The ITP Straight Stylus Type A with Silicon Nitride Ball is a precision probing tool designed for everyday metrology tasks. Built for reliability, it delivers steady, repeatable contact ideal for scanning and measuring parts, especially untreated aluminium.

• Ball material: Silicon nitride ball for wear resistance and smooth contact on metal surfaces.
• Stem material: Carbide stem provides exceptional rigidity and dimensional stability.
• Thread: M2 threaded connection to fit standard stylus holders and probing heads.
• Overall length: 30.75 mm, offering a compact yet stable probing reach.
• Ball size availability: Part of the Type A range; styli with balls from Ø1.0 mm to Ø5.0 mm are available, with other sizes requestable via configurator or by e-mail.
• Part number: THM2S1503031
• Ideal use: Straight stylus for everyday standard use, particularly effective for scanning parts made of untreated aluminium.

This combination of a rigid carbide stem and a durable silicon nitride ball supports consistent contact force and high measurement repeatability. The M2 thread ensures quick, secure mounting in compatible probes, while the 30.75 mm length provides a balanced, easy-to-handle profile for routine scanning tasks. The available ball-size range allows you to tailor the footprint to your part geometry, optimizing contact stability and measurement resolution for everyday metrology workflows.
