Abstract

Charging piercing unit configured, characterized in that it is provided with a covering or cover with a previous main cavity that houses a main explosive charge, with a concavity at its front end and a liner applied to the wall of said main concavity, also providing a cavity for a reinforcer in the rear part of said main cavity, which houses a reinforcing load adapted to detonate said main load and in that said drilling unit has a cavity for the indicator (33) next to the booster cavity (32) and it locates a detonator cartridge (47) next to said cover and next to the cavity of the initiator, said covering having a delimiting conformation of the main cavity, the cavity of the reinforcer and that of the indicator.
