Description
The ITP Straight Stylus Type A with a silicon nitride ball and M5 thread is a precision probing accessory designed for reliable, everyday measurement tasks in CMM and metrology workflows. Built for durability and consistent data, it’s ideal for engineers and technicians who need stable, repeatable contact in tight spaces.
- Thread: M5 mount for secure, quick attachment to standard probing systems.
- Overall Length: 50 mm, providing a compact reach for recessed features and confined fixtures.
- Stem Material: Carbide stem delivers exceptional rigidity, minimizing deflection under load.
- Ball Material: Silicon nitride ball chosen for wear resistance and smooth interaction with scanned surfaces, especially untreated aluminium.
- Ball Size Range: part of a line offering ball diameters from Ø1.5 mm to Ø10.0 mm; other sizes can be requested via configurator or by email.
- Holder Compatibility: compatible with standard holder sizes in this family (Ø10.0 mm, Ø11.0 mm, Ø12.0 mm) for flexible setup options.
This stylus delivers repeatable contact points and clean data across a variety of parts and fixtures. The combination of a rigid carbide stem and a silicon nitride ball reduces deflection and wear, enabling accurate measurements on a wide range of materials, with particular effectiveness on untreated aluminium. Ideal for routine inspection, calibration checks, and precision probing where stable performance matters.
