how can we achieve the flute (helix)?

Depending on what program your using it can be slightly different, generally speaking through you need to draw the profile of the cut then finish that sketch and draw a helix 3d sketch for the profile to follow. Programs like Inventor and Solidworks can make this a bit more easier as they only require you to draw the profile then input the diameter, length and spacing. Hope this has helped.
