The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus designed for metrology professionals who need reliable, repeatable contact in daily measurement tasks. Built around a rigid carbide stem and a high-quality ruby ball, it offers a compact 51 mm overall length and a secure M5 mounting thread for seamless integration with standard probes.

• Model and compatibility: ITP Straight Styli Type A with Ruby Ball, designed for everyday metrology use and compatible with common probing interfaces via M5 threading.
• Thread: M5 male thread for secure, quick mounting on compatible probes and fixtures.
• Stem material: Carbide stem delivers exceptional rigidity and minimal deflection under contact load.
• Ball tip: Ruby ball selected for hardness and smooth engagement, available in sizes ranging from Ø0.7 mm to Ø3.0 mm.
• Overall length: 51 mm, providing a balanced reach for typical CMM and inspection tasks.
• Customization: Other ball sizes can be requested via the configurator or by e-mail to suit specific measurement requirements.
• Usage: Straight stylus optimized for standard probing workflows and everyday measurement tasks.

In practice, the carbide stem minimizes bending and maintains consistent contact force across surfaces, while the ruby ball delivers a precise, smooth touch that reduces wear on both the probe and tested parts. The 51 mm length strikes a practical balance between reach and maneuverability, making it suitable for surface profiling, edge measurements, and fixture alignment in busy lab environments. If your applications require a different ball radius, you can easily request an alternative size through the configurator or by e-mail to ensure you have the exact contact geometry for your inspection routines.
