Down-The-Hole(DTH) Drill Hammers

DTH hammers are used for blast hole drilling and blasting, mainly applied in Mining. Marble quarny or well drilling and other construction projects.In underground mining projects, they ensure high-efficient transmission of percussive force into the rock, high drilling accuracy and the optimal drilling outcome.

Product Introduction & Advantages

As a professional DTH drilling tools manufacturer and supplier, we have the latest generation of DTH hammers, which is improved by absorbing art technology, selecting superior alloy steel, and robust design. It is proved by more than thousands times of tests that our newest DTH hammer has a longer life, lower air consumption, and 15% higher penetration speed compared to the conventional DTH hammer in the market. Our Wooke Series 6'' high-frequency hammer (patented) is the money-saver for the new drilling era, with outstanding features in air-saving, penetration, longevity and reliability. Excellent performance in both "soft" ground and "hard formation" in terms of ROP.

1. Reliable bit retainer system, bit won't drop and rupture in complex geological conditions.
2. Driver Sub is heat-treated to achieve better abrasiveness and longer life.
3. Two-start thread driver sub is easier to be removed and installed.
4. Short and thick shank, for better energy transmission and less strain and stress during impact.Working efficiency is improved and cost-in-use is reduced.
5. Piston case: Using superior alloy steel, even better reliability and longer life after heat treatment.
6. Hardened piston after heat treatment, optimized orientating system between the piston and internal cylinder helps to achieve the best impacing efficiency and power output. The penetration rate is 20%-30% faster than products of the same specification supplied by competitors.
7. Wooke optimized structure design: Fewer air holes on the internal cylinder, higher stiffness of air slot.
8. Internal parts are tightly assembled to avoid interactive wear and the hammer's reliability is increased.
9. The patented air cycling technology helps pistons to gain super high accelerating impact energy.
10. Impacting frequency improved by30% of the same specification products. Even better performance in the soft and medium-hard rock formation. The penetration rate is guaranteed in hard rock as well.
11. All moving parts are processed with special technology of metal treatmetn, to sustain the reliability throughout the hammer's whole working life.
12. Our designer created this hammer of high frequesncy, high performance, and high reliability, which is optimized-structured and convenient of mataince, to achieve the hammer's efficiency to the fullest.

Highlights

✔ Cost saving: Proved 1-2 more holes / shift.

✔ Fuel Saving: Higher air pressure held under the same air supplied, less air consumption.

✔ Air pressure holding: Constant air maintained during entire drilling life.

✔ Longevity: Generally 4000-15000 meters depending on soft or hard ground.

Specification Parameter

DTH hammers are divided into: 

1.High air pressure with foot valve;

2.High air pressure without foot valve;

3.Medium air pressure without foot valve;

4.Low air pressure without foot valve.

High air pressure DTH hammer with foot valve:

● Valveless air distribution. More reliable.

● Simple design of the piston.long life span.

● More effcient energy transfer,faster drilling speed,lower air consumption and lower oil consumption.

● Ewer intemal parts,simple structure,long life span,less failure and easier to maintain because all the parts are heat trated.

● Easy to disassemble because the top sub,the drive chuck and the extemal cyinder are connected by muitiple steps thread.

High air pressure DTH hammer without foot valve:

● Avoid the problem happens on foot valve. Fracture,expansion and contraction.
● Lower air comsumption and higher impact frequency. 15-30% higher drilling efficiency than the bit with foot valve.
● Simpler structure and less spare parts, makes easier & cheaper maintenance.
● Heat-hardened spare parts,makes longer serving life and less problem.
● Thread connection for top sub and drive chuck,makes easier disassembly.

Medium air pressure without foot valve:

●The pressure are between 0.7 MPa and 1.75 MPa.

●Valveless hammers.

●Simple structure, esily to assemble and to disassemble, long lifespan. Higher impulse and faster drilling rate.

●Lower air consumption and lower oil consumption. A hole can bedrilled on the check valve to provide more efficient cuttings discharge.

●Especially suitable for quarrying.

Low air pressure without foot valve:

●The strong energy of single impact and the low energy consumption in rock crushing.
●The weight ratio of Piston and Bit almost reaches 1:1 to provide long effective proformance, which leads to the improved efficiency in rock crushing and the extended service life of the drilling tool.
●A good performance in central air exhaust and cuttings discharge, which reduces the repeated crushing ofrock.
●A check valve device is available to drill holes under water.
●The CIR Series DTH Hammer, an ideal drilling tool, is widely used in such industries relating to energy. transportation, metallurgy, building etc .
