DTH (Down the Hole) Hammer


[INQ. NO. 2209M25] This mechanical hammer is operated by compressed air. The upper part is connected to a drill pipe from the rotary head of the drilling machine, the lower part a bit. It is a critical item to the efficiency of drilling.

As the most efficient tool for the rock drilling, the piston which alternately moves up and down at 1200 – 1800 times/min, in cylindrical housing hits a bit connected to the drill pipe.

Button Bits
While hammer hitting, the button bit transmits energy directly to the rock base and accomplishes its function of cracking. Its bottom is round and embedded with tungsten carbide inserts which look like buttons. The upper part is shaped like a cylinder and finished with uneven spool lines for convenient connection to the hammer.

Drilling rig
This is a sophisticated machine for drilling. It is equipped with a drilling system of rotating pressure and separation, a drainage system for discharging broken rock pieces and sludge, accessories like a winch and a clamp for operating the drill string, and hydraulic installations for self-moving and the motor (or power supply).

Its capacity and system vary according to drilling environment and usage.

Water Hammer
CSI’s water hammer is operated by high-pressure water from a water pump instead of high-pressure air from many compressors.

So, it can save energy and other resources dramatically.

Furthermore, CSI’s water hammer is designed to protect the environment by using water from the recycling system. It also needs no lubrication oil for hammering, so there is no need to worry about water and soil pollution because of oil sludge.

As a manufacturing company specialized in drilling equipment and tools, CHANG SHIN INTERNATIONAL Co.,Ltd. has been exporting its products to more than 40 countries.

Its services include designing every module needed for drilling works, producing, marketing, changing parts, consulting, and maintenance & repair. This is what helped the company secure exclusive competitiveness in the drilling industry.

One of its R&D projects is developing a state-of-the-art drilling system as a new application of DTH drilling.

Equipped with high technology and competitiveness in both the domestic and global markets, CHANG SHIN INTERNATIONAL takes pride in supplying good-quality drilling products.
