The ITP Disc Styli ceramic Prob Ball with M2 thread and 8 mm ball diameter is a precision probing accessory designed for metrology professionals who measure large internal diameters and complex undercuts with confidence. Built for durability and stable contact, this Type O disc stylus fits seamlessly into standard probe setups for reliable bore measurements.

• Material: Ceramic ball mounted on a robust steel shank for wear resistance and consistent performance.
• Ball Diameter: 8 mm ball suitable for accessing larger internal features.
• Thread: M2 male thread for quick, secure attachment to common stylus holders.
• Disc Type: Type O design optimized for accurate contact on spherical discs in bore measurements.
• Applications: Ideal for measuring large inside diameters and features with integrated undercuts where standard disks struggle.
• Z-Direction Note: Normal disks are unsuitable for probing in the Z direction; discs with radius end rollers are recommended if Z probing is required.
• Product Code: KKM208003032 for easy identification and cataloging.

Using this ceramic Prob Ball disc stylus delivers precise, repeatable readings in challenging internal geometries. The ceramic material provides wear resistance for longer tool life, while the 8 mm ball diameter enables access to larger bores without sacrificing contact quality. The M2 threading integrates smoothly with existing probe assemblies, making it a practical upgrade for quality control routines, aerospace and automotive bore checks, and general manufacturing inspections. By choosing this disc stylus, you gain reliable data, reduced setup time, and better consistency across measurement sessions, enabling more accurate assessments of internal diameters and undercut features.
