Abstract

The present invention provides a technique for improving the workability of a cutting tool. According to the present invention, a cutting tool may comprise a body, a base, a sub-base and a parallel ruler. The body may have a blade that can be rotationally driven. The base may be connected to the body, while the base is placed in contact with the upper surface of the workpiece. The body may tilt in a pivotal movement about an axis substantially parallel to the cutting direction such that a cutting operation can be performed with the blade projecting laterally outward from a side of the base. The sub-base may be removably attached to the base on the side from which the blade projects. The parallel ruler may be removably attached to the base on the side on which the sub-base is attached or on the opposite side of the base, together with the sub-base or in the state in which the sub-base is not attached.
