View source for Dot Punch Buyers Guide

{{Buyers Guide Heading}}

The lowest cost option is to use a hand-held punch with a hammer but a wide range of automatic punches are available - both [https://en.wikipedia.org/wiki/Punch_(tool)#Prick_punch '''Dot Punches'''] and [https://en.wikipedia.org/wiki/Punch_(tool)#Centre '''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.
