Production Description
Our company is specializing in drilling rigs and drilling parts for decades. We have exported to more than 30 countries all over the world. We have kinds of drilling rigs, such as DTH (Down The Hole) drilling rig, Water well drilling rig, Oil well drilling rig, Piling drilling rig with different types of Truck Mounted, Trailer Mounted and Crawler Type. For drilling parts, we have the following: DTH hammers/bits, Tricone bits, PDC Bits, Button Bits, Chisel Bits, Drill Pipe, Pick Cutters etc.
Advantage:
1. Valveless air distribution, more reliable.
2. Piston with simple but compact design, 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, with all heat-treated parts;
5. Easy to disassemble, thanks for the top sub, drive chuck and external cylinder all are connected by a multi-step thread.
