BQ-90 series dth driller is a new model drill, we develop it specially used for stone quarry and the drilled hole can be different diameter, depth, multi-orientation&angle. Now it's the indispensable products for mine quarrying, stone dynamiting and diamond wire passing.

It has following advantages:
1) Light weight, easy installation and transportation
2) The high quality pneumatic components ensure the low energy and air consumption and high efficiency
3) The good hoisting ability
4) The particular mechanical tube devices for screwing and discharging to reduce the labor intensity
5) The particular design for guiding drilling
