Styli with M3 XXT thread were developed especially for ZEISS VAST XXT measuring probes. ZEISS M3 XXT styli have a much higher rigidity than conventional M3 styli. This stiffness is achieved through a 1 mm larger diameter of the XXT adapter with a titanium allow base body. This alloy also makes the adapters significantly lighter than steel, non-magnetic and corrosion resistant. In the M3XXT range, different stylus elements (sphere, ball cylinder etc.) made of different materials and different shaft designs (shape, material) are available.
Styli with straight shaft are used for all standard applications.
Styli with stepped shaft for easy accessible parts requiring small spheres.
L-styli are particularly suitable for measuring undercuts in bores.
T-styli are particularly suitable for measuring opposing undercuts, such as grooves.
Star styli enable measurements in different coordinate directions.
Cylinder styli measure two-dimensionally and are used to measure thin sheets narrow workpiece edges.
