The ITP Disc Styli stainless steel Prob Ball, M2 thread x 18 mm ball diameter, Type M (model KIM202218M20), is a precision spherical disc stylus designed for measuring large inside diameters and integrated undercuts. Built for metrology professionals, it delivers reliable contact and repeatable results in challenging internal geometries.

• Material: Stainless steel for durability and corrosion resistance.
• Ball Diameter: 18 mm precision spherical probe ball for stable contact on larger features.
• Thread: M2 male thread for secure mounting on compatible probes.
• Type: Type M spherical disc stylus optimized for probing internal geometries.
• Application: Ideal for measuring large inside diameters and integrated undercuts where standard disks struggle.
• Z-Direction Guidance: Note that normal disks are unsuitable for probing in the Z direction (exceptions apply for discs with radius end rollers).
• Craftsmanship: Precision-machined surface ensures consistent contact and repeatable measurements.

This disc stylus enables accurate bore and cavity measurements without intrusive probes or repeated repositioning. The 18 mm ball provides a forgiving contact profile for interior features, while the robust stainless steel body with the M2 thread allows quick, repeatable setups on coordinate measuring machines and other metrology equipment. Ideal for quality control and inline inspection in manufacturing environments where reliable internal geometry measurement is essential.
