The lowest cost option is to use a hand-held punch with a hammer but a wide range of automatic punches are available - both Dot Punches and Centre Punches.
In general, Dot Punches have a sharper point (i.e. 60° instead of 90°) and need only the lower ranges of impact force (e.g. 20N to 50N).
Automatic punches are simply pushed down against the work-piece and do not need to be struck - indeed, should NOT be struck with a hammer.
