  • Patent number: 5943932
    Abstract: A bevel table saw 10 comprising a table 14 supported by a frame 12, the table 14 defining a slot 16 for a saw blade 44, and a blade assembly 30 mounted to the frame 12 below the table 14 such that, in use, a saw blade 44 of the blade assembly 30 protrudes through the slot 16 to cut workpieces on the table 14, wherein the depth of cut of the saw blade 44 is adjusted automatically when bevel cuts are made in a workpiece. As a result, clashing of the blade assembly 30 with the underside of the table 14 or he frame 12 is automatically avoided, thereby simplifying se of the table saw 10 during the making of bevel cuts.
