Graphite contains layers of carbon atoms. The layers slide over each other easily because there are only weak forces between them, making graphite slippery. Graphite contains delocalised electrons (free electrons).

The graphite is very soft & so graphite is used by lubricant.

Yeah,
According to me, Graphite has very smooth surface. It has one free (delocalysed) electron. Moreover, the carbon atoms present makes it's slippery.
So, It is used as a solid lubricant.
