A brushless electric motor offers up to 1200 in-lbs of torque as well as up to around 2000 RPM. Consequently, it provides rapid exploration rates under heavy work hence improving general performance. Many designs have a tendency to be cumbersome and dramatically heavier than corded drills, because of the weight of the battery.
