A drywall joint tool includes a housing with upper and lower surfaces and an interior. A drivetrain is mounted in said interior and originates at a drive input shaft. The drivetrain reduces the rotational speed and increases the torque force from the drive input shaft to multiple rollers depending downwardly from the housing lower surface. A guide fence also depends downwardly from the housing lower surface and includes a guide wall. The spacing between the guide rollers in the guide wall correspondence to nominal and compressed thicknesses of a gypsum board panel along a cut edge traversed by the tool. In an alternative embodiment, four guide rollers are provided.
