Precision Workshop Kit: 0.0005"Digital Bore Gauge 2-6" Diameters Range & 50PCS Thread Checker Set, 27SAE/23Metric Gauges, for Engine Cylinder, Machining, CNC, Automotive

Designed for professional machinists and automotive technicians, this kit combines a 0.0005 inch aiccuracy aigital bore gauge and 50pcs thread checker set. Together, they provide a complete dimensional verification solution, enabling precise internal diameter measurement and rapid thread identification for engine rebuilding, CNC machining, and complex assembly, ensuring fit and compatibility.

• 0.0005” Precision Deep Bore Gauge : XUNTOP digital bore gauge covers 50-160mm (2-6") diameter and 150mm (6") depth,delivering ≤0.5m/s response time and 0.01mm (0.0005") resolution for rapid detection of micro deviations. Its anti-corrosion copper sleeve integrates a hardened M2.5mm (0.098") threaded tip (500k+ cycles) and optical glass sensor (±0.001mm stability), paired with a rigid Φ8mm (0.31") shaft to minimize bending, ensuring long-term accuracy in demanding environments
• Two-point contact probe:XUNTOP bore gauge’s two-point contact design detects ovality/taper (≤±0.005mm) while self-centering heads self-align on uneven surfaces. The all-metal lock with instant springback secures positioning, paired with a hardened probe (HRC60+) and chrome handle resist wear. This system reduces adjustment and wear during repetitive deep-bore (150mm/6") tasks, ensuring stability in high-vibration environments
• High-Contrast LCD & Zero-Setting: The digital bore gauge combines a high-contrast LCD for clear visibility in low-light conditions with instant mm/inch unit conversion, minimizing reading errors across measurement standards. Integrated with zero-setting function for rapid recalibration at any position, it eliminates manual adjustments and reduces operator fatigue
• 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
