Description
The ITP Straight Styli Type A is a high-rigidity, low-weight probing stylus designed for precise CMM measurements. With a silicon nitride ball and a compact 33.5 mm reach, it excels at contacting flat, untreated aluminum surfaces in tight spaces.
- Type: Straight stylus (Type A) for direct, axial probing.
- Ball material: Silicon nitride ball provides wear resistance and smooth contact with aluminum workpieces.
- Stem material: Carbon fiber stem delivers high stiffness with minimal weight for responsive measurements.
- Thread: M5 thread compatible with standard probing interfaces.
- Overall length: 33.5 mm to extend reach into confined areas.
- Best use: Optimized for scanning untreated aluminum surfaces with clean, repeatable contact.
- Custom dimensions: Other lengths or configurations available on request via configurator or by e-mail.
Its low-mass carbon fiber stem minimizes inertia for crisp, repeatable probing, while the silicon nitride ball delivers durable, stable contact on untreated aluminum. The 33.5 mm length and M5 thread provide reliable reach and easy integration with standard probing heads, enabling access to recessed features and precise data collection across a range of measurement tasks.
