The ITP Disc Stylus is a stainless steel spherical disc probe designed for precision interior measurements. Tailored for professionals working with large bores and integrated undercuts, this Type N disc delivers steady, repeatable contact in demanding inspection tasks.

• Material: Stainless steel construction for durability and corrosion resistance in busy workshop environments.
• Ball Diameter: 50 mm precision ball to reach and measure large interior diameters with stable contact.
• Thread: M5 threaded shank for secure mounting in compatible probe holders.
• Type: Type N spherical disc geometry optimized for interior features and undercuts.
• Applications: Ideal for measuring large bores, internal diameters, and recessed contours in mechanical parts.
• Z-Direction Compatibility: Normal discs are not suitable for probing in the Z direction unless used with radius-end rollers.
• Part Number: KIM505050080

In practice, this disc stylus helps you tackle challenging internal geometries with confidence. The generous 50 mm ball diameter provides a stable probing surface across curved interiors, while the robust stainless steel body stands up to repeated use in metrology workflows. The M5 mounting thread ensures quick, reliable integration with a wide range of probing systems, supporting consistent data collection for components such as engine housings, gearbox bores, and hydraulic parts. Plan for Z-direction probing limitations when selecting accessories, and consider radius-end rollers if your measurement setup requires probing along the Z axis.
