Manual drill for plugs


Piercing the cork or rubber plugs used to close the laboratory containers or connect them to each other.


Set of hollow brass cylinders, placed one inside the other and crossed by a rod with a cover screwed on one end. Each of them has a sharp edge at one end and a pair of perforations at the other.


After unscrewing the cover, we select a cylinder (according to the diameter of the hole we want to drill) and we pass the rod through the holes at its end. We place it with the sharp edge on the plug to be drilled and we press and rotate it simultaneously, helping with the rod, which acts like a handle.

We continue the process until we get through the plug and, finally, we introduce the rod inside the cylinder, pushing to remove the accumulated debris.
