TDS high pressure DTH drill powers the moving of the oil hydraulic motor, rotation, propelling and lifting, swing angle location and so on by diesel (electronic motor) driving the hydraulic oil pump. The down the hole hammers consume the pressured air only when drilling. It can save energy (fuel oil or electric quantity) as 40%~50% as the total pneumatic drill. GL-120Y is good for blasting hole in surface mine, water electric building, road construction and stone project.
