Description

The ITP Straight Styli Type A with a ruby ball is a precision measuring stylus designed for everyday probing tasks. Built for reliability and repeatable results, it’s ideal for technicians and engineers relying on accurate measurement during routine inspections and setups.

  • Thread: M5 male thread for quick, secure mounting on standard probe heads
  • Stem material: Carbide stem delivering exceptional rigidity and dimensional stability
  • Tip: High-quality ruby ball for precise contact geometry, available in Ø2.0 mm to Ø10.0 mm
  • Overall length: 50 mm, offering a balanced reach for controlled handling
  • Size options: Other ball sizes can be requested via the configurator or by email
  • Product code: THM503011050

This combination of a rigid carbide stem and a durable ruby ball minimizes deflection and wear, helping you achieve consistent readings across measurement cycles. The 50 mm length and M5 thread integrate smoothly with a wide range of probing setups, making it a dependable choice for both routine checks and detailed inspections. If you need a non-standard ball size, you can request a custom option through the configurator or by contacting support.
