Description
ITP Straight Styli - Type A with Ruby Ball is a precision straight stylus designed for metrology tasks that demand extended reach, minimal deflection, and repeatable results. Built for engineers and technicians, it combines a lightweight carbon fiber stem with a high‑quality ruby ball for reliable, long‑lasting contact.
- Part code: TCM503010051
- Thread: M5 to fit standard probes and holders
- Overall length: 51.5 mm, providing extended reach in constrained spaces
- Stem material: Carbon fiber for exceptionally low weight and high rigidity
- Tip: Ruby ball available in multiple diameters (Ø3.0 mm to Ø12.0 mm) for precise contact on various features
- Construction: Straight geometry to minimize lateral forces and maximize stability during probing
- Customization: Other dimensions can be requested via the configurator or by email
This stylus is ideal for CNC inspection, coordinate measuring, and manual probing where long reach and stable contact matter most. The carbon fiber stem reduces load on the probing system, while the ruby ball tip delivers durable, smooth engagement with minimal wear over many measurement cycles. If your application requires a different ruby ball size or non‑standard dimensions, you can tailor the stylus through the configurator or by contacting the supplier for a precise fit.
