The ITP Straight Styli Type A with Diamond Coated Ball (Model THM5DC5011053) combines precision with durability for professionals who demand reliable tactile probing. Designed for secure attachment to standard stylus holders, it delivers consistent, high-accuracy measurements in demanding metrology tasks.

• Thread: M5 threading for secure attachment to compatible probes.
• Overall length: 53 mm for a compact probing profile.
• Stem material: Extremely rigid carbide stem to minimize deflection and maximize accuracy.
• Ball material: Diamond-coated silicon carbide ball delivers outstanding wear resistance and a long service life.
• Ball size range: Part of a family with ball diameters from Ø1.5 mm to Ø10.0 mm; other sizes can be requested via the configurator or by email.
• Design: Straight stylus geometry provides stable, predictable contact during measurement tasks.

This combination of rigidity and wear resistance translates into more reliable data, fewer tool changes, and longer intervals between maintenance. The diamond-coated ball reduces wear on both the ball and the surface under test, helping you achieve repeatable results across repeated passes and different materials. With a 53 mm length and standard M5 thread, it integrates smoothly into existing probing setups, while the available ball sizes let you tailor contact geometry to your specific features and measurement strategy. Whether you’re inspecting micro-features, edges, or flat surfaces, this stylus delivers the precision you need for high-stakes metrology work.
