Description
ITP Star Styli with Ruby Ball is a precision CMM probe accessory designed for metrology professionals who need to measure large diameters, undercuts, and threaded features with long gauging lengths. Built for reliability and repeatability, this star-style stylus handles extended reach without bending and supports task‑specific measurement programs.
- Tip: Ruby ball tip for accurate, repeatable contact measurements at challenging radii and depths.
- Thread: M3 XXT thread for quick, secure compatibility with standard probe heads.
- Measuring length: 21 mm measuring length, enabling deep measurements without compromising stability.
- Design: Star-style with multiple fixed probe arms to configure task‑specific measurement setups and reduce probe bending over long gauging lengths.
- Applications: Ideal for measuring large diameters, undercuts, and threaded features; when no probe is in the stem direction (type W), measurements can reach close to the bottom of the hole.
- Part number: SCM303005030
This stylus delivers practical, field‑tested benefits: you gain dependable measurements on difficult geometries, consistent probe behavior across repeated runs, and flexible programming options that adapt to diverse inspection tasks. The ruby ball finish provides clear contact and durable wear resistance, helping you maintain accuracy over time without frequent probe changes.
