The ITP Straight Styli Type A with a silicon nitride ball is a precision probing accessory designed for routine metrology tasks on CMMs and scanning setups. Built for professionals who demand dependable rigidity and repeatable data, it combines a carbide stem with a hardened silicon nitride ball to deliver reliable measurements on challenging surfaces such as untreated aluminium.

• Thread and length: M5 thread; 100 mm overall length for easy integration with standard probe heads.
• Stem material and rigidity: Carbide stem provides exceptional rigidity, minimizing deflection across a broad range of measurement dimensions.
• Ball material: Silicon nitride ball offers high hardness, wear resistance, and smooth engagement with metal surfaces, especially untreated aluminium.
• Holder compatibility: Compatible with common holder options in this group, including Ø10.0 mm, Ø11.0 mm, and Ø12.0 mm variants.
• Ball size range: Ball diameters available in this family span Ø1.5 mm to Ø10.0 mm, enabling precise contact points for different features.
• Customization: Other sizes can be requested via the configurator or by e-mail.

With its rigid carbide stem and durable silicon nitride ball, this stylus delivers stable, repeatable measurements across repeated cycles and various part geometries. The silicon nitride ball reduces wear on aluminium surfaces, minimizing data variability and extending stylus life. The 100 mm length provides reach for measuring taller features or recessed pockets, while the M5 thread ensures seamless compatibility with a wide range of probing systems. Whether you’re performing quick in-process checks or high-precision inspections, this stylus helps capture accurate touchpoints and clean data for reliable dimensioning and quality control.
