Meet the ITP Straight Styli Type A with Ruby Ball—an ultra-rigid, M5-threaded stylus crafted for reliable, everyday probing in metrology and manufacturing settings. Designed for technicians and engineers who demand consistent contact and long-lasting durability in CMM and machine-tool environments.

• Design: Straight stylus geometry for predictable contact in probing routines
• Material: Carbide stem delivering exceptional rigidity and minimal deflection
• Tip: Ruby ball provides hard, wear-resistant, smooth contact with workpieces
• Ball Size Range: Available ruby balls from Ø1.5 mm to Ø8.0 mm; other sizes can be requested via configurator or by email
• Thread: M5 thread for secure, compatible mounting with standard probe systems
• Overall Length: 57 mm, offering practical reach for a wide range of features

Employing a carbide stem and ruby ball, this stylus minimizes deflection and measurement variability, helping you achieve repeatable touches and longer stylus life. The compact 57 mm length provides access to recessed features without sacrificing rigidity, while the M5 mounting ensures broad compatibility with common probing setups. If your application requires a different ruby-ball size, you can tailor the stylus to your needs via the configurator or by email, ensuring you have the right contact geometry for tiny features or larger pockets.
