The high-pressure down-the-hole hammer, whose working pressure is generally above 20kg/cm², is a kind of high-efficiency rock drilling equipment（rock drilling tools）.
Some people always try their best to compare prices when buying hammer bits（dth bits）, looking for lower-priced hammer bits（dth bits）. This is true, but it's not that the lower the price, the more you save.
There is a saying: the cheaper the more expensive! Yes, it sounds a bit self-contradictory, but there are some problems behind it. The lower the price, the higher the cost in use!
Of course, in addition to choosing the brand of hammer bits（dth bits）, we should also find ways to reduce costs from the use of hammer bits（dth bits）. Many customers let the drilling rig masters do their jobs and acted as the shopkeepers.
❖1. The joint of the dth hammer and the joint of the drill pipe（dth pipe） are all right-handed threads. We should always keep right-handed during use.
❖2. When drilling a hole, the minimum impact and driving force should be selected so that the down-the-hole drill bit（dth bits） enters the rock steadily. The propulsion force of the rock drilling should change with the weight of the down-the-hole drilling tool. The propulsion force and the drilling tool should be changed. The weight must match.
❖3. When changing rods, cover both ends of the removed drill rods to prevent ballast from entering the drill rods and finally cause wear of the hammer.
❖4. When the hammer is in use, it often encounters the stuck drill. At this time, don't reverse it in a panic, and blow the bottom of the ballast in time.
❖5. During use, you should also keep abreast of the wear and tear of the drill rod of the hammer. If it becomes thinner or cracks appear, you should replace it in time to avoid breaking and falling into the hole, which will outweigh the gain.
❖6. The hammer needs reasonable lubrication, which is also the key to prolong the service life of the hammer.
Doing these details well can extend the life of the dth hammer bit by 50%.
