The ITP Straight Stylus Type A with a ruby ball is a precision probing accessory designed for everyday, standard measurement tasks. Built for reliability in metrology and probing setups, it delivers consistent contact in tight or intricate spaces.

• Tip material: Ruby ball tips of the highest quality, available in diameters from Ø1.0mm to Ø6.0mm for accurate, wear-resistant contact.
• Stem material: Carbide stem provides exceptional rigidity to maintain precise readings across a wide range of dimensions.
• Thread: M4 mounting thread for secure, compatible attachment to probing heads and fixtures.
• Overall length: 20.5mm overall length, designed for compact probing in confined work areas.
• Size options: Other ruby-ball sizes can be requested via the configurator or by email.

This combination of a rigid carbide stem and high-quality ruby ball delivers stable, repeatable measurements with minimal deflection. The compact 20.5mm length and M4 threaded interface make it a practical choice for coordinating with standard probing systems, enabling precise inspections of small features, edges, and micro-geometries. Ideal for technicians and engineers performing routine metrology, fixture verification, and quality checks across a range of parts and assemblies.
