The ITP Straight Stylus Type A with a silicon nitride ball is a precision tapping accessory designed for everyday metrology tasks. Built for professionals who require rigidity, reliability, and smooth contact during probing, it excels in scanning and tactile measurement workflows.

• Model / Part Number: THM5S2011020/K
• Ball material: Silicon nitride ball delivers excellent hardness and wear resistance, ideal for scanning on metal surfaces, including untreated aluminium
• Stem construction: Extremely rigid carbide stem minimizes deflection to maintain accuracy across a wide range of dimensions
• Thread: M5 external thread for secure, quick attachment to probes and extensions
• Overall length: 20 mm, providing a compact profile with stable balance for precise measurements
• Family ball sizes: Part of a range that includes ball options from Ø1.5 mm to Ø10.0 mm to fit different measurement needs
• Holder compatibility: Group offers standard holders in Ø10.0 mm, Ø11.0 mm, and Ø12.0 mm to suit various measuring systems

This straight stylus is purpose-built to improve measurement consistency and tool life. The combination of a silicon nitride ball and a rigid carbide stem reduces wear on workpieces and minimizes deflection, helping you achieve repeatable results whether you’re inspecting components, validating tolerances, or documenting surface profiles. If you require a different ball size to match a specific application, sizes outside this configuration are available through the configurator or by email.
