This straight stylus is built to minimize deflection under load, helping you maintain accuracy across a wide range of feature sizes. The high-quality ruby ball offers a hard, smooth contact surface that resists wear, extending the stylus life and reducing workpiece wear during repeated probing. The combination of a carbide stem and ruby ball enables precise measurements from tiny pits and sharp corners to flat faces, making it a versatile choice for everyday metrology workflows. The standard M3 mounting thread ensures easy integration with common probing heads, while the 42.5 mm length suits compact fixtures and accessible features. If your measurement tasks require a different ruby-ball diameter, you can order additional sizes through the configurator or by email to tailor the stylus to your specific use cases.
