Description
The ITP Straight Styli – Type J with Ruby Ball and M3 thread is a precision probing stylus designed for long-reach measurements in CMMs and machine probes. Crafted for engineers and technicians who demand minimal weight without sacrificing rigidity, it delivers stable, repeatable contact for high-accuracy data collection.
- Overall Length: 104 mm to reach recessed features and deep pockets with consistent probing
- Thread: M3 thread for secure compatibility with standard probe heads
- Stem Material: Carbon fiber stem for excellent stiffness-to-weight ratio and reduced deflection
- Ball Size: Ruby ball available in Ø6.0 mm to Ø12.0 mm for optimal contact and wear resistance
- Type: Type J configuration suited for long-reach styli in precision measurement setups
- Configurability: Other dimensions can be requested via the configurator or by email to match specific measurement needs
The design emphasizes lightweight yet rigid performance, making it ideal for probing challenging surfaces where traditional styli may bend or fatigue. The ruby ball’s high hardness and smooth finish ensure smooth deflection and durable wear characteristics, supporting reliable measurements over time. With its long reach and robust carbon fiber construction, this stylus helps you capture accurate dimensional data in hard-to-access regions, while maintaining compatibility with common probing systems through the standard M3 thread.
