- Thread: M4 threaded shank for quick, secure attachment to common probing heads.
- Overall length: 20 mm to suit compact setups and precise reach in tight inspection zones.
- Ball material: Silicon nitride ball for hardness and smooth contact on aluminum surfaces.
- Stem material: Stainless steel offers high rigidity and durable performance.
- Ball size options: Available with balls from Ø1.0 mm to Ø8.0 mm; custom diameters can be requested via configurator or by email.
- Design: Straight stylus optimized for everyday standard use in metrology and probing tasks.
This stylus provides stable, repeatable contact data across routine measurements. The robust stainless steel stem minimizes deflection for consistent readings, while the silicon nitride ball handles wear and provides reliable engagement with untreated aluminum workpieces. With its compact form and adaptable ball sizes, it’s a practical choice for teams seeking dependable performance without premium pricing. If you need a diameter outside the standard Ø1.0–Ø8.0 mm range, you can request a custom size through the configurator or by email, ensuring the right fit for your inspection workflow.
