I'm sure the endmill CAN take it if you use the correct cutting parameters, as I do this all the time, in steel, tool steel, stainless and aluminium.

 

It sounds like adaptive isn't really the correct toolpath to be using if the hole is only just larger than the tool.

 

The 2D bore tool path will helix the hole to size, in one continuous helix, if you want to avoid side milling with the full length of the tool.

 

If the tool is close to the size of the hole you should also consider reducing the feedrate so the peripheral feed is correct.

 

F_resultant = (F*(D-d))/D

Where

D= hole diameter

d= tool diameter

F= the normal straight line feed for that tool
