This straight stylus delivers precise touch points with minimal setup time thanks to its threadless design. The tungsten carbide stem provides rigidity and durability, reducing deflection and improving repeatability across repeated measurements. The ruby ball tip options let you tailor contact radius to your surface—use the smallest ball for fine details or a larger ball for steadier contact on uneven features. Compatible clamp holders and configurable stem steps expand its use across different probing routines, making it a versatile choice for high-precision inspection, reverse engineering, and quality control workflows.
