Our own developed N-type clutch system resolves disadvantages of conventional impact wrench.


  • Stable impact…Improved irregular impact which conventional tool has.
  • Compact & light weight…Much compact size compare with conventional tool and less air consumption too.
  • Stable lubrication function…Grease doesn't fly off from important part
  • Better durability…No jumping action of part like conventional wrench. Torque power doesn't deteriorate for a long period.


  • U-bolt setting work for medium/large truck.
  • Tyre setting work of heavy truck or bus.
  • Assembly/disassembly work of construction machinery.
