4'' DTH Hammer without Foot Valve for Water Well Drilling with Bit Shank HD45A

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. Better borehole quality and accuracy
2. High performance drilling
3. Safer drilling in sensitive formations
4. cost-efficient and environmentally friendly drilling
