Description

Precision straight stylus from ITP designed for metrology probes and CMM touchpoints. The Type B ruby-ball version with M3 XXT thread offers reliable, repeatable contact in compact measurement setups.

  • Material: Extremely rigid tungsten carbide stem for superior rigidity and wear resistance across a wide range of dimensions.
  • Tip: High-quality ruby ball tips (Ø0.3 mm to Ø1.0 mm) provide precise, repeatable contact and extended tip life.
  • Thread: M3 XXT thread ensures secure attachment to compatible probes and fixtures.
  • Overall Length: 40 mm for a compact probing reach that fits tightly constrained spaces.
  • Stem Configuration: Can be single- or multi-stepped to match your measurement strategy and reach requirements.
  • Customization: Other sizes available on request via configurator or by email to tailor to your setup.

This stylus is ideal for engineers and QA teams performing precise surface mapping, feature inspection, or edge probing. The tungsten carbide stem preserves accuracy over time, while the ruby ball tip delivers clean, repeatable contact that helps reduce measurement noise. With its robust M3 XXT interface and the option for customized dimensions, this Type B stylus integrates smoothly into a range of probing systems and fixtures, making it a dependable choice for demanding metrology tasks.
