Cordless Planer
A cordless planer's primary function is to smooth the surface of wood, but it can also be used to smooth wood's rough end grain.It can shave and shape wood like a hand plane, a belt sander and a jointer all rolled into one.
It's also used for tapering wood. If a door is too wide, for instance, make passes with a power planer over the side of the door, adjusting the depth gauge to give a cut of the desired depth.
