The electric drill relies on the motor to drive the transmission gear to
increase the strength of the drill bit, so that the drill bit can scrape through
metal, wood and other materials.

When the impact drill is working, there are two ways of adjusting knob at
the drill chuck, adjustable drill and percussion drill.
Hammer drills use the bottom motor to drive two sets of gear structures,
one set to drill, and the other set to drive the piston.
The electric pick is to let the motor drive the swinging mound to run in a
bounce mode, so that the pick has the effect of gouge the ground.
All in all, electric drills are only capable of drilling, and impact drills
also can have a slight hammering effect. The hammer drill can drill and higher
hammering, while the electric pick is only for hammering and cannot drill.
