Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for metrology professionals who need a lightweight, rigid contact point for CMM measurements. It delivers reliable, repeatable performance for everyday inspection tasks with a focus on accuracy and ease of use.
- Stem material: High‑performance ceramic stem offers low weight and exceptional rigidity for stable probing.
- Ruby ball sizes: High-quality ruby spheres available from Ø4.0 mm to Ø8.0 mm to match different measurement needs.
- Thread and length: M4 threaded tip with an overall length of 79 mm for secure mounting and comfortable handling.
- Product type: Straight stylus optimized for standard, routine metrology applications.
- Customization options: Other ruby‑ball sizes can be requested via configurator or by e‑mail to tailor to specific tasks.
This ruby‑ball stylus combines a lightweight yet stiff ceramic body with precisely formed ruby balls to deliver consistent contact points and minimize deflection during probing. The M4 thread ensures quick, secure installation on compatible probes, while the 79 mm length provides a practical reach for measuring edges, features, and small cavities. Ideal for measuring machined parts, fixtures, and assemblies, it helps you achieve reliable results and extend probe life by reducing tip wear.
