- Thread: M5
- Overall length: 30 mm
- Ball material: Silicon nitride for durability and low wear during scans
- Stem material: Tungsten carbide providing exceptional rigidity and minimal deflection
- Tip style: Straight stylus with a spherical ball for consistent contact
- Ideal use: Suitable for general measurements and scanning, with particular effectiveness on untreated aluminum
- Custom sizes: Other lengths and ball sizes can be requested via configurator or by email
This stylus is engineered to maintain geometry under load, helping you achieve stable contact, cleaner data, and longer tip life. The silicon nitride ball behaves well on a range of surfaces, including untreated aluminum, reducing marring while producing reliable measurement data.
