Description
The ITP Straight Styli Type A with a ruby ball is a precision probing stylus built for everyday metrology tasks. Its carbide stem delivers exceptional rigidity to preserve measurement accuracy when used with standard M4-thread probing systems.
- Product type: Type A straight stylus designed for reliable, everyday measuring tasks.
- Tip material: High-quality ruby ball for precise, repeatable contact on diverse surfaces.
- Tip size range: Ruby ball diameters available from Ø1.0 mm to Ø6.0 mm.
- Stem material: Carbide stem providing superior rigidity and dimensional stability.
- Thread compatibility: M4 threaded interface for wide compatibility with common probe assemblies.
- Overall length: 53 mm overall length for balanced handling and reach.
- Custom sizes: Additional sizes can be requested via the configurator or by e-mail.
The ruby ball tip ensures minimal deflection and consistent contact pressure, helping you capture high-quality data on complex geometries. The 53 mm length offers a comfortable reach for standard probing setups, while the carbide stem’s rigidity reduces bending or flex during measurement cycles. This makes the stylus well-suited for routine dimensional checks, feature verification, and quick-inspection tasks across a range of materials and surface finishes.
