The helix angle is the angle between the mill's centerline and the tangent of its cutting edge. End mills with shallower angles have cutting edges that coil around them more slowly than those with higher angles. Helix angles matter a great deal for aluminum machining. For aluminum cutting, machinists typically use 45°, 50°, and 55° helix ...
