M2 stylus with 1.5 mm diameter stainless steel cylinder, 1.0 mm diameter stainless steel stem, and 3.0 mm diameter stainless steel base. Overall stylus length is 11.0 mm. Stylus weight is 0.29 gram. Compare to Zeiss 602030-8096-000. Cylinder styli are used for edge probing on stampings or sheet metal parts. They are not suitable for high accuracy work because the form of a cylinder is not as precise as a sphere. Please contact us with any questions about calibrating or using cylinder styli.
