ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for everyday metrology tasks. Its carbide stem delivers exceptional rigidity, paired with a high-quality ruby ball for reliable, repeatable contact in CMM and inspection workflows.

• Part number: THM501512028
• Thread: M5 thread for secure mounting with standard probing interfaces
• Overall length: 28.75 mm for a compact, easy-to-handle profile
• Ball size range: Ruby balls from Ø1.5 mm to Ø8.0 mm to fit a variety of features
• Ball material: Ruby (corundum) for exceptional hardness and wear resistance
• Stem material: Carbide for extreme rigidity across a wide range of dimensions
• Customization: Other sizes can be requested via the configurator or by email

This straight stylus is ideal for routine measurements on flat or gently curved surfaces, small features, and controlled-depth probing. The rigid carbide core minimizes deflection under load, helping you achieve consistent, repeatable data. The ruby ball offers a hard, wear-resistant contact surface, extending the stylus’s service life between replacements. If your application requires a different ball diameter, you can request alternate sizes through the configurator or by email, ensuring you have the right contact geometry for your specific task.
