ITP Straight Styli - Type A with a silicon nitride ball, M5 thread, and a 21 mm overall length is a precision probing stylus designed for everyday metrology work. Built for reliability and repeatable results, it suits CMM probing and scanning tasks across metal parts, including aluminum.

• Thread: M5 thread for broad compatibility with standard probing systems.
• Stem Material: Extremely rigid carbide stem to minimize deflection across a wide range of dimensions.
• Ball Material: Silicon nitride ball, chosen for wear resistance and smooth interaction with metal surfaces, especially untreated aluminum.
• Overall Length: 21 mm for compact, accessible probing in tight fixtures.
• Holder Size Options: Depending on the measuring system, styli with Ø10.0 mm, Ø11.0 mm and Ø12.0 mm holders are available in this group.
• Ball Size Range: Ball sizes from Ø1.5 mm up to Ø10.0 mm are offered within this product group.
• Customization: Other sizes can be requested via the configurator or by email.

This stylus delivers precise, repeatable contact for a wide range of measurement scenarios. The combination of a rigid carbide stem and a durable silicon nitride ball reduces wear on both the stylus and the workpiece, supporting accurate data collection during aluminum scans and other metrology tasks. Its compact 21 mm footprint and M5 connection make it a versatile choice for busy inspection workflows, where consistency across sessions matters most.
