So I got the tool in today. Apart from the motorized trimmer, I got extra additional case holder and cutter head w/blade for the other calibers I shoot.
So here are some photos of both one of the reference .308 case that came along with the trimmer and a cutter head w/blade for my .260 (yes I know it use the same holder/case as the .308 but I want the trim length and blade fixed).
First the .308 case The reference case you can see that the deburr edge is quite shallow in angle with the chamfer edge significantly deeper (as you would hope). This reference case was not properly chamfered all the way around but I have since done one of my own and if you rotate the case after it starts to cut, you get an even chamfer all the way around.
The cutter head for the .260 is next. You can see the shallower angle for the deburr cutting surface (right) and the sharper angle for the chamfering (left). Most importantly, if you look at how the two cutting surface meet (middle), you can see that it is a smooth round interface and not a sharp edge. This guarantees that you will NOT get a knife edge.
