Meet the ITP Straight Styli – Type E, a precision ruby-ball stylus crafted for metrology professionals who demand consistent, high-accuracy measurements. Designed for reliability in CMM and touch-probe workflows, this probe pairs a reinforced body with a rigid tungsten carbide stem to ensure stability across a wide range of dimensions.

• Thread: M5 thread for secure, straightforward mounting into compatible probe holders.
• Overall length: 55 mm, offering a compact profile with practical reach for touching features.
• Stem material: Tungsten carbide core delivers exceptional rigidity and long-term dimensional stability.
• Tip material: Ruby ball provides high-quality, wear-resistant contact for repeatable measurements.
• Ball diameter options: Available with ruby balls from Ø1.0 mm to Ø3.5 mm to suit different feature sizes.
• Custom dimensions: Other diameters or lengths can be requested via the configurator or by e‑mail.

This straight stylus excels in scenarios requiring precise contact on small holes, edges, and flat surfaces, while maintaining rigidity under measurement loads. The combination of a robust tungsten carbide stem and quality ruby ball minimizes deflection and wear, helping you achieve repeatable results across parts and sessions. With its 55 mm length and M5 mounting, it integrates smoothly into standard probe setups, and the option to tailor dimensions ensures you can tailor the probe to your specific measurement tasks.
