• Family: Type S stylus series
• Part number: KTM507004038

The threadless design reduces setup constraints and easing alignment in challenging access areas, making it ideal for intricate features and tight pockets. The tungsten carbide stem delivers durable performance under repeated contact, helping maintain measurement consistency across sessions. Ruby ball sizes cover a wide range of probing needs—from delicate, fine-feature measurement to broader surface mapping—while the smooth ruby surface minimizes wear on both the stylus and the workpiece. The 38.5 mm length strikes a balance between reach and rigidity, and compatibility with standard clamp holders ensures secure, repeatable mounting. For custom ball sizes beyond the listed range, you can request options via the configurator or by email to tailor the tip to your specific application.
