Abstract
A milling cutter comprises a shank section joined to a cutting section. The cutting section includes a plurality of peripheral blades separated by a plurality of flutes to form cutting edges extending around the cutting section in a helix direction. The helix angle is relatively large such that an axial cutting force acting on the cutting edge is greater than other cutting forces acting on the same cutting edge and on a plane normal to the axial cutting force.
