I went to unscrew the radiator drain plug (drain pet****) but the head broke right off leaving the rest of it inside.

I drilled out a little bit of it so I could drain the coolant and bough a replacement plug but there are still pieces stuck inside and I cant get them out.

Should I just drill out the remaining pieces or is there a better way to get them out?

 

I was able to stick a flathead screw driver in and unscrew it quite easily.

 

Excellent!
