Brushless Motor-Low Interference, Low Noise and Smooth Operation, The frictional force of the brushless drill is greatly reduced, the operation is smooth, and the noise is much lower, impact driver do not generate electrical sparks while operating, and radio equipment interference is greatly reduced. In this way, impact driver can deliver up to 50% more power, increasing service life and operating time by 80% Motor-Low Interference, Low Noise and Smooth Operation..
Lightweight & Ergonomic Design-- The impact driver is equipped with a LED light that could perform screwing in a dark environment. With the lock switch it is safe to use the device. The non-slip handle is very pleasant to touch due to its ergonomic design..
1550In.Lb Powerful and robust cordless impact driver-- The maximum torque is up to 1550In.Lb, the speed up to 2500RPM and the impact frequency up to 3200 IPM. It can be used for all types of work that require high torque.
With the 1/4 "quick-release chuck, you can quickly change accessories without tools..
Over-Discharge Protection & Compatible Battery --The battery has over-discharge protection, it will stop automatically after it is fully charged, which is safer, if the current is too big and the temperature is too high, it will turn off....
