The ITP Disc Styli are precision spherical-disc probes designed for engineers and metrology specialists who measure large interior features with high accuracy. This stainless-steel Type M model, KIM201518M20, features an M2 thread and an 18 mm ball diameter, making it ideal for challenging inner diameters and undercuts.

• Material: Stainless steel construction for durability and corrosion resistance.
• Disc design: Solid machined base with a raised post for stable alignment.
• Ball diameter: 18 mm spherical tip provides reliable contact on larger internal features.
• Thread: M2 male thread on the post for quick, secure attachment to compatible equipment.
• Type: Type M spherical-disc probe optimized for interior measurements.
• Intended use: Ideal for measuring large inside diameters and integrated undercuts where flat disks underperform.
• Z-direction note: Normal disks are not suitable for probing in the Z direction, unless using radius-end-roller variants.

By pairing a sturdy stainless-steel body with a generous 18 mm ball and a precise M2 thread, this disc styli solution delivers repeatable contact on complex interiors, reducing setup time and boosting measurement reliability. It enables accurate capture of features in large bores and undercuts that would be difficult with smaller tips or flat disks. The Type M configuration offers predictable behavior in rough or feature-rich interiors, helping technicians minimize retries and improve workflow efficiency. Remember the Z-direction guidance: for vertical probing demands, consider specific end-roller variants designed for those tasks.
