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.

M2 Ø6 mm ruby disc, 1.2 mm width, with roller

Disc styli are designed to inspect undercuts and grooves within bores which may be inaccessible to star styli. A range of disc styli offers a radius end roller to enable groove width measurement. Ruby is regarded as the industry standard for stylus tips. It is one of the hardest materials available and suitable for most applications. Due to adhesive pickup, ruby tips are not recommended for scanning aluminum parts.
