(Grammatically correct, yes. However, I would suggest, "To expand upon my point," instead. Generally better received.

As a transition, it isn't good but nor is it bad. If you're writing a drama then you'd want to avoid such transitions. If the pace of what you are writing is fast then it is perfectly acceptable.)
