This product adopts high performance brushless DC motor, with the motor efficiency higher than 87%, and service life more than 500 hours. It has the characteristics of mute, and long service life. The rear handle can be rotated 180 degrees, and the switch of the front handle can be opened 180 degrees in all directions, which is convenient for users to hold and cut on the left and right sides. The material of the blade is high strength carbon steel. After heat treatment, the hardness can reach more than 50HRC. Laser cutting and three-sided grinding are adopted to greatly improve the cutting efficiency. Flexible connection between motor and gearbox is used for the first time, which can greatly reduce shock and vibration. As independent components, the blade and gear box can be separately assembled and re-assembled with the machine body in the manufacturing process.
