Innovative Design: EZ Lubrication System
A major highlight of the NC-4650H is its patented EZ Lubrication System, which offers a simple and effective self-maintenance method. This not only saves maintenance time but also significantly enhances the tool’s lifespan and performance. Compared to traditional grease injection ports, the new M7 Easy Grease Anvil further simplifies the lubrication process, making lubrication more direct and convenient.
Lubrication System Comparison
In the original air impact wrench, the lubrication oil injection port of the Regular Anvil is located beneath the street head.
After injection, it needs to be rotated slowly for even distribution.
The improved new M7 Easy Grease Anvil can be directly injected from the joint.
After injection with the Easy Grease Anvil, it quickly achieves even distribution.
In the practical test video, it can be seen that the lubricated NC-4650H quickly improves in the RPM test data, showing a significant difference compared to the original older version.
Additionally, in the test video, Vincent and Jay demonstrated the outstanding performance of the NC-4650H in tight spaces. They compared the differences between this mini pneumatic wrench and regular wrenches in practical applications, particularly emphasizing the convenience and high efficiency of the NC-4650H in operation. In the video, Vincent and Jay successfully showed how to quickly and easily disassemble bolts in extremely limited spaces, and they expressed appreciation for the tool’s compact design and powerful functionality.
Conclusion
The Mighty Seven NC-4650H mini pneumatic wrench demonstrates exceptional technical innovation and practicality, making it an ideal choice for professional technicians in busy work environments.
