Product description:

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. 

Ruby is regarded as the industry standard for stylus tips. It is one of the hardest materials available and suitable for most applications. 

Ruby provides a long life without wearing of the surface from abrasive materials.
