The ITP Straight Styli Type A with a silicon nitride ball is a robust, straight stylus designed for routine CMM measurements, especially when scanning untreated aluminum parts. Its carbide stem delivers exceptional rigidity, ensuring precise, repeatable contact across a range of probing tasks.

• Part Number: THM2S3003051
• Ball Size Range: Ball diameters from Ø1.0 mm to Ø5.0 mm are available in this Type A configuration, letting you choose the contact size that suits your feature and material.
• Ball Material: Silicon nitride ball for high hardness, wear resistance, and stable surface contact during scans.
• Stem Material & Rigidity: Carbide stem provides exceptional stiffness to minimize deflection and improve data accuracy.
• Thread & Length: M2 thread with a total length of 51.5 mm for reliable coupling with standard measurement heads and accessories.
• Ideal For: Particularly well-suited for scanning parts made from untreated aluminum, where surface properties can influence data quality.
• Customization: Other ball sizes or configurations can be requested via the configurator or by email to tailor the stylus to your workflow.

The combination of a rigid carbide stem and a silicon nitride ball minimizes deflection under probing forces, delivering consistent, high-quality measurement data. Silicon nitride’s wear resistance helps extend stylus life and maintain accurate contact with aluminum surfaces, while the 51.5 mm reach provides stable access to recessed features and tight geometries—making this stylus a reliable choice for everyday measurement routines.
