Description

ITP Straight Styli - Type A with Ruby Ball is a precision probing stylus designed for everyday measurement tasks. Its carbide stem delivers exceptional rigidity, while the ruby ball tip ensures accurate, repeatable contact on delicate surfaces.

  • Model: Type A Straight Stylus for standard probing tasks.
  • Tip: Ruby ball tip with diameters from Ø0,5 mm to Ø6,0 mm for precise contact and durable wear resistance.
  • Stem: Carbide stem provides extreme rigidity to maintain straightness under probing forces.
  • Connection: M3 thread for secure mounting to compatible probes and measurement systems.
  • Length: 50 mm overall length, offering a balanced reach and control in tight spaces.
  • Customization: Further ruby ball sizes can be requested via the configurator or by e-mail.
  • Product Code: THM303005050

In practice, the carbide stem minimizes deflection for consistent readings across multiple cycles, while the ruby ball tip protects workpiece surfaces and provides a small, repeatable contact area for high-resolution probing. The 50 mm reach is ideal for accessing recessed features without sacrificing stability, and the standard M3 thread ensures compatibility with a wide range of probing setups. If you need a specific ruby ball size beyond the Ø0,5–Ø6,0 mm range, you can request a custom diameter through the configurator or by email to tailor the stylus to your exact measurement tasks.
