Description
Introducing the ITP Star Stylus - Type V, Ruby Ball, M5 Thread x 4 mm Measuring Length. This precision star stylus is designed for metrology applications where large diameters, undercuts, and threads demand high rigidity and repeatable contact.
- Type: Type V star stylus with fixed probe arms for task-specific measuring programs
- Thread: M5 connection for direct integration with CMM probes and star configurations
- Measuring length: 4.0 mm measuring length (ML)
- Contact ball: Ruby ball tip for wear resistance and consistent readings
- Materials: Carbide stem for rigidity; stainless steel base for durability
- Overall length: 40.0 mm total length
- Ball diameter: 1.8 mm contact ball
- Ideal use: Measuring large bores, undercuts, and threaded features with reduced bending risk
This star stylus delivers stable, repeatable measurements even along long gauging lengths where bending would compromise accuracy. The ruby ball provides reliable contact wear resistance for thousands of cycles, while the carbide stem and stainless base resist wear in tough inspection environments. Its fixed-arm Type V configuration makes it straightforward to build task-specific measuring programs, and the M5 thread ensures quick, secure integration with standard probe systems. Use it to check bore diameters, shoulders, internal threads, or undercuts, with confidence that results will be consistent across parts and setups.
