Description
The ITP Straight Styli Type B with Ruby Ball is a precision probing accessory designed for metrology professionals who rely on repeatable, accurate measurements in daily CMM workflows. Built around a rigid tungsten carbide stem and a high-grade ruby ball, it delivers dependable contact across a range of feature sizes.
- Thread and length: M5 thread, 21.8 mm overall length for straightforward mounting in most probe heads.
- Stem material: Tungsten carbide stem provides exceptional rigidity and minimal deflection during probing.
- Tip material and sizes: Ruby ball tips available from Ø0.2 mm to Ø1.5 mm, offering precise contact for tiny features or broader tolerances.
- Configuration options: The stem can be single- or multi-stepped; other sizes can be requested via the configurator or by email.
- Catalog code: NHM500311021 for easy ordering and reference.
This stylus helps you capture precise geometric data with consistent contact, reducing measurement variation and improving data quality. The ruby ball’s hardness resists wear in demanding environments, while the tungsten carbide stem maintains accuracy over many measurement cycles. With configurable tip sizes and stepping options, it adapts to a wide range of features—from tiny holes to delicate edges—without changing tools.
