Description
The ITP Straight Stylus - Type S with Ruby Ball is a flexible, threadless probing solution designed for precision metrology and inspection tasks. Built for professionals who need reliable contact probes in tight spaces, it combines a durable tungsten carbide stem with a ruby ball tip for consistent measurements.
- Overall length: 16 mm
- Stem material: Tungsten carbide for rigidity and wear resistance
- Threading: Without thread, offering high flexibility and broad mounting compatibility
- Tip options: Ruby ball tip available in Ø1.35 mm to Ø10.0 mm (other sizes can be requested)
- Stem configuration: Available as single- or multi-stepped variants
- Mounting: Designed for use with the appropriate clamp holder
- Product code: KTSO01510016
This stylus delivers stable, repeatable contact across multiple measurement sessions. The tungsten carbide stem resists wear under repeated probing, while the ruby ball tip minimizes indentation and provides consistent contact on a range of materials. The threadless design enhances mounting flexibility, and the selectable ruby ball sizes let you tailor the probe’s contact area to delicate or high-contrast surfaces. Perfect for CMM probing, fixture checks, and surface profiling, it plugs into existing clamp systems for smooth, efficient workflows.
