A saw (10) comprises a frame, a table (12) mounted in the frame and adapted to adopt two positions. A pivot member (14) is on a first side of the table and a saw assembly (16) is pivoted (at 18) to the pivot member. A blade (26) is journalled in the assembly and a motor (22) drives the blade. A spring (124) between the pivot member and saw assembly biasses the saw assembly away from the table a slot in the table permits the blade to protrude through the table. In a first of said two positions of the table, the saw assembly is above the table and the saw is a chop saw for performing plunge cuts on workpieces supported on said first side of the table (FIG. 1). In a second of said two positions, the saw assembly as below the table and the saw is a bench saw for performing cuts on workpieces passed through the blade on a second opposite side of the table (FIG. 2). The spring acts on an intermediate element (114, 132) which has two dispositions, in a first of which the spring supports the weight of the saw assembly when the table is in its first position. In the second disposition the spring bias is released.
