This stylus is particularly well-suited for scanning untreated aluminium parts, where the silicon nitride ball provides smooth contact and reduced wear. Its long 150 mm reach makes it easy to access features inside fixtures or recessed areas, while the carbide stem ensures rigidity across a broad range of dimensions. If you need different ball sizes beyond Ø1.5–Ø10.0 mm, they can be requested via the configurator or by email to suit specific probing tasks.
