ABSTRACT:
In a triangular turnround cutting plate, in particular for precision machining, a main cutting edge (3, 3a, 3b) defines an acute angle with the adjoining auxiliary cutting edge (4a, 4b, 4). A continuous radius (R) is provided between the two cutting edges (3, 3a, 3b and 4a, 4b, 4, respectively) and the length (L) of all three sides is the same. The radius (R) is in the range of 0.15 to 0.3 times the size of the length (L) of the sides of the turnround cutting plate (1) and the center (M) of this radius (R) is arranged offset from the main cutting edge (3, 3a, 3b) at a distance (a, a1) towards the center of the turnround cutting plate (1) which is in the range of 0 to 0.3 times the radius (R).
