The ITP Straight Stylus Type A (TKM405007102) with Ruby Ball is a precision probing accessory designed for everyday metrology and inspection tasks. It combines a lightweight, high-rigidity ceramic stem with a premium ruby contact ball for reliable, repeatable measurements in standard fixtures and probing heads.

• Overall length: 102.5 mm total length for versatile reach in common probing setups.
• Mounting thread: M4 thread for secure attachment to compatible probes and fixtures.
• Stem material: High‑performance ceramic offering low weight, high rigidity, and excellent wear resistance.
• Ball diameter range: Ruby contact ball sizes from Ø4.0 mm to Ø8.0 mm deliver precise, durable contact points.
• Customization: Other ruby-ball sizes can be requested via the configurator or by e‑mail.
• Design: Straight stylus optimized for everyday standard use and predictable contact behavior.

With this configuration, you gain stable, low-deflection contact that supports accurate measurements across repeated scans and tactile checks. The ceramic stem minimizes weight while preserving rigidity, reducing fatigue during extended use, and the ruby ball provides excellent wear resistance for long service life. This makes the stylus ideal for CMM touch probes, depth gauging, and any routine metrology task where reliable, repeatable contact matters.
