Description
ITP Star Styli - Type U with a Ruby Ball delivers stable, precise contact for challenging gauging tasks. Designed for metrology work in quality control and CMM setups, it excels at measuring large diameters, undercuts, and threaded features with dependable repeatability.
- Probe configuration: Type U star with four fixed arms provides stable contact and extended reach for difficult geometries.
- Tip material: Ruby ball tip offers durable, wear-resistant contact for consistent measurements over time.
- Thread size: M5 threaded shank for easy mounting in standard holders and fixtures.
- Measuring length: 7 mm effective measuring length to access recessed features without compromising stability.
- Versatility: Part of the Star Styli family, enabling task-specific measuring programs for a range of applications, including large-diameter bores and threaded surfaces.
The star geometry distributes contact forces across multiple fixed arms, reducing deflection and bending when measuring long gauging lengths. The ruby-tipped contact ensures wear resistance and repeatable results across measurement cycles. With a compact 7 mm reach, this Type U stylus maintains stability while accessing recessed or challenging features, making it a reliable choice for inspecting large holes, internal threads, and undercuts in precision parts. Ideal for high-precision QC workflows where consistency and efficiency matter.
