M2 Ø4mm Zirconia ball styli, carbon fiber stem, L 100 mm, EWL 100 mm
Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible. A Carbon Fiber stem is very lightweight and ideal for applications where weight is critical. Zirconia is a 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.
