I myself use the gimlet for all my models in which a small hole is necessary times. If you want to drill to all portholes so in huge ship models, of course, requires patience. But just for miniatures, single brackets (pins) or small holes as a guide (comes just in weapons mounts for aircraft models every now and then before) because the drill right.
The head is carried out 2-sided, even for the larger drills and the other for small drills. Pay attention to it, the drill also sit bombproof. A solid gimlet, exactly fulfills the functions that can be expected from him.
