Description

The ITP Straight Styli – Type B with Ruby Ball is a precision probing solution built for meticulous measurement tasks. Designed for metrology professionals, QA labs, and toolmakers, it delivers reliable contact and consistent results in CMM and handheld inspection workflows. Model THM500310030 features a 30.15 mm overall length with a secure M5 thread.

  • Ball tip options: High-quality ruby balls available from Ø0.2 mm to Ø1.5 mm for precise contact and repeatable measurements.
  • Stem material: Extremely rigid tungsten carbide stem to resist deflection and wear during probing.
  • Geometry: Straight stylus design suitable for direct contact; available as single- or multi-stepped stems to fit measurement setups.
  • Thread compatibility: M5 thread ensures secure mounting on compatible probes and fixtures.
  • Overall length: 30.15 mm compact profile that balances reach with stability in tight measurement areas.
  • Customization: Other tip sizes and configurations can be requested via configurator or by email to tailor the stylus to specific parts and applications.

This stylus combines the durability of a tungsten carbide shaft with the precision of premium ruby ball tips, delivering stable contact and long-term accuracy across a range of materials and feature sizes. The Type B straight form factor simplifies alignment with small features, while the ability to specify alternate tip diameters makes it adaptable to micro-scale inspection or delicate components. For engineers and technicians seeking a dependable, ready-to-use probing solution that pairs well with existing measurement setups, this ITP straight stylus offers consistent performance and easy integration.
