Description
The ITP Straight Stylus Type A with a ruby ball end is a precision probing accessory designed for metrology professionals who demand dependable, repeatable contact points in everyday inspection tasks. With a carbide stem and a compact 23 mm overall length, it delivers rigid performance and reliable measurements in tight spaces.
- Thread: M4 external thread for quick, secure mounting with standard probing systems.
- Overall length: 23 mm, providing a compact reach ideal for small features and recessed areas.
- End ball: Ruby ball finish for smooth contact, reduced wear, and excellent surface compatibility.
- Material: Carbide stem offers exceptional rigidity and minimal deflection under load.
- Ball diameter range: Available with ruby balls from Ø1.0 mm to Ø8.0 mm to suit different feature geometries.
- Assembly: Hand-tightened with an SW5.5 open-end spanner for secure, efficient setup.
- Custom sizes: Other ruby ball sizes can be requested via configurator or by email to tailor the stylus to your specific tasks.
This stylus is crafted to enhance measurement confidence: the stiff carbide shaft maintains alignment during probing, while the ruby ball provides a durable, low-friction contact that helps deliver consistent readings over time. Ideal for precise contact measurements on small features, edges, and tight cavities, it integrates smoothly with existing inspection setups and can be customized to match the exact geometry of your workpiece.
