Our tools are widely-used in different drilling applications including mining,quarrying, water well drilling, geotechnical industries and etc.

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, 

little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

STAROCKDRILL commonly has three basic bits head designs: Flat Face, Convex and Concave. 

These are designed for specific applications for all rock types, hardness’s and conditions.

Advantages:

1. Out of the trouble of foot valve fracture and expansion and contraction.

2. lower energy consumption and higher impact frequency. 

The drilling speed is 15%-30% higher than the one with foot valve.

3. Simple structure, reliable parts, long life, easy and cheap maintenance.

4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
