Description
The ITP Straight Styli – Type A, featuring a silicon nitride ball, is a precision probing stylus designed for reliable everyday metrology. Built for professionals who demand consistent contact and long-term stability, it pairs a rigid carbide stem with a high-performance ball for accurate measurements in tight inspection environments.
- Thread: M5 thread for secure attachment to compatible probes and CMM systems.
- Overall length: 33.5 mm, offering a compact, versatile reach for diverse workpiece geometries.
- Stem material: Ultra-rigid carbide stem to minimize deflection and maintain dimensional accuracy.
- Ball material: Silicon nitride ball chosen for durability and reliable performance on untreated aluminium surfaces.
- Configuration: Straight stylus designed for standard probing tasks and repeatable data collection.
- Product designation: NHM5S2011033
This stylus excels in scenarios that require stable, repeatable contact with a variety of part geometries. The silicon nitride ball reduces wear and galling when scanning aluminum workpieces, helping preserve surface integrity over many measurement cycles. Ideal for quality control labs, manufacturing floors, and precision inspection environments, it supports accurate data capture with consistent tactile feedback. If you need different ball sizes, other options in this product family can be requested via the configurator or by email.
