DS DTH Hammers
DRILLING SUPPLY DOWN THE HOLE HAMMERS
The DS DTH Hammer line is capable of being mounted on many different types of drilling machines that utilize a top head or Kelly drive mounting configuration. The drill rig must be capable of maintaining a sufficient amount of air pressure and volume, lubrication, torque. rpm, hold down and hold back.
Exhaust air from the hammer is passed through blowholes in the drill bit and is used to flush clean the drilled hole. Rotation occurs from drive motor at the top of the drill string; however, this is not to be confused with the rotary drilling method. Feed force is transmitted to the hammer via the hold down unit and the weight of the drill pipe. This Line is designed to allow the wear sleeve to be manufactured with increased wall thickness, thus extending the service life. The wear sleeve may also be reversed during operation, thus further extending its life by as much as 200%. This DTH hammer line is used in many different applications which include but are not limited to heavy construction, mining, oil and gas, quarries. and water-wet.
