Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing accessory built for routine metrology tasks. Designed for technicians and engineers who value dependable, repeatable contact, this straight stylus pairs robust materials with proven performance.
- Thread compatibility: M5 thread for secure attachment to standard probe heads and quick swaps on the measurement bench.
- Tip material: Ruby ball tips available from Ø0.7 mm to Ø3.0 mm deliver hard, wear-resistant contact for consistent measurements.
- Stem construction: Carbide stem provides exceptional rigidity and dimensional stability across a wide range of dimensions.
- Overall length: 75.5 mm reach, offering extended access without compromising probe clearance in tight fixtures.
- Customization options: Additional ruby-ball sizes can be requested via the configurator or by email to match specific measurement scenarios.
This straight stylus helps reduce deflection and wear-induced drift, enhancing measurement reliability during everyday inspection, part verification, and fixture alignment. The combination of a rigid carbide stem and high-quality ruby-ball tips ensures smooth, repeatable contact even in challenging surfaces, while the 75.5 mm length provides handy reach for recessed features. If your application calls for a variation in tip size, ordering through the configurator or contacting support ensures you get the right geometry for your workflow.
