PDC drill bits  (Polycrystalline Diamond Compact bit), it is the abbreviation for the polycrystalline diamond composite drill bit. It is a drilling tool commonly used in the geological drilling industry. Initially, the PDC bit could only be used in the soft shale formation because the hard interlayer would damage the drill bit. However, due to the emergence of new technologies and structural changes, PDC bits can now be used to drill hard interbeds and long hard rock formations. PDC bits are being used more and more by people, especially with the continuous improvement of PDC teeth quality, this situation is becoming more and more prominent. Let's get to know the preparation work before using PDC bit. First of all, the use of the previous bit should be carefully checked to understand the wear state of the bit gage diameter, and to check whether there is any missing damage on the bit body (missing parts such as teeth will cause damage to the bit that is about to enter the well)

With the development of technology and electronic technology, the DTH hammer has also made great breakthroughs. The DTH hammers with different types and structures have gradually entered the market. Sometimes, in order to be able to carry out mass production of the DTH hammer, it is possible to adopt a method of reducing the type of DTH hammer. The high-quality characteristics of the  DTH hammer  are shown in the mechanical transmission. The other DTH drills are mainly hydraulic transmission, which effectively utilizes the power. The DTH hammer makes the overall power loss small and the drilling cost low. Its other high quality mainly shows the reserved functional interface in the hydraulic system, which can be expanded according to the process requirements of different users. DTH hammers are widely used in mines, hydropower, transportation, slope anchorage, ground source heat pumps, etc. The drills produced have the characteristics of high drilling efficiency, low failure rate an

In order to properly use the  DTH drill bits  and ensure the drilling speed and service life of the drill bit, the following points must be noted: 1. Select the down-the-hole drill bit according to the rock condition and the type of rig. Different forms of alloy teeth and cloth teeth are suitable for drilling different rocks. 2. When installing the down-the-hole drill bit, the drill bit should be placed gently into the drill bit of the down-hole impactor card. Do not force the collision to avoid damage to the drill bit or the cardholder; 3. During the rock drilling process, it is necessary to ensure that the pressure of the downhole drilling rig is sufficient. If the impactor is interrupted, or the blast hole is not well discharged, the compressed air system of the downhole drilling rig should be inspected to ensure that there is no slag in the hole during the drilling process; 4. If metal objects are found to fall into the hole, they should be sucked out by magnets or taken o

Let's take a look at what you should know when operating the  DTH drill bits . 1. Before work, it is necessary to check whether the electrical insulation and grounding device are in good condition, and whether the various operating handles are flexible or not. 2. It is strictly forbidden to clean, repair, and oil during operation. It is not allowed to touch dangerous parts with the body or other tools. 3. It is strictly forbidden to put the cable directly on the iron duct, and it is not allowed to soak in the water. 4. When loading and unloading drills, drill pipes and impactors, the upper and lower personnel should cooperate closely. 5. When the equipment is overhauled, the driver should cooperate closely with the maintenance personnel and call for a response. 6. When operating the same lift, it is strictly forbidden to stand outside the driver's operation. 7. When lifting and lowering the large shelf, the drill pipe should be locked to prevent injury. We are 

Let us learn about some things of drilling driver should note! 1. DTH drill driver must abide by the mine "General Safety Operation Procedures for Post Work". 2. DTH drill drivers must abide by the safety regulations for commuting cars and hosting. 3. DTH drill drivers must comply with the safety regulations for the management of the cannon, the edge of the steps and the day of the run.  4. When moving the  DTH drill bits  or replacing the drill pipe, we should pay close attention to the high voltage line around it so as not to touch it. 5. When checking and handling cable and other electrical faults, the drop switch must be removed. 7. When working on a large shelf for high-altitude work, you must wear a safety helmet and a guardian, and you are not allowed to stand under the large shelf. 8. Thunderstorms and windy days are prohibited from working on high. We are  DTH drilling tools supplier , welcome to contact us!
