Description
The ITP Straight Styli - Type A with a ruby contact ball is a precision touch stylus designed for metrology professionals and everyday measurement tasks. Its rigid carbide stem and high-quality ruby ball deliver repeatable, accurate touch readings in tight fixtures and on delicate surfaces.
- Thread: M4 thread on the stylus shank for easy integration with standard probing systems.
- Overall length: 24 mm, offering a compact reach for confined measurement zones.
- Stem material: Carbide for exceptional rigidity and long-term stability under repeated use.
- Tip material: Ruby ball providing a wear-resistant, spherical contact surface for precise measurements.
- Installation: Hand-tightened with an SW5,5 open-end spanner for secure, tool-assisted fitting.
- Custom sizing: Other sizes are available via the configurator or by e-mail to match specific measurement needs.
With its combination of a stiff carbide stem and a durable ruby ball, this stylus minimizes deflection and wear, ensuring consistent contact force and repeatable readings across measurement sessions. The 24 mm length and M4 threading streamline integration into existing CMM setups, while optional sizes let you tailor the stylus to particular parts, fixtures, or delicate surfaces. Ideal for tactile probing in coordinate measuring machines, inspection workflows, and quality control processes where precision truly matters.
