But it is generated inside muscle, thus immediately triggering contraction. The net cannot destroy the eletric impulse before it appears, possibly letting a small amout reach muscle, allowing Rauchnaut to move in short jolts?

Morever, it seems that you don't quite understant the concept of [i]nano[/i]tubes: they are literaly tubes composed of carbon atoms, and together they create [i]microscopic[/i] fibers, packed into the form of muscle. Tightly bundled, you cant just slip between them, especialy after the drill will be slightly blunted by penetrating armor - they will act similar to a bulletproof vest, ableit the muscle strands are times stronger than kevlar, and thanks to the drill's circular motion, they will simply wrap around it and get it stuck while also covering the sharp edges.
