The ITP Straight Styli Type A with Ruby Ball is a straight, precision probe designed for standard measurement tasks. Built for metrology professionals who demand rigidity and consistent contact geometry, the Type A offers a reliable ruby-ball tip and a robust carbide stem for demanding environments.

• Overall length: 103 mm
• Thread: M4
• Ball material: Ruby ball (high-quality ruby tip for hard-wearing contact)
• Ball diameter range: Ø1.0 mm to Ø8.0 mm
• Stem material: Carbide for extreme rigidity and minimal deflection
• Connection method: Straight styli design, hand-tightened with SW5.5 open-end spanner
• Customization: Other sizes available on request via configurator or by e-mail

The combination of a carbide stem and ruby ball provides consistent, repeatable contact during probing, reducing deflection under load and delivering reliable dimension capture. With 103 mm of reach, this stylus is well-suited for features tucked into recessed areas or fixtures with limited access, while the M4 threading ensures compatibility with standard probe interfaces. The hand-tightened head enables quick on-site adjustments without tools, keeping your inspection workflow smooth and efficient. If your measurement needs require a different ball size, additional options within Ø1.0 mm to Ø8.0 mm are available by request to tailor performance to your feature size, material, and surface finish.
