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 SFPM, axial depth of cut, radial depth of cut, feedrate, and material.

By keeping tool overhang to a minimum the following benefits may be achieved:
  • Reduced Chatter and Vibration
  • Increased Tool Life
  • Improved part finish
  • Increased speed and feed
  • Increase in productivity


Rule of Thumb:
Max overhang 8:1 for L.O.C.
Max overhang 12:1 for O.A.L.
