Abstract: A miter saw has a supporting table, a rotation device which can rotate about a vertical axis relative to the supporting table, a miter arm which particularly can rotate about the vertical axis, and a saw device arranged on the miter arm. The saw device is arranged above the supporting table to be movable up-and-down and/or to be pivotable. The rotation device has a rotation base with a recess and an insert arranged in the recess, wherein the insert preferably at least partially borders a sawing slot. The miter saw has a high cutting quality and a safe support of the workpiece is produced in that the insert and/or the recess are constructed in such a manner that the insert can be adjusted in its height and/or the vertical alignment of the insert can be adjusted relative to the supporting table and/or relative to the rotation base.
