The heli coil kits come with instructions and the slightly more expensive kits even come with the correct size drill bit. And you MUST use the correct size or you will pull the insert out or break the tap. It is very easy, drill, tap, put in the insert, put in the bolt. I use threadlock just to make sure the insert doesnt backout.
