A thickness planer planes one side of a board at a time, giving a board of consistent thickness and with smooth surfaces. The cutter head is guided by the opposite surface of the board.
It is different to a surface planer, or jointer, where the cutter head is set into the bed surface. A surface planer has slight advantages for producing the first flat surface, and may be able to do so in a single pass. However the thicknesser has more important advantages in that it can produce a board with a consistent thickness, avoids producing a tapered board, and by making passes on each side and turning the board, may also be used for the initial preparation of an unplaned board.
