ITP Disc Styli are precision spherical probing accessories designed for measuring large inside diameters and complex undercuts. This stainless steel Type M disc stylus with an M2 thread and an 18 mm ball diameter is built for reliability in demanding metrology tasks.

• Ball Diameter: 18 mm precision ball for stable, consistent contact on internal features
• Thread: M2 threaded stem for straightforward integration with compatible probes and fixtures
• Material: Stainless steel offering durability, rigidity, and corrosion resistance
• Type: Type M disc stylus designed for spherical-disc probing applications
• Application: Realizes measurements of large inside diameters and integrated undercuts
• Direction Consideration: Normal disks are unsuitable for probing in the Z direction unless discs with radius end rollers are used

This disc stylus delivers precise, repeatable contact on inner cylindrical surfaces and undercuts where traditional disks struggle. The 18 mm ball provides a broad contact footprint that enhances measurement stability, while the compact M2-threaded stem enables easy attachment to standard probing systems. Ideal for metrology tasks in mechanical, automotive, and aerospace components where internal geometries demand accurate, reliable probing. Use this spherical disc in setups that require consistent performance across repeated inspections and for achieving clean data in bore and pocket measurements.
