Vaagmiji might have a better explanation.
Here goes my version.
The Sudarshana Chakra is a spinning, disk-like weapon, literally meaning "vision of which is auspicious," having 108 serrated edges used by the
Hindu god Vishnu. The Sudarshana Chakra is generally portrayed on the right rear hand of the four hands of Vishnu, who also holds a
shankha (conch shell), a
Gada (mace) and a
padma (lotus). While in the Rigveda the Chakra was Vishnu's symbol as the wheel of time by the late medieval period Sudarshana Chakra emerged as an
ayudhapurusha (
anthropomorphic form), as a fierce form of
Vishnu, used for the destruction of an enemy. In
Tamil, the Sudarshan Chakra is also known as Chakkrath Azhwar (translated as Ring/Circlet of God).
The Chakra is described to have 10 million spikes in two rows moving in opposite directions to give it a serrated edge.
In Hinduism, there is are a lot of symbolism. If you try of understand the literal meaning of each term, you will have a very long day.

The chakram is a throwing weapon from
India. It is circular in shape with a sharpened outer edge and ranges in size from approximately 12–30 centimetres (4.7–11.8 in) in diameter. It is also known as chalikar meaning "circle", and was sometimes referred to in English writings as a "war-
quoit". The chakram is primarily a throwing weapon but can also be used hand-to-hand.
