End mill helix angle selection | Blogs | WWW.CNCTIMES.COM

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.
