The ITP Straight Styli Type A with a silicon nitride ball is a precision probe stylus designed for everyday measurement tasks, delivering reliable contact and repeatable data for CMM scanning on metal parts, including untreated aluminium.

• Ball material: Silicon nitride ball for exceptional hardness, wear resistance, and stable contact on challenging metal surfaces.
• Stem material: High-performance ceramic stem that is light and rigid, minimizing deflection during probing.
• Thread size: M5 threaded shank for quick, secure integration with standard fixtures.
• Overall length: 64.5 mm overall length provides balanced reach and tactile feedback during measurement.
• Ball size range: Part of a family offering ball sizes from Ø5.0 mm to Ø10.0 mm; other sizes can be requested via the configurator or by email.

With its combination of a lightweight yet stiff ceramic stem and a durable silicon nitride ball, this stylus delivers consistent contact geometry, reduced measurement drift, and longer service life on metal parts. The M5 connection ensures compatibility with a wide range of probing systems, while the 64.5 mm length offers comfortable reach for standard inspection tasks. This makes it a dependable choice for routine calibration, setup verification, and everyday data collection on untreated aluminium components.
