and undercuts. It features a durable stainless steel body with a 30 mm ball diameter and an M5 mounting thread for versatile integration with standard probe heads.

• Material: Stainless steel for durability and corrosion resistance in demanding shop environments.
• Thread: M5 mounting thread provides compatibility with common probe heads and fixtures.
• Ball diameter: 30 mm ball diameter optimizes contact footprint for large bore measurements.
• Type: Type N design within the ITP disc-styli family.
• Primary use: Ideal for measuring large inside diameters and integrated undercuts.
• Probing direction note: Normal disks are unsuitable for probing in the Z direction unless equipped with radius end rollers.

This spherical disc configuration enables accurate bore geometry capture in challenging geometries, delivering repeatable measurements that help you verify tolerances and assess part quality. The 30 mm ball provides a stable contact point for large-diameter measurements while maintaining gentle contact to minimize part deformation. The stainless steel construction ensures longevity in busy inspection environments, and the M5 thread allows quick, secure mounting on conventional CMM setups. Use this disc for applications in automotive, aerospace, and tooling where reliable inside-diameter and undercut measurements are essential.
