The dynamically clamped planing tool has a series of cutting knives (3), having, each one, a longitudinal tooth (5) engaging with a corresponding recess (6) in a lateral wall (2a) of each longitudinal seat (2) on a shaft (1) and designed to allow a cutting knife (3) to be positioned inside the same seat, and corresponding wedges (4) having, each one, a tapered profile with an angle ( OMEGA ) less than the opening angle ( OMEGA 1) of the seat (2) so as to lock the cutting knife (3), in a working position, against the lateral wall (2a) , under the action of a force (F), directed towards the outside of the shaft (1), due to the rotation of the latter. The seats (2) furthermore are made using a method which envisages three different passes with two different tools (9 and 10), the first of which (9) is used in the first two passes in which it is off-centre with respect to the (x) axis of the shaft (1) and it also makes a recess (8) which reproduces the external profile of the cutting knife (3) and respectively in which it is at an angle ( beta ) with respect to the (x) axis of the shaft, the second tool (10) makes the third pass and is at an angle ( alpha ) with respect to the (x) axis of the shaft (1) and makes the recess (6) of the lateral wall (2a).
