The FREUD “roto tool” cuts with a milling head that rotates at 27,000 rpm. A large number of materials can be worked with just one and. It is highly manageable and the work may be comfortable carried out when the bit is within the material and it can also nter when facing the material. This is possible because of the cutting speed and the small diameter of the milling head employed. The user may grip the machine by its body in order to obtain greater precision. There is a wide variety of millings heads on the market that are adapted to each type of material. Freud includes a milling head for wood and another for plasterboard.
