Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for reliable, everyday metrology tasks. Built around a rigid carbide stem and topped with a high-quality ruby ball, it delivers repeatable contact and consistent results in tight tolerances.
- Tip type: Ruby ball probe tip, engineered for smooth, wear-resistant contact; available in diameters from 0.5 mm to 5.0 mm through the configurator or by email.
- Material: Carbide stem for exceptional rigidity and dimensional stability during probing.
- Thread: M2 thread for secure, compatibility-focused mounting with standard probing systems.
- Overall length: 20.25 mm, providing a compact, steady reach for precise measurements.
- Finish and branding: Precision-machined metallic finish with clear ITP branding for reliable identification in busy workspaces.
Designed for engineers, technicians, and quality-control professionals, this straight stylus minimizes deflection under load, helping you capture accurate measurements quickly. The carbide stem maintains stiffness across repeated cycles, while the ruby ball tip reduces wear and preserves surface integrity on a variety of workpieces. With configurable ruby ball diameters, you can tailor contact area and resolution to your inspection tasks, from fine feature probing to larger-diameter contact points. The result is a dependable, low-maintenance probing solution that integrates smoothly with common CMM and fixture-based systems.
