The combination of a carbide stem and a ruby ball delivers reliable performance across daily metrology tasks. The rigid stem minimizes deflection during contact, helping you achieve repeatable readings on various surfaces, including hard or reflective materials. The ruby ball offers a durable, low-wear contact surface that helps extend stylus life while maintaining measurement accuracy. With a 20.35 mm length and M2 threading, this stylus integrates smoothly into compact measurement setups, and the option to choose different ruby ball sizes provides the right contact geometry for tiny features or delicate edges.
