Have used these before when made with the aluminum body and I had no complaints. I would unscrew the small drill adapter and chuck the body proper in a 3/8” cordless Dewalt drill. Recently bought the solid stainless body unit and from the looks of it, the cutter unit will be an item you can replace when they get dulled out. What a difference in weight with the new one vs the old style. Tried it the other day, puts a nice radius on the floor of the primer hole and cleaned off the flash metal that is so common with military brass cases. Only have to do it one time and the case is ready for the next step in your individual prep sequence. Does uniforming the flash hole make that much of a difference? I like to think it does but I take the case prep as far as I can each time I initially process once fired brass that I purchase. Part of my multi-step discipline for reworking cases and this procedure, along with primer pocket swaging of milsurp brass that is only done once also, is just part of the steps I use.
