End geometry. There are up-cut, down-cut, compression cut end mills with varying numbers of flutes. End mills are intended to cut horizontally. Up-cut, down-cut and compression cut determine the way the chips (cut material) are ejected and the smoothness of the surface. With an up-cut end mill, the chips will be ejected upward and the bottom of the material will be smooth. The down-cut end ...

A feature on a variety of high performance end mills, variable helix, or variable pitch, geometry is a subtle alteration to standard end mill geometry. This geometrical feature ensures that the time intervals between cutting edge contact with the workpiece are varied, rather than simultaneous with each tool rotation. This variation minimizes chatter by reducing harmonics, which increases tool ...

The shank portion is located towards one end of the end-mill tool and is generally cylindrical (but may be tapered) for engagement by a spindle of a milling machine. In use, the milling machine rotatably drives the end-mill tool about its longitudinal axis. The body portion of the end-mill tool is located between the shank and the point. The point is formed at an opposite end of the tool from ...
