The ITP Straight Styli Type S with Ruby Ball is a precision, threadless stylus designed for flexible probing in metrology setups. Built for technicians and engineers using clamp-based measurement systems, it delivers reliable contact with a durable, long-lasting tip.
- Design: Straight (Type S) geometry for direct probing paths in tight or awkward spaces
- No-thread design: Threadless interface that reduces binding and increases Flex when navigating challenging features
- Tungsten carbide stem: Highly rigid, wear-resistant shaft that supports either single- or multi-stepped configurations
- Ruby ball tips: Available in sizes from Ø1.35 mm to Ø10.0 mm; other sizes can be requested via the configurator or by e-mail
- Clamp-holder compatibility: Designed to work with the appropriate clamp holder for secure, stable mounting
- Overall length: 26.5 mm, ideal for compact fixtures and tight measurement setups
- Product Code: KTM501510026
This ruby-ball stylus minimizes wear on both the tip and the workpiece while delivering repeatable contact across repeated scans. The non-threaded design reduces interference in constrained fixtures, and the tungsten carbide stem maintains high accuracy under demanding conditions. Choose the ruby-ball size that matches your feature geometry, and request additional sizes if needed through the configurator or by e-mail.
