Cross sectional flute geometry

The cross-sectional flute geometry is a decisive factor for determining the way chips flow.

The image to the right (a) shows a general-purpose cross-sectional of a general 4-flute end mill. Due to the geometry of the flute surface (convex heel part B, and a hollow A) chip flow is restricted. However (b) shows a cross-sectional view of a flute geometry with good chip discharge properties. As there is no convex heel part B the chip flow becomes smoother and the chip separation is improved. This is especially effective for high efficiency slotting.
