[@Kal-El] Needs fire chakra to liquefy, and quite a lot. I recommend either making it a jutsu (meaning also balancing it) to do it. Someone has an almost exact same ability though. 

That last one would then render the weaknesses of things being heavy null? I mean, the weaknesses of a couple of jutsu are clearly that he's slowed down because of said steel. Sooooo?

No. Let's say he's placed underwater due to a jutsu or something. He's already weighed down by, let's say, the drill but water already makes you slower. Now a heavy drill + Water = Slower then a snail. Its basically making the force of the water irrelevant to the drill's weight. He can only shift the weight.......

Meh.....why am I arguing this? I'll just drop it. More complicated then it needs to be.
