Engineered for repeatability, this stylus minimizes measurement uncertainty thanks to its rigid carbide stem and precisely formed silicon nitride ball. The 20 mm length and M5 thread offer a compact yet secure solution for accessing tight features, edges, and shallow pockets. The silicon nitride ball is particularly advantageous when probing untreated aluminum, delivering cleaner contacts and reducing wear. With options for single or multi-stepped stems, you can tailor the probe geometry to your part shape and measurement strategy. If your application requires a different diameter or length, you can request sizes beyond the standard range through the configurator or by email, making this stylus a dependable, everyday choice for metrology teams seeking accuracy and versatility.
