Description
The ITP Straight Styli – Type A with a ruby ball is a precision measuring stylus designed for everyday metrology tasks. Built for reliability in probing setups, it delivers consistent contact and robust performance in standard inspection workflows.
- Thread: M5 male thread for secure mounting in compatible probes.
- Overall length: 20 mm, providing a compact, easy-to-use profile for tight workspaces.
- Stem material: Extremely rigid carbide, ensuring stiffness and dimensional stability under load.
- Ball tip diameter: Ruby ball available in sizes used for these styli, ranging from Ø1.0 mm to Ø5.0 mm for precise contact and durability.

This straight stylus is ideal for calibration checks, edge detection, and small-feature measurements in CMM and probing workflows. The combination of a carbide stem and ruby ball minimizes wear on both the stylus and the part being inspected, delivering repeatable readings across many measurement cycles. Its 20 mm length and secure M5 mounting make it a dependable choice for labs, manufacturing environments, and service technicians seeking consistent performance without unnecessary complexity.
