The atoms in graphite are in a hexagonal shape and each hexagon is connected to at least six other hexagons. There are many more layers of these hexagons which are layered over one another.
These layers can easily slip and slide over each other which makes it a good lubricant and because of the layers slipping and sliding over each other it is used as pencil lead.
Although it is used as pencil lead it is not pure graphite, it is mixed with a small amount of clay to make it much more softer and easier to write.

Answer:
Graphite is used inside pencils. It slips easily off the pencil on to the paper and leaves a black mark. Graphite is also a component of many lubricants, for example bicycle chain oil, because it is slippery.
