INSIZE ISQ-30-031 Ruby CMM Stylus, 2 mm Ball, 30 mm Length

INSIZE's ISQ-30-031 is a CMM stylus built around a ruby measuring ball 2 mm across, carried on a carbide rod that steps down to a 1.5 mm stem. It screws into a probe head, extension rod or multi-way base using its M3 thread. The stylus measures 30 mm overall, and INSIZE states an effective working length of 22.5 mm for this code. In use, the ball tip is what touches the part surface while the coordinate measuring machine takes each point.
