Stagger cut teeth

A tool for the removal of material, including a penetrating end, such tool being mobile around a rotation axis passing through such penetrating end, such tool being further provided with evacuation means for the material removed comprising at least one peripheral undercut or flute, the profile of such undercut depending from the distance z to the penetrating end and being determined by coordinates x, y such that:

• x=R cos a, y=R sin a, a=f(z) and R=g(z) where g is a positive function of z between the values z>0 and z=z max, and f is a function such that f(z max) is greater than f(0).
