The ITP Disc Styli stainless steel Prob Ball is a precision spherical disc probe designed for reliable measurement of large inside diameters and integrated undercuts. It’s ideal for metrology work with coordinate measuring machines (CMMs) and inspection setups, offering robust mounting and stable contact with a 20 mm ball.

• Ball Diameter: 20 mm ball provides ample contact area for stable readings on large internal features.
• Thread: M5 male thread enables secure, quick mounting into compatible probe heads or holders.
• Material: Stainless steel construction delivers durability, wear resistance, and corrosion resistance in demanding environments.
• Geometry: Type N spherical disc design optimized for accessing large inside diameters and integrated undercuts.
• Application Focus: Specifically suited for inside-diameter measurement tasks where standard disks fall short; note that normal disks are unsuitable for probing in the Z direction unless used with radius end-roller variants.
• Part Number: KIM504020M50 for precise ordering and compatibility tracking.

This disc stylus delivers consistent, high-precision contact geometry that helps you capture true dimensional data in challenging interiors. The combination of a generous 20 mm ball and robust stainless steel construction minimizes wear while maintaining accuracy across repeated scans. The M5 thread keeps integration straightforward with common probe systems, helping you reduce setup time and keep your measurement workflow efficient. Ideal for aerospace, automotive, and tooling components where inner bore verification and undercut features are critical, the ITP Disc Styli Type N delivers dependable performance when you need it most.
