About This

• 0.15”/0.0005” High Precision:XUNTOP coaxial centering indicator provides precise measurement of fine variations (0.0005") with 0.15" travel range. Suitable for high-speed applications where stable readings are required, improving measurement reliability in dynamic assembly processes
• 6 Feelers & 3/8"Clamping Mounting Shank: XUNTOP Co-Ax indicator set Includes 2", 4", and 6" straight/curved feelers and 3/8" mounting shank.Measures inner diameters of 5/32" to 4-1/4 "and outer diameters of 0 to 4-1/4", allowing you to quickly select feelers based on actual conditions without the need to change tools
• 100RPM Maximum Speed:Centering dial indicator supports multi-angle operation (from horizontal to vertical mounting) with a maximum recommended spindle speed of 100 RPM. Exceeding this limit may lead to measurement errors
• Easy to Use: Dial indicator can be used in any orientation—from horizontal to vertical setups, and for both internal and external diameter measurements—by simply swapping the feeler. Its face stays fixed in the desired position during spindle rotation, allowing the operator to keep both hands free for precise table alignment
• Multi-scenario Application：Coaxial indicator not only does it meet your daily needs, but it can also be applied to the daily calibration and maintenance of equipment such as lathes, grinders (external cylindrical/internal cylindrical grinders), and milling machines, ensuring the coaxiality accuracy of the spindle and chuck
