The ITP Disc Styli stainless steel Prob Ball with M5 thread and a 15 mm ball diameter is a precision probing solution designed for measurement specialists who need reliable access to large inside diameters and integrated undercuts. Ideal for use with coordinate measuring systems, this Type O stylus delivers consistent contact in challenging interior features.

• Material: Stainless steel for durability, corrosion resistance, and stable probe performance in workshop environments.
• Ball Diameter: 15 mm ball provides robust, repeatable contact for larger bores and curved interior surfaces.
• Thread: M5 threading for secure, easy attachment to standard probe heads and fixtures.
• Disc Geometry: Spherical disc section crafted to reach into interior features and undercuts without compromising measurement accuracy.
• Designation: Type O with a compact, efficient profile suitable for inside diameter measurements.
• Application Notes: Specifically useful for measuring large inside diameters and integrated undercuts; normal disks are not suitable for Z-direction probing unless using discs with radius end rollers.

This disc stylus empowers precise interior measurements in applications such as bore checks, sleeve and hub inspections, and cavity geometry verification. The combination of stainless steel construction, a 15 mm ball, and a secure M5 mount supports accurate data collection with minimal setup, helping you achieve repeatable results across multiple parts and batches. For best results, pair with compatible probing routines and fixtures designed for interior geometry assessment.
