Description
ITP Straight Styli – Type A, with a silicon nitride ball and M2 thread, is built for precise, everyday probing in CMM workflows. Its carbide stem delivers high rigidity, supporting accurate measurements on a range of parts, especially untreated aluminum.
- Thread: M2 threaded base for secure mounting on compatible probes and extensions.
- Overall length: 31 mm from base to ball, offering a compact, balanced probing point for tight spaces.
- Stem material: Carbide stem provides exceptional rigidity to minimize deflection during contact.
- Ball material: Silicon nitride ball for hardness, wear resistance, and stable performance on metal surfaces.
- Ball size range: Standard options from Ø1.0 mm to Ø5.0 mm; other sizes can be requested via the configurator or by e-mail.
- Ideal use: Particularly recommended for scanning untreated aluminum and routine measurement tasks.
The combination of a rigid carbide stem and a durable silicon nitride ball ensures repeatable, reliable measurements across multiple scans. The 31 mm length and M2 connection make it compatible with a wide range of CMM setups, while the ball-size options provide flexibility for probing different feature geometries. If your application requires a ball diameter outside the standard Ø1.0–Ø5.0 mm range, you can request a custom size through the configurator or by e-mail.
