6 Inch DHD360 Alloy Steel Down The Hole Hammer For Construction Sites

Product description

In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to actuate the hammer and flush the cuttings. The drill pipes are added to the drill string successively behind the hammer as the hole gets deeper.

Product Advantages:

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

2.Adapt to hard rock and rock formation conditions (compared to top hammer).
3.Highly efficient in hard rock drilling (compared to the rotary drilling).

DTH Hammer specification:

Shank Length(less bit) External diameter Top Sub Thread Weight(less bit) Hole Range
DHD360/COP64 1248mm 148mm API 3 1/2''REG 100kg 155-190
SD6 1261mm 148mm API 3 1/2''REG 100kg 155-190
QL60 1212mm 148mm API 3 1/2''REG 95kg 155-190

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.
