I also recommend some kind of thread sealant, preferably blue loctite. [blue because it will help seal, but if you ever need to remove it, it breaks loose easily enough that you won't kill yourself like with the red], although some just use teflon tape.
Also, make sure you get ALL of those metal shavings out, but I'm sure you knew that.
Unless you've got the 2 piece fitting, then just drill, put the fitting in, and put together with loctite/other sealant around the edges and on the threads on the fitting.
