ITP Straight Styli Type A with a silicon nitride ball provides a reliable probing accessory for CMM users who need precise, repeatable measurements on a range of parts. This 41 mm overall length stylus features an M3 thread for quick mounting on standard probe heads.
- Ball material: Silicon nitride ball for smooth contact, reduced wear, and reliable data when probing aluminum and other common materials.
- Stem construction: Carbide stem delivers rigidity and dimensional stability across a wide range of dimensions.
- Thread and length: M3 threaded interface with 41 mm overall length for compatibility with a broad set of probing systems.
- Ball size range: Ball diameters from Ø1.5 mm up to Ø5.0 mm are supported within this product range.
- Custom dimensions: Additional dimensions can be requested via the configurator or by email to fit unique inspection scenarios.
- Best-use scenario: Particularly effective for scanning untreated aluminum surfaces, where SiN balls minimize adhesive buildup and wear on the tip.
Note: Silicon nitride balls are favored for aluminum work due to reduced sticking and wear, helping maintain accuracy over longer measurement campaigns.
With its rigid carbide stem and silicon nitride ball, this stylus delivers stable points and repeatable measurements at the tip, even in challenging feature geometries. The 41 mm length positions the ball for optimal contact on tight features, while the M3 thread ensures straightforward mounting on compatible probing heads. Ideal for routine inspection of housings, fixtures, and machined parts, it supports precise data collection with fewer re-measurements. For tweaks to ball size or other dimensions, use the configurator or email to request Ø1.5–Ø5.0 mm options and other custom lengths.
