• Overall length: 23 mm for compact reach and stable probing
• Stem material: Carbide for extreme rigidity and minimal deflection
• Ball material: Ruby ball renowned for hardness and wear resistance
• Ball sizes: Available from Ø1.0 mm to Ø6.0 mm to suit feature size
• Design: Straight stylus optimized for everyday, standard-use probing
• Custom sizes: Other sizes can be requested via the configurator or by e-mail

Designed for metrology professionals and workshop technicians, this straight stylus provides predictable probing behavior and long wear life. The carbide stem minimizes bending under typical probe loads, while the ruby ball maintains a sharp, durable contact surface across numerous measurements. With multiple ruby ball diameters available, you can tailor the stylus to small features or larger land areas, improving feature detection and measurement speed. The 23 mm length and M4 threading ensure quick integration with existing probe systems and fixtures, reducing setup time and boosting throughput. If you need a size outside the standard Ø1.0–Ø6.0 mm range, request it through the configurator or by email.
