<p>The invention concerns a tool unit for a cutting or sawing machine, comprising at least one disk shaped tool (3) having a first side (3a), a second side (3b), a peripheral edge portion (54) which is the working part of the tool, and at least one driving member (52) which is coaxial with the tool. The tool unit is characterised in that that the driving member (52) is connected or connectable to the first side (3a) of the tool, that that side of the peripheral edge portion (54) which is part of said second side (3b) of the tool defines a plane which forms a limit of the, in the axial direction, maximally projecting part of the tool unit (50), and that the driving member has at least one circumferential driving surface (64) provided to be able to cooperate with a power transmission. The invention also relates to a machine comprising a machine body, a tool carrier and at least one tool unit.</p> |
