Description
Engineered for precision metrology, the ITP Straight Styli Type B with Ruby Ball is a straight probing stylus designed for repeatable contact in tight spaces. It’s ideal for technicians and engineers who rely on stable, accurate measurements in CMM and tactile workflows.
- Thread and Fit: M3 thread compatibility to suit standard probing heads and fixtures.
- Overall Length: 22 mm, providing compact reach for constrained measurement setups.
- Tip Material: Ruby ball tip of the highest quality, available in sizes from Ø0.2 mm to Ø1.0 mm for precise contact.
- Stem Material: Carbide stem delivering exceptional rigidity and dimensional stability under load.
- Profile: Straight (Type B) design with the option for single or multi-stepped stems to match different probing needs.
- Customization: Other ruby ball sizes can be requested via the configurator or by email to tailor the touchpoint to your application.
The carbide stem minimizes deflection during probing, enhancing repeatability across measurement cycles. Ruby ball tips provide smooth, consistent contact on rigid surfaces while extending tool life by resisting wear. At 22 mm, this stylus offers practical reach in compact fixtures, and the M3 threading simplifies integration with common probe systems. With ruby ball options from Ø0.2 mm to Ø1.0 mm, you can optimize the touchpoint for delicate features or larger details. If your application requires a different diameter, sizes can be specified through the configurator or by email to ensure you have the exact tool for your task.
