Renishaw, M4 Ø6 mm ruby ball, carbon fibre stem, L 150 mm, EWL 138.5 mm, A-5003-6511

Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible. A carbon fibre stem is very lightweight and ideal for applications where weight is critical. 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 aluminium parts.
