The ITP Straight Styli Type C with a ruby ball is a precision tactile stylus designed for metrology and inspection work, built for reliability in CMM probing and probing-system setups.

• Interface: M5 thread for secure mounting into standard probing assemblies.
• Body design: Straight, stepped, and hardened construction to maximize rigidity and stability during measurement.
• Tip material: Ruby ball used for durable, consistent contact and low wear over time.
• Ball size range: Available with ruby balls from Ø1.35 mm to Ø2.5 mm to suit different feature sizes.
• Stem material: Tungsten carbide stem delivering exceptional rigidity and wear resistance.
• Overall length: 32 mm, compact profile that fits a variety of probing arms and geometries.
• Custom sizes: Other sizes can be requested via the configurator or by email.

This stylus helps deliver repeatable, accurate measurements by minimizing deflection under load and providing a stable contact surface. The tungsten carbide stem resists wear for longer service life, while the ruby ball provides a durable, low-friction contact that maintains consistent results across measurement cycles. Its compact 32 mm length and M5 threaded interface make it a practical choice for tight work envelopes and a wide range of inspection tasks—from precise edge detection to feature verification in metalworking, electronics, and automotive applications.
