Description
ITP Straight Styli Type A with a ceramic ball delivers precise, reliable probing for everyday metrology tasks. Designed for technicians, engineers, and quality labs, it combines a rigid carbide stem with a wear‑resistant ceramic contact ball to ensure consistent measurements across a wide range of dimensions.
- Overall Length: 118 mm from end of ball to the threaded connection for stable reach in tight spaces.
- Thread: M5 thread compatible with standard probe holders and fixtures.
- Stem Material: Carbide for exceptional rigidity and minimal deflection during probing.
- Ball Material: Ceramic (Al2O3) for durable, smooth contact with workpieces.
- Ball Size Options: Available in Ø12.0 mm to Ø15.0 mm to suit different feature geometries.
- Product Type: Type A straight stylus, optimized for straightforward alignment and measurement tasks.
- Customization: Other sizes can be requested via the configurator or by e‑mail for specific applications.
This stylus is ideal for CNC metrology, coordinate measuring machine (CMM) setups, and inspection workflows where repeatable contact geometry and minimal wear are essential. The combination of a rigid carbide stem and a ceramic contact surface helps maintain accuracy over many cycles, even when probing varied materials or small features. With its standard 118 mm length and M5 interface, it integrates smoothly into existing probing rigs, making it a dependable choice for routine checks or precise feature verification. If your application requires a different contact diameter, exact size options are available on request to match your measurement strategy.
