Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for metrology and CMM work. Built for everyday standard use, it combines a rigid carbide stem with high-quality ruby balls to deliver reliable, repeatable contact measurements.
- Thread: M5 thread for secure attachment to standard probing systems.
- Overall Length: 40 mm for compact, versatile use in tight fixtures.
- Stem Material: Carbide for exceptional rigidity and dimensional stability during probing.
- Ball End: Ruby ball available in high-quality sizes from Ø2,0 mm to Ø10,0 mm for precise contact.
- Quality Assurance: Ruby balls of the highest quality used to ensure durable, low-friction contact surfaces.
- Custom Sizing: Other sizes can be requested via configurator or by e-mail to fit specific measurement needs.
- Model / Code: THM503011040
This stylus is ideal for technicians and engineers performing routine inspections, calibration checks, and feature probing on a variety of materials. The carbide stem minimizes deflection under load, helping maintain measurement accuracy across repeated cycles, while the ruby ball provides a smooth, wear-resistant contact point for long-term reliability. If you require sizes beyond the Ø2,0 mm to Ø10,0 mm range, custom options are available upon request, ensuring you get the exact tip geometry you need for your application.
