ITP Straight Styli Type A with Ruby Ball is a precision straight stylus built for everyday metrology tasks. Designed for reliable contact probing, it combines a carbide stem with premium ruby balls to deliver stable, repeatable measurements.
- Material and construction: Carbide stem delivers exceptional rigidity and long-term stability for accurate measurements across a wide range of dimensions.
- Ruby ball sizes: Premium ruby contact balls available from Ø2.0 mm to Ø10.0 mm, engineered for hard-wearing, low-friction contact.
- Thread and length: M5 threaded connection with a 53 mm overall length for secure mounting and compatibility with standard probing hardware.
- Configuration and sizing: Custom sizes can be requested via the configurator or by e-mail to suit specific measurement requirements.
- Design type: Straight stylus optimized for everyday standard use, ensuring straightforward setup and reliable readings.
These features translate into tangible benefits: strong resistance to deflection from the carbide stem yields consistent readings under routine probing; high-quality ruby balls minimize wear and provide repeatable contact across cycles; and the 53 mm length with M5 threading fits a wide range of CMM and probing setups. Ideal for standard inspection, calibration routines, and quality control workflows where dependable touch accuracy matters.
