The present application relates to woodworking tools in general and in particular to a woodworking grooving planer. A woodworking grooving planer comprises a planer body, a planer cutter assembly, a planer cutter lifter, an axial locking mechanism and a radial locking mechanism; the grooving planer lift comprises a rotary leadscrew, a lifting slider, a lifting base, a guide rod and a stopper; rotating the rotatory handle can make the lifting slider drive the cutter assembly to move up or down; the axial locking mechanism and the radial locking mechanism can make the rotary screw thread press the lifting slider axially and radially, so that a close thread fit is established between the rotary screw and the lifting slider, thus effectively avoiding the problem of instability and imprecision caused by pitch clearance.
