Description
The ITP Straight Styli Type A with a diamond-coated ball is a high-precision probing solution built for demanding metrology tasks. Designed for professionals who require repeatable, accurate contact in tight or recessed spaces, this stylus delivers dependable performance across long measurement sessions.
- Thread: M5 external thread for secure, compatible attachment to standard probe interfaces.
- Overall Length: 64 mm, providing extended reach for challenging features and tall fixtures.
- Stem Material: Extremely rigid carbide for minimal deflection and superior accuracy under load.
- Ball Material: Diamond-coated silicon carbide (SiC) ball for exceptional wear resistance and long service life.
- Ball Size Range: Probes in this group cover Ø1.5 mm to Ø10.0 mm balls; other sizes can be requested via the configurator or by email.
- Design: Straight stylus optimized for stable contact and consistent measurements in varied geometries.
This combination of a hard carbide stem and a diamond-coated SiC ball translates to durable performance with reduced downtime. The diamond coating minimizes wear on the contact surface, helping maintain measurement integrity across thousands of cycles, while the rigid stem keeps deflection to a minimum for repeatable results. The 64 mm length and standard M5 connection ensure compatibility with common probing setups, making it a reliable choice for production metrology, fixture-based inspection, and quality-control workflows. If you need a different ball diameter for a specific feature, sizes outside the listed range can be arranged through the configurator or by contacting us for a custom option.
