In Stock - Despatched 1-2 Days

Quick Overview

Disc stylus with M5 thread, ruby disc Ø8 mm, tungsten carbide stem Ø2.5, length 57 mm. For use on coordinate measuring machines (CMM).

The stylus is an important part of the measuring system. During the measurement, the stylus is in direct contact with the part.
Disc styli are often used to measure recesses and grooves. Depending on the application, different materials for stems, adapters and tips are available.

Ruby is the most widely-used material for styli tips. Thanks to its inexpensive price and high quality, it is the standard choice for most applications. It is an extremely hard material, which tends, however, to cause material build-up when combined with certain materials such as aluminium.

A tungsten carbide stem has high stiffness and less thermal expansion, compared to stainless steel.
