The ITP Straight Styli Type A with Ruby Ball is a precision tactile stylus designed for production metrology. It combines a carbide stem, a protective break point, and a high-quality ruby ball to deliver reliable, repeatable measurements in demanding manufacturing environments.

• Thread type: M3 thread for secure attachment to standard probing heads.
• Overall length: 42.5 mm overall length for compact, accessible measurements.
• Tip material: Ruby ball tip for durable, low-wear contact with workpieces.
• Ruby ball sizes: Ruby balls used on these styli range from Ø4.0 mm to Ø8.0 mm for different contact needs.
• Stem material: Carbide stem provides rigidity and long service life in production environments.
• Protection feature: Integrated break point protects the measuring system from accidental collisions.
• Customization: Other dimensions can be requested via the configurator or by email.

Designed for reliability in calibration, inspection, and routine gauging, this stylus offers a stable contact point with excellent wear resistance thanks to the carbide stem and ruby ball. The break point minimizes downtime by absorbing impacts that could otherwise damage sensitive measuring heads, while the standard M3 connection ensures compatibility with a wide range of fixtures. For specific measurement tasks, the Ø4.0–Ø8.0 mm ruby ball options provide the right balance between contact area and precision, helping you achieve consistent repeatability across production checks and first-article inspections.
