SD6 DTH Drill Bits with Tungsten Carbide Button for Drill Rig Hammer Tools
Product description
Down-the-hole drilling is to drive the hammer which behind the drill bit by compressed air via the drill pipe. The piston strikes the bit directly, while the hammer external cylinder gives straight and stable guidance of the drill bit. This makes the impact of energy is not lost in joints and allowing for much deeper percussion drilling.
A down-the-hole hammer (DTH hammer) is a tool that can be attached to the end of a drill string and inserted into a bore. It's a small jack hammer used to break hard rock into small particles that can be flushed away by the DTH hammer's air exhaust
1. Capable of drilling in almost all ground conditions.
2. Constant energy directly behind bit provides speed with less power loss and greater hole accuracy.
3. Rigid drill string improves hole alignment.
4. Air flow volume provides efficient flushing and cleaner holes.
