Description
The ITP Disc Styli stainless steel Prob Ball (Type M) is a precision spherical disc probe designed for metrology professionals who need to measure large inside diameters and integrated undercuts with high accuracy. With an M2-threaded stem and a 25 mm ball diameter, it provides reliable contact in challenging internal features.
- Material: Stainless steel construction for durability and corrosion resistance.
- Ball Diameter: 25 mm spherical ball offers stable contact on large internal features.
- Thread: M2 threaded stem for compatibility with standard probe interfaces.
- Type: Type M spherical disc probe (disc stylus) optimized for internal measurements and undercuts.
- Applications: Ideal for measuring large inside diameters and integrated undercuts where traditional probes struggle.
- Directional Note: Normal disks are unsuitable for probing in the Z direction unless used with radius end rollers.
- Part Number: KIM201525008 for precise ordering and cross-reference.
Benefits: This disc stylus design enables accurate, repeatable measurements in hard-to-reach internal geometries, reducing measurement uncertainty for large bore features and undercuts. The robust stainless steel body withstands routine workshop use, while the 25 mm ball diameter provides substantial contact area for stable readings. The compact M2 thread simplifies integration with common probing heads, helping you maintain efficient inspection workflows in CMM setups and precision machining environments.
