Description
The ITP Straight Styli Type A with Ruby Ball is a high-precision probing stylus designed for everyday measurement tasks. Built for metrology professionals, it combines a rigid carbide stem with a quality ruby ball to deliver reliable, repeatable contact during CMM probing.
- Type: Straight stylus for standard use
- Material: Carbide stem for exceptional rigidity and minimal deflection
- Ruby ball range: Ruby balls from Ø2.0 mm to Ø10.0 mm; other sizes can be requested via configurator or by email
- Ball quality: High-quality ruby ball for wear resistance and stable contact
- Thread: M5 thread for secure attachment to compatible probes
- Overall length: 100 mm
Designed to improve measurement reliability across a range of feature sizes, this stylus minimizes deflection through its carbide spine, helping you achieve consistent results in precision probing. The ruby ball provides a hard-wearing, smooth contact that preserves tip geometry over many cycles, reducing replacement frequency. With a 100 mm reach and standard M5 threading, it fits a wide variety of probing setups for quick, repeatable scans. For specialized needs, sizes outside Ø2.0–Ø10.0 mm are available on request via the configurator or by email.
