- For rough and fine boring operations beyond 4 x dia. tool overhang, it
will be a big advantage to use Silent Tools.
- In milling applications, it is more difficult to give an exact overhang ratio
when to change from solid tools to Silent Tools. For example will a 390
milling cutter (90 deg. entering angle) have more radial cutting forces
than a 210 milling cutter (10 deg. entering angle), and the risk for vibra-
tions to arise is higher. A damped tool might be necessary to maintain
good productivity.
