Description
ITP Straight Styli Type A with a silicon nitride ball and M5 thread offers a reliable, everyday solution for precision measurement tasks. Designed for CMMs and handheld scanners, its rigid carbide stem and durable ball deliver consistent performance on aluminum parts and in tight spaces.
- Thread: M5 male thread for secure, quick mounting into compatible probes.
- Overall length: 64 mm reach to access recessed features and hard-to-reach areas.
- Stem material: Extremely rigid carbide for stable, repeatable measurements.
- Ball material: Silicon nitride ball provides durability and smooth contact, especially on aluminum surfaces.
- Ball size range in the family: This product group includes styli with ball sizes from Ø1.5 mm to Ø10.0 mm; other sizes can be requested via the configurator or by e-mail.
- Ideal use: Straight stylus designed for everyday standard measurement tasks and scanning applications.
Designed for dependable, repeatable measurements, this stylus delivers consistent contact geometry at every touch. The 64 mm length provides extended reach for features behind openings or inside pockets, while the carbide stem resists deflection under probing loads. The silicon nitride ball enhances wear resistance and performs well when scanning untreated aluminum parts, helping maintain accuracy over time. Ideal for routine inspections, aluminum part scanning, and general CMM workflows, it pairs with standard probing setups to deliver reliable results with minimal maintenance. If you need different ball sizes or a longer/shorter reach, you can explore options in the configurator or contact support for a tailored solution.
