ITP Straight Styli Type A with a silicon nitride ball delivers precise, lightweight probing for long-reach measurements. Designed for metrology professionals using CMMs, this stylus blends extreme rigidity with a compact form to optimize scanning of aluminum workpieces.
- M3 XXT thread: Secure, repeatable attachment to compatible probing systems for reliable data capture.
- 50 mm overall length: Long reach that accesses tight features while maintaining stiffness and stability.
- Silicon nitride ball tip: Hard, wear-resistant contact ideal for scanning untreated aluminium surfaces.
- Carbon fibre stem: Ultra-lightweight yet rigid construction minimizes deflection and improves probing dynamics.
- Material and craftsmanship: Precision-machined components with a robust build designed for consistent performance in metrology workflows.
- Custom dimensions: Other lengths or configurations available on request via configurator or email.
This stylus is especially effective for aluminum workpieces, where the silicon nitride tip reduces wear and maintains measurement fidelity over repeated scans. Its combination of low mass and high rigidity helps deliver cleaner data during rapid probing sequences, while the long reach expands access to features that are hard to reach with standard-length styli. For teams needing tailored setups, additional dimensions can be configured to fit specific inspection routines without compromising the proven performance of the Type A design.
