Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for everyday metrology tasks. Built for professionals who need reliable, repeatable contact, it combines a rigid carbide shaft with a wear-resistant ruby ball for consistent measurements. Part number THM501011030/0,8.
- Thread: M5 mounting thread for compatibility with standard probes, fixtures, and holders
- Overall length: 30 mm for a compact, subtly profiled tip that fits into tight measurement areas
- Stem material: Extremely rigid carbide to minimize deflection and improve probing stability
- Ball end: Ruby ball contact surface, used across sizes from Ø1.0 mm to Ø5.0 mm; other sizes can be requested via the configurator or by email
- Design: Straight stylus geometry to ensure direct, linear probing and predictable contact behavior
The combination of a stiff carbide stem and a durable ruby ball translates into stable, repeatable measurements even during high-frequency probing or when scanning small features. The ruby ball provides a hard, smooth contact that resists wear and minimizes surface damage on delicate workpieces. The standard 30 mm length and M5 thread simplify integration with common probing systems, enabling quick tip changes and minimal setup time. If your applications demand different ball diameters, additional sizes can be configured to tailor the stylus to your feature size, surface finish, and inspection workflow.
