ITP Straight Styli – Type D with a ruby ball is engineered for precision tactile probing in metrology. Designed for professionals who need reliable, repeatable measurements, it combines a rigid tungsten carbide stem with a compact 32 mm overall length and an M5 mounting thread.

• Geometry: Straight Type D design with a stepped reinforced body for enhanced rigidity during probing.
• Material: Tungsten carbide stem delivers exceptional stiffness and wear resistance for long-term accuracy.
• Ruby ball sizes: High-quality ruby contact balls available from Ø0.2 mm to Ø1.0 mm to match your feature size.
• Thread and length: M5 thread compatibility and a 32 mm overall length for easy integration with standard probing heads.
• Configurability: Other dimensions can be requested via the configurator or by e-mail.

The combination of a hard tungsten carbide stem and ruby ball minimizes deflection and wear, ensuring stable measurements across repeated cycles. The ruby ball provides a durable, low-friction contact surface that preserves both the stylus and the workpiece. With its compact form and standard M5 thread, this Type D straight stylus fits seamlessly into existing CMM setups and micro-measurement rigs, enabling quick changes without sacrificing accuracy. Ideal for inspecting micro-machined parts, electronics components, and precision assemblies, it delivers consistent tactile feedback and trustworthy data for high-confidence results.
