4420 16” Planer with Helical Cutterhead

The Oliver 4420 16” Planer puts other planers in this class to shame. This full featured planer with a powerful 5HP motor and helical cutterhead gets the job done with ease. Built in table rollers reduce friction for rough stock and keep the material from hanging up. The powerful chain drive system positively feeds the material through a bullet proof 2 speed gear reduction box. Add the LCD readout for thickness, a built in mobile base and there’s really not much more to ask for.
