The ITP Straight Styli - Type A with a silicon nitride ball is a precision metrology stylus designed for everyday measurement tasks in CMM and scanning workflows. With a firm M5 thread and a 65.5 mm overall length, it offers reliable contact and repeatable results for engineers and machinists working with metallic parts.

• Thread: M5 male thread for secure attachment to probes, extensions, and standard metrology setups.
• Overall Length: 65.5 mm total length provides flexible reach in tight or recessed areas.
• Stem Material: Extremely rigid carbide stem minimizes deflection for stable, high-precision probing.
• Ball Material: Silicon nitride ball chosen for durability and smooth contact, ideal when scanning untreated aluminium parts.
• Ball Size Range: Compatible with ball sizes from Ø1.5 mm to Ø10.0 mm within this product group.
• Holder Compatibility: Designed to work with standard holder sizes in this line (Ø10.0 mm, Ø11.0 mm, Ø12.0 mm), depending on the measuring system.
• Other Sizes: Additional ball sizes and configurations can be requested via the configurator or by e-mail.

This stylus combines a rigid carbide stem with a wear-resistant silicon nitride ball to deliver accurate, repeatable measurements across a range of materials. The silicon nitride ball is particularly beneficial for aluminium surfaces, helping to minimize wear and maintain consistent contact geometry. The compact 65.5 mm form factor and reliable M5 threading make it a versatile choice for routine inspection, toolmaking, and quality-control tasks, with options to tailor to specific feature sizes through other ball diameters on request.
