SD Series High Air Pressure Drill Bits DTH Button Bits For Water Well Drilling
Product description
A down-the-hole hammer provides a solution to the problem of removing hard rock barriers encountered in a bore. The DTH hammer resembles a small jack hammer. It screws onto the end of a drill string like a section of drill pipe. Like the jack hammers used above ground, it's air-powered with a high cyclic rate; unlike jack hammers above ground, it combines its fast-action hammer with a rotary, drilling action. This combined action rotates its chisel-like tip as it drives into the rock, breaking it into chips and dust. Because the DTH hammer is pneumatically powered, it has an air exhaust, which blows the chips and dust from the bore.
Product Advantages:
1. Performance in varying reservoirs
2. Penetration rates that can outstrip other systems.
3. Reduced costs.
4. Straighter/cleaner holes.
5. Wide range of hole sizes available, without high expenditure.
6. Quieter than other percussive systems.
