HD55 DTH Hammer With Thread 2 3/8'' API REG For Water Well Drilling
Product description
SOLLROC We manufacture DTH Hammers in different sizes ranging from 1'' to 12''. These hammers are made corresponding to Drilling Bits to carry out prevalent objectives. These hammers are used in various down the hole operations like bench Drilling. These are valve less hammers with optimized air cycle frequency. These are heavy duty hammers that well at greater depths demanding less air usage, delivering minimum performance loss.
DTH Hammers Specification:

| COP54, DHD350 | 5 | API 3 1/2"REG BOX | 125 | 135-155 | 5.3-6.1 | 1214 | 76.5 | 1-2.5 | 25-35 |
Product Advantages:
1. valveless air distribution. More reliable.
2. simple design of the piston, long life.
3. More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.
4. fewer internal parts, simple structure, longer life, less failure and easier to maintain becayse all the parts are heat treated.
5. It is easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
Face shape Features
Drop Center
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
Concave Face
The all-round application bit face special for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
Flat Face
This kind of face shape is suitable for very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
Product application
At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
