ITP Straight Styli — Type B with Ruby Ball is a compact, reliable probing solution for precision measurement tasks. Built for engineers and technicians, it combines a rigid tungsten carbide stem with high-quality ruby contact tips to deliver consistent results in everyday use. Model NHM501011022 features an M5 thread and a 22.5 mm overall length for easy integration with standard probe setups.

• Thread: M5 thread for secure attachment to standard probe heads
• Overall length: 22.5 mm
• Stem material: Tungsten carbide, offering exceptional rigidity and wear resistance
• Contact tip: Ruby ball available from Ø0.2 mm to Ø1.5 mm for precise, smooth contact
• Stem configuration: Straight stem that can be single- or multi-stepped depending on configuration
• Custom sizing: Other sizes can be requested via the configurator or by e-mail

This stylus is engineered to improve measurement consistency across a range of small-scale applications. The ultra-rigid tungsten carbide stem minimizes deflection during contact, helping to achieve repeatable results even in tight spaces. The ruby ball tips combine hardness and a smooth surface finish, reducing wear on both the stylus and the workpiece while enabling accurate tracing of fine features. With a short, practical length and a universally compatible M5 thread, it’s well-suited for electronics, micro-mechanics, and precision inspection tasks. If you need a different ruby ball size, sizes beyond Ø0.2–Ø1.5 mm can be requested through the configurator or by contacting us directly.
