It is due to friction. And friction produces heat. For example -

Rub your hands for a while. Then put them on your face. You will realise that your hands are warm. It is due to friction.

wood resist that motion of saw so that resistance we can say as FRICTION.

when there is friction between two rubbing parts heat will generate so saw becomes warm

remember, higher the friction larger amont of heat generate. larger amount of heat make wear saw tool faster.
