M2 stylus with 0.5 mm diameter carbide cylinder with stainless steel base, 3.0 mm diameter x 5.0 mm long. Overall stylus length is 20.0 mm. Stylus weight is 0.30 gram.

Cylinder styli are useful on thin edges, like those found on stampings and sheet metal. They are not suitable for high accuracy work because the form of a cylinder is not as precise as a sphere. Please contact Q-Mark with any questions about calibrating or using cylinder styli.
