In practice, this stylus delivers reliable tactile feedback with minimal inertia, helping you achieve consistent measurements across routine inspection tasks. The ceramic stem keeps the assembly light yet rigid, while the ruby ball provides a durable contact surface that resists wear over many measurement cycles. The 103 mm length strikes a balance between reach and control, making it suitable for a wide range of workholding setups and probing configurations. If you need a different ruby-ball size, you can request other diameters within the 4.0–8.0 mm range through the configurator or by email, ensuring the right contact geometry for your application.
