Description

The ITP Straight Styli Type A with Ruby Ball is a precision probing stylus built for metrology tasks that require dependable, repeatable contact measurements. With a carbide stem for exceptional rigidity, a high-quality ruby ball, a 64 mm overall length, and an M5 thread, this stylus offers reliable performance for everyday standard use (SKU THM504011064).

  • Material: Carbide stem delivering extreme rigidity and long-term wear resistance.
  • Ruby ball sizes: Available in ruby balls from Ø2.0 mm to Ø10.0 mm for precise contact geometry.
  • Overall length: 64 mm to reach recessed features while maintaining control.
  • Thread: M5 thread at the top for secure mounting with standard probes and fixtures.
  • Customization: Other ball sizes available on request via configurator or email.

This straight stylus supports consistent touchpoints and reduces measurement variability by combining a rigid carbide stem with a wear-resistant ruby contact ball. The ruby ball’s durability helps maintain precise geometry through repeated cycles, while the 64 mm length expands your reach to access features beyond flat surfaces. With a reliable M5 connection, it pairs smoothly with common probe systems and fixtures, making it a dependable choice for routine calibration, QA checks, and dimensional inspection tasks.
