The ITP Straight Styli Type J with a silicon nitride ball is a low-weight, high-rigidity stylus designed for precise probing in demanding metrology tasks. It’s built for users needing a long-reach solution that maintains accuracy on challenging surfaces, such as untreated aluminium.

• Model: Straight stylus, Type J, optimized for stable performance with a carbon fiber stem
• Ball Material: Silicon nitride ball for durable, smooth contact on metallic workpieces
• Thread: M3 connection for secure attachment to compatible probe heads
• Length: 104 mm overall length to reach recessed features while minimizing deflection
• Stem: Carbon fiber stem, chosen for excellent stiffness-to-weight ratio
• Part Number: TCM3S8004104
• Customization: Other dimensions available via configurator or by email

This stylus delivers stable, repeatable measurements by combining a light, rigid carbon fiber body with a durable silicon nitride ball. The long reach is ideal for probing inside tight cavities or accessing features that are difficult to reach with shorter styluses, while the M3 thread ensures straightforward compatibility with standard probing systems. If you’re working with aluminium or similar metals, this Type J design helps minimize measurement noise and wear, supporting consistent results across batches and sessions.
