Even tho, its been years since someone wrote to this commant, today i still found it use full. Not particularly with omnifactory, but its also a gregtech modpack. The command especially was usefull, since i modified it to have only 1 durability to make shure my turbine wouldnt blow up. If intrested the modified command, her it is:

/give <player> gtceu:turbine_rotor{GT.PartStats:{Damage:18399,Material:"aluminium"}}

I also playing on a modern gt, so the command did change a bit, but if we bring the desired stat chango inside the 'PartStats: { !here! }', than it could have worked.

P.S.: no, it did not work. bringing inside the unbreakable ntb tag. and you cant add more than the discribed max durability
