Description
The ITP Straight Styli Type A with Ruby Ball combines ultralight clarity with maximum rigidity for precision probing in metrology. Built for long-reach applications, it keeps mass low while delivering dependable stiffness for accurate measurements.
- Thread: M5 external thread compatible with standard probe heads for quick, secure mounting.
- Overall length: 22 mm total length designed for compact yet capable reach in tight measurement spaces.
- Stem material: Carbon fiber stem delivering high rigidity with minimal weight for exceptional dynamic response.
- Ruby ball diameters: High-quality ruby balls available from Ø3.0 mm to Ø12.0 mm to suit different probing tasks.
- Long-reach design: Optimized for styli with extended length while maintaining structural integrity and repeatable contact.
- Customization: Other dimensions can be requested via the configurator or by email to fit unique setups.
This stylus is ideal for coordinate measuring machines and tactile metrology where a light touch and stiff performance matter. The carbon fiber construction minimizes deflection during rapid sweeps, while the ruby ball provides hard, wear-resistant contact for many measurement cycles. Whether you’re inspecting fine features, deep pockets, or complex geometries, this Type A stylus offers reliable, repeatable performance with flexible sizing options to match your workflow.
