Apparatus (10) for cutting boards (19) particularly plasterboard. A locating means (12) and a cutting device (20) are mounted on an elongate graduated spacer bar (11, 27). The locating member (12) forms a T-shape with the spacer bar (11) and has a groove (17) in which the edge (18) of the board (19) is received. At least one of the locating means (12) and the cutting device (20) is slidable on the spacer bar (11) to vary the distance between a cutting blade (25) and the edge (18) of the board (19), and can be locked in position using screws (15, 24). For circular cuts (38) a pivot member (30) having a pivot spike (35) provides the locating means (12) on the spacer bar (11).
