Abstract: A magnetic lock for a positionable power tool of the type comprising a workpiece support table moveable relative to a tool base. The magnetic lock comprises a braking surface configured to contact an outer edge of the tool base, and a magnetic device mountable to the workpiece support table adjacent an outer edge of the tool base. The magnetic device is configured to provide a selectively variable force to push the braking surface against the outer edge of the tool base. When the braking surface is pushed against he outer edge of the tool base, the workpiece support table is substantially prevented from moving relative to the tool base.

Abstract: A miter saw is described that includes a base, a table rotatably coupled with the base, and a saw unit pivotally coupled with the base and including a motor and a saw blade coupled with the motor. At least one material support surface is moveable with respect to the base.
