A drywall cutting tool provides cuts in drywall material either parallel or perpendicular to a reference edge of the sheet, without repositioning the tool from the reference edge. The tool comprises a T square, with the head and stem portions immovably affixed to one another. The stem of the tool carries a slidably adjustable cutting body thereon, with the cutting body being secured through an elongate slot formed in the center of the stem portion of the device. The cutting body carries a pair of spaced apart cutting rollers or discs, and may be turned so the cutting axes of the two discs define a line either parallel or perpendicular to the reference edge of the sheet, and thus perpendicular or parallel to the stem of the tool.
