A hand-held miter saw (1) with an electrically powered circular saw blade (2) serves for cutting a rod (3). The miter saw comprises a table (4) for supporting the rod (3) and a guideway (5) equipped on the table (4) for aligning the rod (3) into a desired miter angle, a bearing (6) with an axis (7) extending parallel with the table (4) and consisting of a piece of tube (8) and a piece of axle (9) pivotally mounted in the tube (8), a first lever (10) connected to the tube (8) of the bearing (6) and a second lever (11) connected to the axle of the bearing (6), a cutting head (12) supporting the spindle (13) of the circular saw blade (2) in positions where the axis of rotation (14) of said spindle (13) is parallel with the axis of the bearing (6), an arm (15) which is formed on the cutting head (12) and attached to the axle of the bearing (6) or pivotally connected to the first lever (10), and a bar (16), which is attached to the tube (8) of the bearing (6) or to the first lever (10) and is supporting the table (4) in such way that the table (4) can turn about a pivot axis of the table (4) so that the guideway forms an angle with the axis (14) of rotation of the saw blade (2). The miter saw (1) has a light and inexpensive structure and can easily be transported to the area where the rod to be cut is located and here easily and rapid be operated when supported only by one or two of the hands of an operator. |
