The ITP Disc Stylus, model KIM504020080, is a stainless steel spherical disc probe designed for precision metrology. With a 20 mm probing ball and an M5 thread, it’s built to tackle measurements of large inside diameters and integrated undercuts in CMM workpieces.

• Material: Stainless steel for durability, wear resistance, and corrosion resistance in demanding environments
• Ball Diameter: 20 mm provides stable contact on large internal features
• Thread: M5 threaded shank for secure, compatibility-friendly attachment
• Disc Type: Type N spherical disc stylus designed for interior measurements and undercuts
• Primary Use: Ideal for measuring large inside diameters and recessed features where precision is critical
• Z-Direction Consideration: Not recommended for probing in the Z direction with standard disks; radius-end-roller variants are required for Z probing
• Compatibility: Designed to integrate with standard probe heads and metrology setups that accept M5 stylus attachments

This disc stylus delivers reliable, repeatable data for internal diameters and complex geometries, making it a valuable accessory for quality control, aerospace and automotive components, and precision engineering projects. The robust stainless steel construction supports repeated use in production environments, while the 20 mm ball geometry expands the range of features you can accurately capture. Its secure M5 threading ensures quick, tool-free changes on compatible CMM systems, helping minimize downtime during audits or routine inspections. For best results when probing deep bores or undercuts, pair with appropriate Z-direction tooling or radius-end roller options designed for those applications.
