ITP Straight Styli - Type A with Ruby Ball is a high-precision probing stylus designed for metrology professionals who need a lightweight, rigid solution for long-reach measurements. Its carbon fibre stem and ruby ball tip deliver consistent, repeatable contact in challenging measurement scenarios.

• Thread: M4 threaded connection for broad compatibility with common probing heads and extensions.
• Tip material: Ruby ball available in diameters from Ø3.0 mm to Ø12.0 mm, providing hard, wear-resistant contact for stable measurements.
• Stem material: Carbon fibre stem delivers low weight and high rigidity to minimize deflection during probing.
• Overall length: 103 mm total length offers extended reach while maintaining stiffness for precise touch points.
• Design: Straight stylus geometry ensures predictable contact geometry and repeatable results across measurement cycles.
• Customization: Other dimensions can be requested via the configurator or by email to tailor the tool to your equipment and application.

This stylus combines lightweight efficiency with structural rigidity to reduce bending under load, helping you achieve higher accuracy in CMM, machine probing, and precision measurement workflows. Ruby ball tips provide durable, smooth contact with minimal wear, supporting reliable performance over many cycles. With a 103 mm reach and standard M4 threading, it's a versatile choice for a wide range of probing setups. For dimensions beyond the listed options, use the configurator or email to request a custom specification.
