Precision Alignment & Assembly Kit: 0-0.15" Coaxial Centering Indicator & 50PCS Thread Checker Set, 100RPM with 6 Feelers, 27SAE/23Metric Gauges,for Milling, Boring, CNC, Auto Repair

Engineered for machinists and CNC technicians, this kit pairs a specialized 0-0.15''/0.0005'' coaxial centering indicator for milling/boring machines with 50pcs thread checker. Together, they deliver a complete setup and verification solution, enabling fast, accurate workpiece centering and instant thread identification for precision machining and mechanical assembly.

• 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
• Independent Detachable Thread Identifier：Each of the 50 thread checkers (27 Imperial/Blue, 23 Metric/Red) is fully detachable from its storage box. This allows you to remove individual gauges as needed, making it simpler to test threads in confined areas like machinery gaps or equipment recesses. The design streamlines workflow in tight workspaces
• Anodized Aluminum Build：XUNTOP bolt measuring tool crafted from lightweight aluminum alloy with an anodized surface coating, these gauges resist corrosion and wear from oils, solvents, and workshop conditions. This maintains measurement precision and extends tool longevity for reliable performance in demanding environments
