Hollow Punches are sharpened lengths of tube which are struck with a hammer against a firm surface.
Features and Uses
These are struck with a hammer to cut holes in most compliant materials (e.g. paper, card, leather, textiles).
Note: Place a piece of scrap wood, or MDF under the material to be cut and use on a sturdy bench top or similar worksurface.
- 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.
