MA 90 is a Silenced pneumatic rock drill ( weight 30 kg) to be assembled on drilling slides.
It is the ideal rock drill for block cutters operating on all rocks types.
The optimal ratio between piston blows and turns allows to the rock drill a high rotation torque and therefore a high speed drilling in deep holes. The MA90 rock drill can work with air or water flushing without any modification.
