Features for Hydraulic Rock Drill:

The BH28 Hydraulic rock drill is a hi-tech product driven by high-pressure hydraulic oil. it adopts advanced technology and compact structure, featuring low energy consumption, small size, light weight, powerful impact energy, fast drilling, low noise, little vibration, trivial labor intensity.

It is widely applied to drill mines of marble, granite, metal, non-metal and coal mines.


The hydraulic rock drill is composed of three parts:

1. Hydraulic hammer drill

2. Hydraulic power station (Electric power or diesel engine model)

3. Fully hydraulic pushing leg

According to different engineering requirements, we can offer various supporting devices, which are for different working conditions


Drilling performance:

1. applicable to hard, semi-hard and soft rocks;

2. drilling diameter from 32mm to 45mm, while drilling granite of rigidity 7.6 degree, the drilling speed can reach over 700mm-1000mm/min, depth up to 9m.

Its efficiency and performance overmatch foreign counterparts.
