pointeau -> punch (tool)

Un pointeau est un poinçon (généralement en acier) qui sert à marquer l'empreinte pour un trou à percer.
Le pointeau est toujours pointu, il ne faut le pas confondre avec le chasse-goupille. L'angle du cone peut varier.

pin punch

A punch is a hard metal rod with a shaped tip at one end and a blunt butt end at the other, which is usually struck by a hammer. Punches are used to drive objects, such as nails, or to form an impression of the tip on a workpiece..
