The ITP Straight Styli Type A with a Ruby Ball is a precision probing stylus designed for everyday metrology tasks. Built around a carbide stem for exceptional rigidity, it pairs a high-quality ruby ball with a compact 21.5 mm overall length for reliable, repeatable measurements.

• Thread: M4 threaded shank for secure mounting on standard probe heads and fixtures.
• Ball end: Ruby ball tip—hard, wear-resistant contact suitable for precise scanning and edge measurements; available in sizes Ø1,0 mm to Ø6,0 mm, with custom sizes offered on request.
• Stem material: Carbide for stiffness and dimensional stability under probing forces.
• Overall length: 21.5 mm, compact profile ideal for tight spaces and hard-to-reach features.
• Customization: Other ruby ball sizes can be requested via the configurator or by email.

This straight stylus delivers dependable performance for routine dimensional checks, datum establishment, and feature probing. The combination of a rigid carbide stem and a durable ruby ball minimizes deflection and wear, enhancing measurement consistency over time. Its M4 mount and concise length make it a practical choice when access is limited or detailed surface contact matters. If your measurements require a different ball diameter, you can tailor the tool by selecting another size through the configurator or by contacting support for a custom option.
