that is exactly right. I have a .040 radius cutter just like that here I needed for a recent project and it is definitely not designed for plunging. if you ramped in at a very shallow angle I am sure it might would work in wood but in metal you are looking at a crash. This one is double sided and makes a great radius in use. Also keep in mind that as I have found on MOST of these style cutters the actual profile of the bit is not the radius, actually the radius is there but there is a little bit of extra length on the bottom and side/top of the cutter edge to smooth the transition in case you do not get it dead nuts perfect presumably. So your actual depth of cut needs to be compensated for this distance. Most are also marked with the actual ground non cutting middle diameter for your offsets. if you stick them down with double sided carpet tape and then cut them apart and follow up with the roundover it would be easy or if nothing else leave a web in between below the level of the bottom of the roundover cutter and do your roundover profiling first and then part them off however you choose. That carpet tape is pretty damn sticky and I have cut a lot of aluminum parts that were not extremely critical dimensionally easily with it and then you can peel the parts off it after the cutting is completed. Just some random thoughts. Peace
