Vertical Core Drill Machine

Vertical Core Drill Machine

The 305S vertical core drill machine has been design to grind concrete and stone materials. The drill motor can be connected to the rig and it doesn't need a connecting plate. It has high-quality carbon brushes imported.

The vertical core drill machine has a jackscrew for ceiling and back-wall bracing.
Through the carriage in the column, it regulates drilling rig to fit any location and this column can be tilted when is needed by loosing its two hex bolts. The vertical core drill machine has a large drilling ranging from 55 mm to 305 mm with favorable adaptation of the speed corresponding to the drilling diameter.

The vertical core drill machine is manufactured filling the European safety directives. According to these requirements, this machine is constituted by double insulation and additional earth wire to protect operator when drilling through an electric wire, as well as fitted PRCD, Portable Residual Current Device among the cords. It has triple electrical protection and double insulation earth wire-ground fault current interrupter (PRCD).

In the vertical core drill machine, the new electronic system starts the motor by soft starting avoiding high current. If the over-current threshold surpasses, the operator notices through motor pulsations. When the feed power reduces the motor works normal again. It is not required to wait seconds or minutes before starting once more like a thermal motor overload switch.

Also, the intelligent transmission of the vertical core drill machine registers the motor heat and decreases the overload threshold when exceeding the operating temperature. Thus the intelligent transmission avoids reliable overload conditions and increases safety, the operators comfort and the motor's life time. The vertical core drill machine has powerful structural strength with a firm and esthetic column. Finally, our drill has a base with anchor fixing to place and balance the machine while working.
