M3 Ø4 mm zirconia ball, ceramic stem, L 50 mm, EWL 46 mm

Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible. A ceramic stem is lightweight yet very stiff and offers built-in crash protection.

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.
