The ITP Straight Stylus Type A is a precision probing stylus designed for everyday measurement tasks in CMM setups. It pairs a high‑performance ceramic stem with a silicon nitride ball to deliver light, rigid, and repeatable contact on metal surfaces, including untreated aluminium.

• Thread size: M5 male thread for secure mounting in probing systems.
• Overall length: 54 mm from base to ball for a compact reach in tight features.
• Ball material: Silicon nitride ball offers high hardness, wear resistance, and smooth contact.
• Stem material: High‑performance ceramic stem provides light weight and rigidity to minimize deflection.
• Surface compatibility: Optimized for scanning untreated aluminium workpieces to reduce marring and improve data quality.
• Size options within the family: Ball sizes in this product group range from Ø5.0 mm to Ø10.0 mm; other sizes can be requested via configurator or by email.

Using the Type A stylus helps you achieve consistent, accurate coordinate data across features, edges, and holes while preserving surface finish on aluminium components. The slim 54 mm profile and rigid ceramic stem keep readings stable even in confined spaces, reducing rework and boosting inspection throughput. With its robust silicon nitride ball, this stylus stands up to repeated probing cycles, delivering reliable performance across many measuring sessions.
