M2 Economical STAINLESS Stem Styli 1.0 – 8.0 mm Ball

Highly Spherical Ball Styli are the most common tips for use on CMMs with touch trigger probe systems. The sphericity of the ball and stiffness of the stem are critical for getting the most accurate measurements The stylus is calibrated for exact diameter and then software compensation creates the measured point at the ball center instead of the surface in contact with the part.

The styli below are the only ones offered with a Stainless Steel stem. They are the lowest cost stylus and are limited to 1mm ball to 8mm ball and maximum length of 25mm.

Ruby is the most common, very spherical, physically hard and durable ball material. Specialized materials like Silicon Nitride, Zirconia and even Diamond are used for specific materials measurement especially when physically scanning the material surface rather than taking discreet points.
