ITP Straight Styli - Type A with Ruby Ball tip is a precision probing stylus designed for metrology and quality-control workflows. Built around a rigid carbide stem with a 31 mm overall length and an M3 thread, it delivers dependable, repeatable contact sensing in tight spaces.

• Thread: M3 thread for secure, quick mounting in compatible probe heads and fixtures.
• Tip material: Ruby ball tip provides a hard, wear-resistant contact surface for accurate measurements.
• Tip diameter range: Ruby ball sizes available from 0.5 mm to 6.0 mm; additional sizes can be requested via the configurator or by email.
• Stem material: Carbide stem delivers exceptional rigidity and dimensional stability under probing loads.
• Overall length: 31 mm, offering a compact form factor for probing small features and confined spaces.
• Design: Straight stylus optimized for everyday standard use with consistent contact geometry.

This combination of carbide rigidity and a high-quality ruby ball minimizes deflection during contact, enhancing measurement repeatability and reducing drift. The broad range of ruby ball diameters lets you tailor the contact area to feature size, from tiny cavities to larger flat surfaces. With the versatile M3 mounting, you can swap stylus tips quickly across compatible probes, reducing downtime in production environments. Ideal for tactile measurements in coordinate measuring machines (CMMs), inspection benches, and precision metrology tasks, this stylus delivers reliable performance and long service life in demanding settings.
