The ITP Straight Styli Type A with a silicon nitride ball is a precision probe built for everyday metrology work. With a rigid carbide stem and a compact 42 mm overall length, it delivers stable, repeatable readings for CMM probing and surface scanning—especially on aluminum parts.
- Thread: M5 threaded connection for secure attachment to standard probing heads.
- Overall length: 42 mm, providing a compact profile for reaching tight features.
- Stem material: Extremely rigid carbide spine to minimize deflection during contact.
- Ball material: Silicon nitride ball designed for durable, low-wear contact—particularly recommended for scanning untreated aluminium parts.
- Ball sizes in group: Available from Ø1.5 mm to Ø10.0 mm; other sizes can be requested via configurator or by email.
Designed for reliable performance in daily inspection workflows, this stylus balances rigidity, precision, and compatibility. The silicon nitride ball reduces wear on aluminum surfaces, helping to preserve measurement accuracy over time while maintaining smooth, consistent contact geometry. The 42 mm length and M5 thread make it a versatile choice for a wide range of measurement tasks, from feature probing to surface mapping. If you need a specific ball size beyond standard options, you can request it through the configurator or by email, ensuring you have the right contact geometry for your application.
