M3 Ø4 mm zirconia ball, tungsten carbide stem, L 40 mm, EWL 40 mm

Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible.

A tungsten carbide stem provides exceptional rigidity, particularly for styli with small ball and stem diameters. 

Zirconia is a particularly tough ceramic material with hardness and wear characteristics approaching those of ruby. Its surface properties make it an ideal material for aggressive scanning applications on cast iron components.
