Description
ITP Straight Styli - Type A with Ruby Ball (THM503511075) is a precision touch probe accessory designed for everyday measurement tasks. Featuring a carbide stem and a high-quality ruby ball, it’s built for reliability and repeatable results in standard probe setups.
- Overall length: 75 mm from tip to the base, providing reliable reach for many probing tasks.
- Thread: M5 male thread for quick, secure mounting in common probe holders.
- Stem material: Carbide for exceptional rigidity and dimensional stability under load.
- Ball material: Ruby ball, offering a hard, smooth contact surface for accurate measurements.
- Ball size options: Ruby balls available from Ø2.0 mm to Ø10.0 mm; other sizes can be requested via the configurator or by e-mail.
- Design: Straight stylus optimized for everyday standard use with consistent contact geometry.
This combination of a rigid carbide stem and a high-quality ruby ball delivers repeatable contact accuracy, reduced wear on both the stylus and mounting hardware, and dependable performance across a range of measuring scenarios. The 75 mm length provides comfortable reach for features with limited access, while the M5 thread supports quick integration into existing probe assemblies. If your application requires a different tip diameter, you can request a custom size through the configurator or by e-mail, ensuring you have the exact geometry you need for precise metrology tasks.
