Specialized helix angles for Aluminum are typically either 35°, 40°, or 45°. Variable helix tools are also available and make a great choice for reducing chatter and harmonics while also increasing material removal rates. A helix angle of 35° or 40° is a good choice for traditional roughing and slotting applications.

On an end mill with a 30 degree helix angle, 25 % of the force is axial and 75 % radial. On a 45 deg. helix angle, the forces are divided equally, 50 % radial and 50 % axial. High helix cutters have an helix angle of 60 deg. At a higher helix angle the radial forces are lower and cutting is smoother, vibrations lower.

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 ...
