Abstract: A cutting tool, in particular a tile cutting tool, with a base body, which can be clamped into a tool-holding device of a machine tool and driven to rotate, and with a cutting head that is set with cutting particles, and at least the cutting head and the base body are comprised of separate components and that the component, which constitutes the cutting head, is designed to be replaceably fastened to the base body by a detachable connection and the base body has a receptacle for containing coolant.

Abstract: The invention is based on a cutting tool, in particular a tile cutting tool, with a base body (10), which can be clamped into a tool-holding device of a machine tool and driven to rotate, and with a cutting head (12) that is set with cutting particles (14).

Abstract: A power tool (10), in particular an angle grinder, having a housing (12) that receives an electric motor (21) and a gear (26), the motor (21) having a rotor (210) which is guided in rotor bearings (2100) and on one hand carries a collector (2102), which collector can be put into contact with a voltage source via carbon brushes (23) supported in brush plates, is made sturdier and easier to install in that the housing (12) comprises two longitudinally split housing shells (120, 121), and that the brush plates are part of a bearing bridge (24) that carries both the rotor bearing (2100) and the carbon brushes (23), and the bearing bridge (24), in the guide region of the carbon brushes (23), comprises plastic.
