Tool Overhang
Tool Overhang is defined as the distance that the tool extends from the end of tool holder (diameter to length ratio).
Cutting Forces push the tool away from the cut causing tool deflection. Cutting forces are produced by the SFM, axial depth of cut, radial depth of cut, feedrate, and material.

By keeping tool overhang to a minimum the following benefits may be achieved:
Rule of Thumb: Max overhang 8:1 for L.O.C. Max overhang 12:1 for O.A.L. |
