A preferred embodiment of a hand-operated flush cutting machine includes a front section with a first and a second disc shaped cutter blade which are rotary about an axis of rotation and mounted in the front end of an elongated tool carrier having the substantial shape of a flat bar. The tool carrier is mounted to a rear section of the machine. The rear section is provided with a number of components, including a motor for driving the cutter blades via a power transmission as well as handles and a control for operating the machine. The first, right hand side cutter blade has a first side, which does not face the second cutter blade. The first side defines a first plane which does not intersect any component in the front or rear sections.
