Description
Engineered for precision metrology, the ITP Straight Styli Type A with a ruby ball delivers a lightweight, high-rigidity probing solution for long‑reach CMM tasks. Designed for technicians who demand repeatable, accurate contact in challenging fixtures, this model is built to perform.
- Thread: M5 male thread for secure mounting on standard probing systems.
- Overall Length: 79 mm reach to access hard‑to‑reach features without sacrificing rigidity.
- Stem Material: Carbon fiber core offering an excellent strength‑to‑weight ratio and stiffness.
- Tip: Ruby ball tip for durable, wear‑resistant contact with smooth, repeatable readings. Diameters range from Ø3.0 mm to Ø12.0 mm across these styli.
- Customization: Other dimensions can be requested via the configurator or by email to tailor the stylus to your setup.
This straight stylus combines a featherweight carbon fiber stem with a precisely manufactured ruby ball to minimize deflection during probing, which translates to improved measurement repeatability. The long reach is ideal for inspecting features tucked into recesses or extending across fixtures, while the ruby ball delivers consistent contact performance over many cycles. The M5 connection keeps your probing system secure, and flexible dimension options let you align the stylus with specific fixture geometries without compromising performance.
