Yeah, just get a 4mm drill and tap. 4mm is more surface area of threads so it will be a bit stronger, but as others already mentioned it won't be bulletproof if you abuse it.
I bought a nice Dubro metric drill and tap set for pretty cheap. It has 2, 2.5, 3, 4, and 5 mm drill and taps and a decent collet-style tap handle. Or you can buy them individually. Taps are an often overlooked tool that should be in everybodies toolbox.
