Perforateur
A punch is a metal bar about 100mm long, often tapered, that is tapped with a hammer to indent metal or push out a pin. A centre punch is used for marking holes before drilling. Tip sizes may vary from 1/16 to 1/4 in. (1.5-6mm) in diameter. A pin punch should be the same diameter as the pin, or only slightly narrower. Tip diameters are usually 1.5mm-5mm.
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. Most woodworkers prefer to use a ball-peen hammer for using punches. Punches are used to drive objects, such as nails, or to form an impression of the tip on a workpiece. Decorative punches may also be used to create a pattern or even form an image.
