The ITP Straight Styli Type A with a ruby ball is a precision probing stylus designed for reliable, everyday metrology tasks. Built around a rigid carbide stem, it delivers consistent contact and durable performance in quality control and engineering environments.

• Model / Part Number: THM202003016
• Material: Carbide stem for exceptional rigidity and wear resistance
• Thread: M2 thread for secure mounting in standard probe fixtures
• Overall Length: 16 mm total length for compact access in tight spaces
• Ball End: Ruby ball available from Ø0.5 mm to Ø5.0 mm with high-quality, durable surface
• Customization: Further ruby ball sizes can be requested via the configurator or by e-mail

Designed for reliability in precision measurements, the straight form offers predictable contact geometry that supports repeatable data across CMM probing, 3D scanning, and fixture alignment. The carbide stem resists wear even after many probing cycles, helping maintain accuracy over time. The ruby ball provides a hard, smooth contact surface that minimizes surface damage and yields consistent measurements. Its compact 16 mm length and robust M2 mounting integrate smoothly with compact measurement heads and automated setups. For projects requiring different ruby ball diameters, sizes from 0.5 mm to 5.0 mm are available, with additional sizes obtainable through the configurator or by email.
