Possible to get fine finish, because the rotating speed is kept
constant even under the loaded condition.
Additionaly, when the load on the tool exceeds admissible
levels, power to the motor is reduced to protect the motor
from overheating. When the load returns to admisible levels,
the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
