Re: [CAD_CAM_EDM_DRO] Using a porter cable router to cut aluminum

There is currently another thread active here at
this group about the very same thing. The problems the
other person was having was that an end mill bit with
a helical cut will be pulled out of the bit holder on
a router. because of the spiral twist on a end mill
bit the rotational force is converted to a linear
pulling force, combine that with vibration and you get
slippage.
