Beretta T21 tracked, diesel/hydraulic rotary drilling machine
(now fitted with roatation guard)

The innovative design of the Beretta T21 permits settings of the mast and control panel in the best possible position for the drilling of holes with any tilt angle.

The machine is perfectly suited for drilling in locations where access is restricted. The mast is easily detached from the drill fame and, by extending the hydraulic hoses, it can be positioned independently and remotely from the base. The base is mounted on retractable rubber tracks and has four hydraulic jacks for raising/leveling/stabilising the unit.

The rotary drilling head has three motors (170/85/56) rpm to suit various drilling applictions which include: diamond drilling/coring, rotary drilling, down the hole, overburden drilling and auger drilling.
