High air pressure DTH hammer, with a working pressure generally above 20kg/cm², is a highly efficient rock drilling equipment.

Some customers always try their best to compare prices when buying DTH hammer and DTH drill bits, to find lower priced water well DTH drill bits, this is true, but it is not true that the lower the price the more savings.

There is a saying that the cheaper the more expensive! Yes, it may sound a bit contradictory, but behind the scenes it says something that the cheaper it is, the more costly it is to use!

Of course, in addition to choosing the brand of the DTH bit, we should also think of ways to reduce the cost from the use of DTH hammer and drill bit, the following methods, which can be used as a reference for everyone:.

❖1. The joint of DTH hammer and the joint of the drill pipe are both right-handed threads, and we should always keep the right-handed back in the process of use.

❖2. When chiseling to open the hole, you should choose the minimum impact and propulsion force to make the submerged drill bit enter the rock layer smoothly. The propulsion force of the chisel should change with the weight of the submerged drilling tool, and the propulsion force and the weight of the drilling tool should match.

❖3. When changing rods, cover both ends of the unloaded drill pipe to avoid rock ballast from entering the drill pipe and eventually causing wear to the DTH hammer.

❖4. When using, DTH hammer often encounters stuck drilling as well. At this time, do not panic and reverse the drill, but blow the bottom of the ballast in a timely and strong manner.

❖5. In use, you should also keep abreast of the wear and tear of the impactor's drill pipe. If you encounter thinning, or cracks, you should replace it in time to avoid breaking and falling into the hole, which is more than worth the loss.

❖6. DTH hammer needs reasonable lubrication, which is also the key to extend the service life of the impactor. And by doing these details well, you can extend the service life of the impactor bit by 50%.
