This lithium battery-powered nailer works without an air hose, power cord, or fuel gas cartridge. The tool features an original hammering method that uses air compressed by a high efficiency brushless motor. Designed so that the distance between the handle and the center of gravity is minimal, the tool reduces worker fatigue. Unlike gas-powered tools that produce explosive sounds and the smell of fuel, this tool is capable of stable nailing without the interruption that occurs with defective combustion.
