Down The Hole (DTH) Drilling Tools
A wide range of products, including DTH Bits, DTH Hammer, DTH Drill Tube, ODEX & RC Drill Tools, Down The Hole (DTH) Drilling Spare Parts, Diamond Grinding Cups/Pins for Button Bits Sharpening.
Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powder to a down-the-hole bit to crush rocks.
• Our product range covers the most diverse applications in mining, natural resources exploration, water wells, quarries and civil works.
• Our products go from 3 to 25 inches drilling diameter.
• Sollroc enhances its product line with a number of accessories and peripheral products, seeking to add value to the end user of Down The Hole equipments.
Down The Hole (DTH) Hammer
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.
Suitable choice of raw material, advanced processing technology and perfect quality warranty.
With hardened treatment, drilling life can be extended and then cost can be reduced.
