The ITP Straight Styli - Type T with Ruby Ball is a threadless (no-thread) probing stylus designed for precision metrology in tight spaces. Its tungsten carbide stem and ruby ball tip deliver reliable, repeatable contact for CMM probing and other measurement tasks, with a compact 22.5 mm overall length.
- Threadless design: No threading, enabling maximum flexibility and straightforward mounting with the appropriate clamp holder.
- Ruby ball tip: Available in sizes from Ø0.2 mm to Ø5.0 mm to suit different surface profiles and contact requirements.
- Tungsten carbide stem: High-hardness, wear-resistant shaft that can be configured as single or multi-stepped to match probing needs.
- Compact length: 22.5 mm overall length provides access to confined measurement points.
- Clamp-holder compatibility: Designed for seamless use with the corresponding clamp holders for secure, repeatable performance.
This stylus is ideal for technicians and engineers who require precise, durable probing in compact fixtures. The ruby ball’s hardness and consistent geometry help minimize measurement variance across scans, while the threadless design reduces setup time and increases positioning flexibility. If you need a specific ruby ball diameter beyond Ø0.2–Ø5.0 mm, sizes can be requested via the configurator or by email.
