<p>A miter saw including a base having a support surface for supporting a workpiece. A turntable is mounted on the base for rotation about a vertical axis and a support is mounted on the turntable. A bevel angle adjustment mechanism is mounted on the support and includes a housing movable about a horizontal bevel angle axis. A cutting unit is connected to the housing for pivotal movement about a horizontal axis between a cutting position and a non-cutting position. The bevel angle adjustment mechanism supports cutting unit for movement in a first direction from a vertical position to a bevel angle position greater than 45° from vertical. The bevel angle adjustment mechanism also supports the cutting unit for movement in a second direction opposite to the first direction to approximately a negative 5° bevel angle position. Preferably, the miter saw further includes a biasing member, and the cutting unit is freely movable between a vertical, 0° bevel angle position and a transverse, 45° bevel angle position and movable against the force of the biasing member beyond the 0° and 45° bevel angle positions.</p> |
