Description
The ITP Straight Styli Type A with Ruby Ball is a precision probing accessory designed for metrology and coordinate measuring systems. Built for everyday accuracy, it combines a carbide shaft, a titanium holder, and a ruby ball to deliver reliable, repeatable contact in tight measurement spaces.
- Thread: M3 XXT thread for secure mounting in compatible probing systems
- Overall Length: 30 mm, compact profile suited for limited-access areas
- Holder Material: Titanium Ø5.0 mm holder to balance stiffness and lightweight design
- Tip Material: Ruby ball available in high-precision sizes from Ø0.8 mm to Ø2.5 mm for durable, accurate contact
- Stem Material: Carbide shaft delivering exceptional rigidity and minimal deflection
- Customization: Further ruby ball sizes and configurations can be requested via the configurator or by email
This stylus is engineered to provide stable performance across routine inspection and calibration tasks. The rigid carbide stem minimizes bending under load, while the ruby ball offers long wear life and low friction for repeatable measurements. The titanium holder adds resistance to corrosion and keeps overall weight down, helping you sustain accurate probing over extended sessions. With a 30 mm length and a universal M3 XXT thread, it pairs smoothly with a wide range of probing arms and accessories. Ideal for precision work where small features or delicate surfaces require reliable contact and consistent results.
