The ITP Straight Styli Type A with a ruby ball is a precision probing stylus built for metrology, inspection, and calibration tasks. Designed for technicians and machinists who demand reliable, repeatable contact, it pairs a rigid carbide stem with a high-quality ruby ball to deliver consistent measurements in a compact M5-threaded package.

• Thread & length: M5 thread with a 30.5 mm overall length for secure mounting in compatible probing systems.
• Material & construction: Carbide stem provides exceptional rigidity and dimensional stability under load, minimizing deflection during measurement.
• Ruby ball diameter range: Uses premium ruby balls in the range Ø0.7 mm to Ø3.0 mm for hard-wearing, precise contact.
• Design: Straight stylus geometry optimized for everyday standard use in routine measurements and inspections.
• Customization: Other ruby ball sizes can be requested via the configurator or by email to match specific measurement needs.

This stylus enables repeatable, reliable probing across a variety of features and surfaces. The combination of a rigid carbide stem and a high-quality ruby tip minimizes wear and drift, helping you achieve stable readings over time. Its compact form and standard M5 threading simplify integration into existing measurement setups, making it a practical choice for daily metrology work, calibration routines, and workshop inspections.
