Puncher

A punching is a électroportative Machine which is used to bore holes in the hard Matériaux such as the Béton or the stone.

Distinction drilling machine/punching

The punchers are distinguished from the electric Perceuse S by their " frappe" , expressed in Joule S, which is much more important than that of the hammer drills mechanical.

That comes from the difference in design of the machines:

  • the percussion of the drilling machines is produced by two discs provided with asperities in teeth of Scie, one fixes and the other interdependent one of the Mandrin, which make vibrate the Foret in the axis of drilling, aiming to disaggregate materials but being useful especially, in fact, to evacuate the residues of drilling (which interpose between the wick and material).

  • the striking of the puncher (electromechanical or electropneumatic) is created by a hammer coming to strike with force (from 3 to 10 joules) the Foret which is in Liaison slide compared to the Mandrin (slide without turning), which makes it possible to almost completely restore the energy of the hammer to the drill without interacting with the rotation movement. This combination rotation/translation of the drill facilitates drilling in difficult materials by breaking material during striking.

Use of a puncher

It is easy to distinguish a puncher from a drilling machine: the puncher does not have chuck with jaw, but it is only enough to engage the drills in the chuck (system of key, example: system patented SDS).

There exist punchers supplied with batteries, as of the multifunction punchers which can replace the drilling machine (control speed, of the directions of rotation, adapter for Foret S traditional).

The puncher, if it makes it possible to bore with facility the concrete and the hard stones such as the granite, is however disadvised for friable materials such as brick.

Lastly, it is not used for nothing " pousser" on the machine: it is enough to accompany, in order to leave with striking the greatest possible amplitude.
