That's for sure! :-) I've seen adds for holders with both a locating pin and a top clamp to hold down both insert and anvil. This arrangement would make sense at the power levels which you are referring to since it should keep the force from being concentrated at the tip.
All this is of acedemic interest to me since the only inserts I've broken have been as a result of either interupted cuts (when I shouldn't have been using carbide) or stupid mistakes. :-( Hoever, this has been interesting to see a view from a different world.
