(You would think so, but im still trying to get the guys in this department to understand how a torque wrench is to be used)
You should tighten them untill they strip right
. It's allways the same guy to I bet,

As far as a rigidity problems I'd say no, but you may have to take lighter cuts say 2 cuts at twice the feed if possible to 1 cut but half the feed.It's hard to say becouse of so many variables.An exsample I would give is we have parts that get slotted anywhere from .5 deep to 1.125,forever we did it with a hss endmill,an average slot lets say took 5 minutes.Now we do those same slots in half the time becouse we use a insert mill taking lighter cuts but 50 times the feed,and it's easer on the machine to boot.The endmill we use now happens to be a Isccar with one little tool,I think they go down to .375 not sure,but I do know you can push them big time.I use it in alum,cast iron,mild steel,and differant grades of stainless steel.
On a side note I had some fun today when one of the guys wanted to see what it looks like to circular interpolate a hole, (I don't do it very often becouse it's not practical with a lot of are work).I took a .6 insert mill and went down through a junk alum casting making a hole about 1. by .75 deep at a feed of 250 ipm the look on his face was priceless
