Designed for professional engine builders and automotive technicians, this kit pairs a high-precision digital bore gauge for cylinder measurement with a versatile torque wrench set. Together, they provide the complete solution for rebuilding and assembly—ensuring precise internal diameter verification and accurate, safe fastener torque during critical engine work and automotive repairs.

• 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
• 1/4 Torque Wrench Set: Small torque wrench is a precision drive click torque wrench with a range of 5-25 Nm, making it an essential newton meter torque wrench for delicate tasks. This adjustable torque wrench provides the accuracy and durability needed to prevent damage to small fasteners on bicycles and motorcycles, giving you confidence in every repair
• High Precision: XUNTOP 1/4 torque wrench undergoes meticulous calibration by specialized institutions, ensuring a minimal 3% error margin. This high level of precision ensure accurate torque application, providing you with reliable and consistent results. The calibration certificate serves as tangible proof of the tool's reliability
