Product Description

SD4/SD5/SD6/SD8/SD10/SD12 DTH Rock Drill Hammer with Special Steel for Mining

 

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. Capable of drilling in practically any type of ground.
2. Constant energy behind the bit allows for faster drilling with less power loss and better hole accuracy.
3. Hole alignment is improved by using a rigid drill string.
4. The air flowing through the hole ensures efficient flushing and cleaner holes. With the same hammer, you may make a variety of hole diameters.
