M2 Ø6 mm silicon nitride ball, stainless steel stem, L 10 mm, EWL 10 mm

Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible. A stainless steel stem offers excellent rigidity and is ideal for applications where weight is not critical. Silicon nitride is a very hard and wear resistant ceramic which can be machined into very high precision spheres. It does not have the attraction to aluminium and so does not exhibit the adhesive wear seen with ruby in similar applications.
