Rebuilding Door Hinges

This is the kit In was looking at. Says you need a drill bit and a reamer.

That looks just like the kits I used.
I just tapped them out and tappped in the new ones.
It's possible they may have been replaced by someone else prior to me replacing them and they drilled them.
I don't know but I got the kit at oriellys.
