The ITP Straight Styli – Type D with Ruby Ball is a high-precision probing stylus designed for metrology, QA, and inspection workflows. Built for engineers and technicians who demand consistent, reliable contact in tight spaces, it delivers rigid performance and versatile tip options.

• Thread: M5 thread for secure, compatibility-based mounting on standard probes.
• Overall Length: 32 mm, providing compact reach suitable for cramped fixtures and accessory setups.
• Stem Material: Tungsten carbide with a stepped reinforced body for exceptional rigidity and durability across applications.
• Stem Configuration: Single or multi-stepped stem options to suit different probing envelopes and reach requirements.
• Tip Type: Ruby ball tips of the highest quality, available in diameters from Ø0,2 mm up to Ø1,0 mm for precise contact on small features.
• Custom Dimensions: Additional lengths or tip sizes can be requested via the configurator or by e-mail to match specific measurement tasks.

This stylus blends a rigid tungsten carbide stem with ultra-fine ruby ball tips to minimize deflection and wear, delivering repeatable results across multiple measurements. The small ruby spheres enable accurate contact with tiny features, making it an ideal choice for micro-scale inspection, calibration tasks, and precision probing in coordinate measuring machines (CMMs) or manual inspection setups. The ability to select single or multi-stepped stems, along with customizable tip diameters, provides the flexibility to optimize probe reach and contact geometry for your particular fixture and workflow.
