HD45A Down The Hole Hammer

4'' High Air Pressure DTH Hammer Without Footvalve HD45A For Water Well Drilling

 

Product description

A down-the-hole hammer provides a solution to the problem of removing hard rock barriers encountered in a bore. The DTH hammer resembles a small jack hammer. It screws onto the end of a drill string like a section of drill pipe. Like the jack hammers used above ground, it's air-powered with a high cyclic rate; unlike jack hammers above ground, it combines its fast-action hammer with a rotary, drilling action. This combined action rotates its chisel-like tip as it drives into the rock, breaking it into chips and dust. Because the DTH hammer is pneumatically powered, it has an air exhaust, which blows the chips and dust from the bore.

 

Product Advantages:

1. By using the latest rock drilling theory, optimizing the inside structure and the size of the air distribution, to make the DTH Hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.

2. For such projects as the drill bit break, retrieving very difficult, we specially designed a safe and reliable anti-shedding device for the bit.

3. The check valve can be replaced to the one with bigger ail controlling hole to provide more efficient cuttings discharge.

4. The top sub and the drive chuck have special thread, which can achieve an easier disassemble.

Face shape Features

Drop Center

For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.

Concave Face

The all-round application bit face special for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.

Convex Face

For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.

Flat Face

This kind of face shape is suitable for very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.

Double Gauge Face

This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.

 

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.
