These features translate into tangible benefits: the carbide stem minimizes bending or deflection during probing, enhancing measurement accuracy and repeatability. The ruby ball is a hard, wear-resistant contact that maintains a precise, smooth touch on workpieces, reducing surface damage. The longer contact surface helps stabilize readings on challenging geometries, while the M5 thread and compact 63.5 mm length support quick, secure setup in busy inspection workflows. Ideal for engineers and technicians who rely on consistent, high-quality data for quality control, calibration, and process verification.
