The ITP Straight Styli Type A with a silicon nitride ball is a precision probing stylus designed for everyday CMM measurements. With a 100 mm overall length and an M5 thread, it combines a rigid carbide stem with a wear-resistant ball to deliver consistent touch readings, including on untreated aluminum parts.

• Series: Type A (THM5S5011100)
• Overall length: 100 mm
• Connection: M5 thread for secure attachment to compatible probes
• Stem material: Carbide for exceptional rigidity
• Ball material: Silicon nitride, optimized for wear resistance and smooth contact
• Ball sizes: Ø1.5 mm to Ø10.0 mm available in this group
• Holder compatibility: Ø10.0 mm, Ø11.0 mm, and Ø12.0 mm holders
• Applications: Especially recommended for scanning untreated aluminum surfaces
• Custom sizing: Other sizes can be requested via configurator or by email

The combination of a carbide stem and silicon nitride ball minimizes measurement variability across a broad range of feature sizes, delivering repeatable results on a variety of parts. The silicon nitride ball’s hardness and low adhesion make it particularly well-suited for aluminum, helping to reduce wear on the ball and improve data quality over time. Its 100 mm reach makes it suitable for probing recessed features, edge radii, and tight pockets without compromising stability. For users upgrading existing CMM setups or designing new measurement programs, this stylus provides a reliable, long-lasting option that maintains tight tolerances through routine scanning tasks.
