What I have found is that if I just set the "Bottom Height Offset" to a value of .010", then the end mill will extend .010" beyond the selected profile. This will cut the hole cleanly as long as the material being milled is less than .010" thicker than the expected .125".

Odd when I use MasterCAM for solidworks it does a similar thing by picking the depth of the chain selected. But like Cory I just over write the value and add .125 more to the depth. Especially in tubing. Is this not an option in hsm?
