Application
The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 ½”–10″). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines.
Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.
Advantages:
1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe

General.Operation
Series HD high air-press DTH are designed as a hammer drill. They differ from other rock drills,
however, through continuous operation down against the drill bit.Compressed air is led to the rock drill
thorough the dill tube string. Exhaust air is discharged through hole in the drill bit and used to flush clean
the drill hole. Rotation is delivered from a rotation unit and feed force from the feed is transferred the
DTH drill via the drill tubes.
