This straight stylus delivers precise contact with minimal wear, thanks to the high-quality ruby ball and the stiffness of the carbide stem. The titanium holder reduces mass while maintaining strength, helping to maintain stable tactile feedback during probing. Ideal for routine inspection tasks, fixture validation, and detailed feature measurement where consistent contact and repeatable results matter. Use it in everyday metrology scenarios, and choose the tip size that best matches the feature being measured for optimal accuracy.
