Product Details

5''-127mm Black High Air Pressure DTH Bit DHD340A Use For Mining

Product description

DTH hammers and bits are widely used in open-pit mines, quarries and construction projects to maximize efficiency for customers and reduce drilling costs. In underground mining engineering, high-performance and efficient energy transfer can maximize drilling accuracy and increase customer productivity. Our down-the-hole hammer and bit can optimize the impact energy loss to the rock to the minimum, and are easy to take, efficient and fast. At the same time, they also incorporate advanced material technology and sophisticated design, which makes our down-the-hole drilling tools easy to operate and long life, bringing users a high productivity, low energy consumption, and a trustworthy user experience.

Product Advantages

1. 1.High quality carbide ensures high quality and performance.

2.Carbide grade options for long life in challenging applications.

3.Face designs to maximize penetration rate and tool life.

4.Optimized flushing designs to aid in cuttings removal and reduce wear

Face shape Features

Concave Face

1. Capable of drilling straighter holes in medium to hard rock which is broken or less consolidated

2. Offers high penetration rate in the above stated rock conditions

3. Has excellent air flushing characteristics

4. Predominant face style for majority of drilling conditions

Flat Face

1. Have a superior performance in hard, abrasive and broken rock conditions

2. They however have a slower penetration rate in comparison to a concave face bit

Convex Face

1. This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc

2. They are recognized for having excellent capability for drilling into moderately consolidated rock conditions

Product application

At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.

DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
