DTH hammer, also known as a countersunk drill and deep drilling machine, is a device that uses high-pressure gas as the driving force to generate high-frequency impact to achieve underground penetration. It is often used in geological exploration, rock mining, foundation engineering, building demolition, and other fields. It has the advantages of high efficiency and safety, so it has been widely used.

In principle, the DTH hammer uses the energy released after gas compression to generate high-frequency impact force, hammering the hammer head to the ground, and then pushing the hammerhead underground. As the hammerhead advances, the waste under the hammer head will be impacted into pieces and discharged to the ground through the pipe. During the operation of the DTH hammer, because the air pressure is accompanied by the ejection and compression of gas, the compression wave generated is repeatedly refracted underground and forms a wave system, which enables the down-the-hole machine to complete the penetration operation in a short period of time.

DTH hammer is widely used, mainly including the following aspects:

1. Geological exploration: In the exploration work, underground minerals or other obstacles are often encountered. Using a DTH hammer can dig holes and put in exploration equipment to better complete the exploration work.

2. Rock mining: DTH hammer can easily penetrate hard rock and break it into smaller pieces, so as to better mine these deposits.

3. Foundation engineering: Earthwork and tunnel excavation are one of the fields that require the use of a DTH hammer. Through the exploration of underground structures, the DTH hammer can be used to dig out the foundation of underground buildings after positioning.

4. Building demolition: When demolishing a building, it is often necessary to remove the deeper part of the wall and ground. At this time, the use of the DTH hammer can better carry out the drilling operation and improve the demolition efficiency.

In general, the DTH hammer is an efficient and powerful tool with a wide range of applications. Its appearance provides more room for human creativity and brings a lot of convenience to human beings.

A cone bit is a commonly used drill bit, usually made of steel, with a tapered structure to cut through rock and soil more easily. The tip of the drill bit is usually covered with carbide or diamond to increase its wear resistance and life. DTH hammer tapered bits are widely used in mining, construction, cement, and other fields, and can be used in mineral mining, piling, construction of building foundations and underground pipelines, and other projects.
