Nail Punches are available in a range of sizes. Most have a good knurled grip with either a round or square head. Good quality punches will be ground such that their tips are slightly hollow (or 'cupped') to help prevent the punch slipping off the nail head when struck.
Features and Uses
- 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.
