ITP Straight Styli - Type A with a ruby ball is a precision probing stylus designed for everyday metrology tasks. It’s built for engineers and labs that require reliable rigidity and repeatable measurements in standard probing setups.

• Model/Design: Straight Stylus, Type A, for everyday standard use
• Overall length: 78 mm
• Thread: M4 external thread for secure mounting
• Stem material: Carbide for exceptional rigidity and long-term stability
• Tip: Ruby ball, high-quality, available in Ø1.0 mm to Ø8.0 mm
• Installation: Hand-tightened with SW5.5 open-end spanner
• Customization: Other sizes can be requested via configurator or by e-mail

With its carbide core and ruby ball, this stylus minimizes deflection under load to deliver stable contact geometry across measurements. The 78 mm length supports a wide range of probing geometries, while the M4 thread ensures quick, secure compatibility with standard probing heads. The ruby ball reduces wear on workpieces and maintains consistent contact radii, extending stylus life and reducing downtime. Hand-tightened installation provides a reliable setup without complex assembly. For applications needing alternate ball sizes or bespoke configurations, the configurator and email option enable precise tailoring while preserving reliability.
