ITP Straight Styli Type A with a silicon nitride ball (THM5S4011033) is a precision probing stylus designed for reliable, everyday CMM measurements. With a 33.5 mm overall length, M5 mounting thread, and a rigid carbide stem, it delivers stable contact in tight fixtures—especially when scanning untreated aluminum parts.

• Product code: THM5S4011033
• Thread: M5 mounting thread for secure, quick attachment to compatible probes
• Overall length: 33.5 mm profile optimized for access in restricted spaces
• Stem material: Carbide for exceptional rigidity and dimensional stability
• Ball material: Silicon nitride ball designed for wear resistance and smooth contact
• Ball size availability: Within this group, ball sizes range from Ø1.5 mm to Ø10.0 mm
• Holder compatibility (group): Group supports holders in Ø10.0 mm, Ø11.0 mm, and Ø12.0 mm

These design choices translate to more consistent measurements and longer service life, even with repeated probing on challenging materials. The silicon nitride ball is particularly well-suited for scanning untreated aluminum, helping minimize surface wear and maintain ball quality over time. If your needs evolve, other sizes can be requested via the configurator or by e-mail to tailor the stylus to your specific measurement setup.
