The ITP Straight Stylus Type A with Ruby Ball is a precision probing accessory designed for metrology professionals who need reliable, repeatable touch measurements. Its rigid carbide stem and high-quality ruby ball deliver consistent contact on micro-features in CMM setups and other measurement rigs.

• Thread Mount: M4 thread at the top for secure attachment to standard probing equipment.
• Overall Length: 20.5 mm from base to ball, offering a compact, controllable probing geometry.
• Tip Material: Ruby ball tip chosen for high hardness and low wear, available in diameters from Ø1.0 mm to Ø8.0 mm.
• Stem Material: Carbide stem provides exceptional rigidity and dimensional stability under load.
• Assembly: Hand-tightened with an SW5.5 open-end spanner for quick, tool-assisted setup.
• Custom Sizes: Additional tip diameters and lengths can be requested via configurator or by e-mail to fit unique measurement needs.

Designed to minimize deflection and wear, this stylus enables repeatable measurements across multiple cycles. The standard M4 threading ensures compatibility with a wide range of probing systems, while the 20.5 mm length keeps access to tight features straightforward. The ruby ball tip provides precise contact geometry, helping reduce measurement error on delicate or micro-scale features. When your project requires different radii, simply explore configurator options or contact support to tailor the setup without sacrificing accuracy or speed.
