This stylus is built to improve measurement reliability in everyday use. The rigid carbide stem minimizes bending during contact, producing consistent readings across multiple workpieces. Ruby balls offer hard-wearing, low-friction contact with surfaces, reducing wear on both the stylus and the part. The 31.5 mm length provides a versatile reach for a wide range of fixtures, while the M5 mounting ensures compatibility with common probing systems. If you need a different ball diameter, you can specify a custom size via the configurator or by email, keeping your setup aligned with your exact inspection plan.
