What we offer:

1. DTH Hammers

DTH hammers

The DTH is the abbreviation of Down The Hole and sometimes it is also called RAB in some markets, then the RAB is short for Rotary Air Blasting

Grands  DTH Hammers

The "DTH" is the abbreviation of "Down The Hole" and sometimes it is also called "RAB" in some markets, then the "RAB" is short for "Rotary Air Blasting".

A rotation drill rig, air compressor and the "DTH drill string" are the essential unit for DTH drilling while the "DTH drill string" is always made up of DTH drill rods, DTH hammer and DTH bits. As one of key component, the DTH hammer acts as a role of converting the air pressure to the impact energy, simultaneously transferring impact energy and rotation force to DTH bits.

As specialist manufacturer and provider of DTH drilling tools, hereby we recommend our newest generation DTH hammer which is improved by absorbing art technology, selecting superior alloy steel and robust design. It is proved by more than thousands times of test that our newest DTH hammer has longer life, lower air consumption and 15% higher penetration speed compared the conventional DTH hammer in the market. In addition, it can work at the air pressure from 6 Bar to 35 Bar(0.6~ 3.5Mpa). At last, we developed various type of DTH hammer which can be compatible with DHD, COP, QL, MISSION and SD shank of DTH bits and performs very well. Therefore, the newest generation DTH Hammer is very popular among our customers and has a good market share as soon as it launched in the market.

1, The GSE DHD series DTH hammer: The Grand GSE DHD series hammers can fit the DTH bits with DHD shank. Due to its optimized and robust design, in addition the superior material makes the DTH hammer longer life, less air consumption and 15% higher penetration speed than conventional DTH hammer in the market. The below is the specification of GSE DHD series DTH hammer:

2. DTH DRILL PIPE

Product description

Down th hole drill pipes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability. Grand DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.

Standard DTH drill pipe:

Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm,

Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;

Thread: 2 3/8" API REG, 2 7/8" API REG, 3 1/2" API REG, 4 1/2" API REG, 2 3/8 API IF, 3 1/2 API IF
