Description
The ITP Straight Stylus - Type A with Ruby Ball (NHM503011025) is a precision probing accessory designed for metrology workloads. Crafted for everyday accuracy, it combines a rigid carbide stem with a high-quality ruby ball tip and a convenient M5 mounting thread in a compact 25.5 mm overall length.
- Overall length: 25.5 mm for a compact, space-efficient probing tip.
- Thread: M5 male thread for quick, secure attachment to standard stylus holders.
- Stem material: Extremely rigid carbide for reduced deflection and durable performance.
- Tip: Ruby ball tip designed for precise contact; ball sizes range Ø1.0 mm to Ø5.0 mm.
- Custom sizing: Other ruby ball sizes can be requested via the configurator or by email.
This stylus is ideal for labs and workshops that require consistent, repeatable contact readings across a range of materials. The carbide stem minimizes bending under load, helping maintain accuracy during probing, while the ruby ball provides a hard, smooth contact surface that resists wear. The combination of a compact form factor and a standard M5 thread makes it compatible with a wide array of probing systems, enabling reliable performance in daily measurement tasks. If you need a non-standard ball diameter, you can request a custom size to tailor the touchpoint to your specific application.
