Well, i could argue about the effect on the net on Rauchnaut, as his body is completely cald not only in thick armor, but also a layer of insulation, plus, he actualy has no nervous system, similar to Meats Ghol, generating the electric impulses directly within muscle.

And i doubt that a drill is going to penetrate his armor fast enough. Unless Max can top the power of a Rausofss Mk 211, it won't pentrate in a single hit, and rotating blades, im afraid, wont help much against cermet composites, as they have abrasive proof properties similar to ceramics.
