Atlas Copco High Air Pressure Drilling Hammer For Hard Rock Mining Down The Hole DTH Hammer
Describtion
In DTH hammers, 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 hammers a nearly constant penetration rate regardless of hole length.
• Small to medium size drilling diameters
• Works in low pressure range, capable of drilling shallow to
medium hole lengths

Advantages
| dth hammer: | dth hammer spare parts |
| More efficient energy transfer. | Valveless air distribution. More reliable. |
| Faster drilling speed, 15%-30% higher than others. | Simple design of the piston, long life |
| Lower air consumption and lower oil consumption. oil consumption is about 10% lower than others | Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated. |
| Direct factory price | Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread. |
Applications
• Underground mining
• Quarry benching operations
• Water well drilling
