The ITP Disc Styli stainless steel Prob Ball with a 15 mm diameter and M5 thread is a precision probing accessory designed for measuring large internal diameters and undercuts. Built for metrology professionals, this Type O configuration delivers stable, repeatable contact in challenging interior features.

• Material: Stainless steel construction for durability and corrosion resistance in shop environments.
• Ball diameter: 15 mm spherical tip provides reliable, consistent contact on large interior surfaces.
• Thread: M5 mounting thread for secure, quick attachment to compatible stylus holders.
• Design: Type O disc-style probe optimized for internal diameter measurements and undercuts.
• Intended use: Enables accurate measurement of large inside diameters and integrated undercuts where standard disks struggle.
• Direction note: Normal disks are unsuitable for probing in the Z direction unless discs with radius end rollers are used.

This disc-style probing solution supports precise data capture in complex internal geometries, helping you reduce measurement inspection time and improve part conformity. Its robust stainless steel build, combined with a substantial 15 mm ball, delivers durable performance across repeated tool changes and diverse workholding setups. The M5 thread ensures compatibility with a wide range of stylus holders, making it a practical addition to any CMM or handheld probing workflow. Designed for accuracy-focused environments such as manufacturing, aerospace, automotive, and mold making, it helps you achieve reliable results on challenging features without compromising on setup efficiency.
