Description
The ITP Straight Styli – Type E with Ruby Ball delivers precise, reliable probing performance for metrology professionals. Built for high-accuracy measurements in CMM and manual inspection workflows, it combines a rigid tungsten carbide stem with a premium ruby ball for consistent contact and minimal wear.
- Thread: M5 male thread at the top for secure attachment to probing heads and accessories.
- Overall Length: 55 mm, a compact yet robust profile that preserves stability during probing.
- Reinforced Body: Long, reinforced design to minimize flex and enhance measurement repeatability.
- Stem Material: Tungsten carbide stem provides exceptional rigidity and dimensional stability under use.
- Ruby Ball Tip: High-quality ruby ball for smooth contact and low wear, available in sizes from Ø 1.0 mm to Ø 3.5 mm.
- Custom Dimensions: Other dimensions can be requested via the configurator or by email to tailor the probe to specific tasks.
- Part Number: FTM502011055, Type E configuration designed for precision metrology applications.
This straight stylus is ideal for high-precision surface measurements, feature probing, and geometric tolerance checks where consistent tip geometry and stiffness are critical. The tungsten carbide core resists deflection, helping you achieve repeatable readings across sessions, while the ruby ball tip provides a reliable, low-friction contact with workpieces. Use it for detailed inspections in aerospace, automotive, tooling, and manufacturing environments where tight tolerances matter. If you need a different ruby ball diameter or a unique length, you can request a custom option to fit your specific measurement scenario.
