Description
The ITP Straight Styli Type A with Ruby Ball is a precision straight stylus designed for everyday metrology tasks. Built around a carbide stem with a high-quality ruby ball, it delivers reliable, repeatable touchpoints for standard probes and measurement fixtures.
- Thread: M5 thread for secure attachment to probe heads and holders.
- Overall Length: 58 mm from tip to the threaded end for a compact probing profile.
- Material: Carbide stem offering exceptional rigidity and long tool life under repetitive probing.
- Ruby Ball Size Range: Ruby balls available from Ø2.0 mm to Ø10.0 mm; other sizes can be requested via the configurator or by e-mail.
- Configuration: Type A straight stylus for direct, linear contact with the workpiece.
With its rigid carbide core and precisely finished ruby ball, this stylus minimizes deflection during probing, supporting higher-accuracy measurements across a range of geometries. The standard M5 connection simplifies setup with common probe heads, while multiple ruby ball sizes let you tailor the contact point to your measurement needs—whether inspecting tiny features or broader surfaces. For repeated use in production or R&D environments, the Type A straight design offers dependable, predictable performance every time you probe.
