Description
ITP Straight Stylus, Type A with a Ruby Ball tip, is a rigid carbide-stem probe designed for reliable, everyday tactile metrology. This model (THM202503041) pairs a durable carbide shaft with a high-quality ruby ball for consistent contact in standard probing workflows.
- Tip Type: Ruby ball tip offers hard, wear-resistant contact with minimal marring on delicate surfaces. Available in sizes from Ø0.5 mm to Ø5.0 mm, with custom sizes configurable by the configurator or by email.
- Stem Material: Carbide stem delivers exceptional rigidity and long tool life, maintaining dimensional accuracy through extended use.
- Thread Compatibility: M2 threaded connection for secure attachment to compatible probes and holders.
- Overall Length: 41.25 mm, a compact, versatile length suitable for crowded fixtures and tight measurement pockets.
- Design Type: Type A configuration optimized for standard, reliable probing performance across everyday tasks.
This stylus is designed to deliver repeatable measurements with minimal deflection, making it suitable for CMM touch probes, micro-machining inspection, and precision assembly checks. The ruby-ball options let you tailor the tip footprint to feature size, reducing measurement time and avoiding tip overload in diverse workholding scenarios. If you need a size outside the standard range, you can request additional ruby-ball diameters through the configurator or by email, ensuring you have the right tip for your application.
