Description
ITP Straight Styli – Type A with a ruby ball tip offers lightweight, ultra-rigid probing performance for precision measurement tasks. Designed for long-reach needs, this M5-threaded stylus blends a carbon fiber stem with a high-quality ruby ball to deliver dependable, repeatable results.
- Overall length: 304 mm
- Stem material: Carbon fiber for high rigidity and low weight
- Ruby ball tip: High-quality ruby contact balls available in Ø3.0 mm to Ø12.0 mm
- Thread: M5 threading for secure mounting on compatible probes

The carbon fiber stem minimizes deflection during probing, helping maintain accuracy even when reaching into deep features. The ruby ball tip provides durable, low-friction contact that reduces wear on both the stylus and the workpiece, ensuring stable, repeatable readings over many cycles. With a long 304 mm reach and a robust M5 connection, this stylus is well-suited for CMM applications, intricate grooves, or pockets where precision and reliability are essential. If you need a different diameter or length, you can request other dimensions to tailor the tool to your setup.
