Meet the ITP Straight Stylus Type A with a silicon nitride ball—designed for reliable, everyday probing in precision metrology. It’s ideal for technicians who measure aluminum parts and seek consistent, repeatable contact during surface scans.

• Thread: M5 thread for quick, secure attachment to compatible probes.
• Overall Length: 30 mm total length, offering reach into tight fixtures and recessed features.
• Stem Material: Carbide stem provides high rigidity to minimize deflection during probing.
• Ball Material: Silicon nitride ball for wear resistance and clean, consistent contact on challenging surfaces.
• Base Construction: Stainless steel base delivers stable mounting and repeatable performance.
• Ball Size Range: Part of a family that offers silicon nitride balls across a range suitable for various contact profiles (Ø1.5 mm to Ø10.0 mm commonly used in this group).

With a carbide stem and a silicon nitride ball, this stylus delivers consistent contact, reduced deflection, and long wear life—key for repeatable measurements across many parts. The 30 mm length provides reach into tight features, while the M5 thread aligns with a broad ecosystem of probing systems. Specifically advantageous for scanning untreated aluminum parts, silicon nitride reduces adhesion and wear, helping you achieve cleaner data and longer stylus life.
