ITP Disc Styli ceramic Prob Ball with M2 thread and a 4 mm ball diameter is a precision probing accessory designed for metrology professionals who measure large internal diameters and intricate cavities. Built for reliability, this Type O disc stylus combines a ceramic probing ball with a robust stem to deliver consistent, repeatable readings in demanding inspection tasks.

• Ball diameter: 4 mm spherical probing ball optimized for contacting curved interior surfaces and undercuts.
• Material: Ceramic ball mounted on a durable metal stem for excellent wear resistance and stable measurements.
• Thread: M2 mounting thread for secure, quick attachment to standard stylus holders.
• Shape/Type: Type O disc stylus designed to reach into recessed features while maintaining a compact profile.
• Applications: Ideal for measuring large inside diameters and integrated undercuts where flat probes struggle to reach.
• Probing direction note: Normal disks are unsuitable for probing in the Z direction unless using discs with radius end rollers; plan Z-axis probing accordingly.

This disc stylus excels in ensuring accurate spatial contact on challenging interior geometries, reducing measurement ambiguity and enabling repeatable results across batches. The ceramic ball minimizes wear and deformation, helping you sustain precision in repetitive inspection tasks. Its small M2 thread and sturdy construction make it a dependable choice for demanding metrology workflows that require consistent performance in tight or complex cavities.
