When percussion or hammer drilling the percussion mechanism is called a DTH or down the hole hammer. This drilling tool is located directly above the down hole hammer bit. The driller transfers weight to the bit through the drill pipe as well as provides some rotation. Through the use of a compressor, the pressurized air is forced to the down hole hammer. As the drilled hole gets deeper the driller adds more drill pipe to the string. The piston strikes the impact zone of the hammer bit; hammers are always used as part of a casing advancement system and can be used in reverse circulation applications. DTH hammers are common when drilling blast holes and water wells.

Since the down hole hammer piston impacts the hammer bit directly there is a very efficient transmission of energy. This means that the impact energy does not have to pass through many other components making it possible to drill fairly deep holes.

Western Drilling Tools can easily provide all of your down hole tools including custom down hole hammers, percussion drilling tools, hammer drilling tools and more. WDT carries and distributes many major names in the down hole tools industry including Drill King, Rock More plus many others. There have been excellent advances in air flow technology which allows today’s hammers to deliver more force to the down hole tools than ever before; this enables the piston to hit harder and more frequently. In some instances it becomes difficult to hammer drill when you are under a large column of water. Fortunately, all of Western Drilling's DTH hammers come with adjustable chokes which greatly affect the performance of down hole tools. Another drilling supply that Western Drilling Tools has helped to develop is a blow back sub which can be mounted above the down hole hammer. When drilling under water, if it becomes to difficult to push the water, the blow back sub will allow some air to escape thereby lowering the average density of the surrounding water and allowing the down hole hammer to continue operating.
