165mm Tungsten Carbide Button High Air Pressure DTH Bit M60 For Mining
Product description
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
The hard alloy steel bit used in drilling in hard macadam is not
only beneficial to rock breaking, but also has a longer life than
the diamond bit.The drilling speed is low, the centrifugal force is
small, and the impact of the drilling tool on the hole wall is
small. Moreover, this drilling method uses high frequency impact on
the hole bottom to reduce the influence of hole deviation on the
broken or inclined formation, thus improving the verticality of the
drilling hole and reducing the rock collapse of the hole wall.

Product Advantages
1. 1.Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of DTH hammer designed according to newest rock drilling theory.
2.Smooth performance and long service life of DTH hammer due to high
quality alloy steel materials and advanced processing technology
adapted.
3.Low problem rate and easy to maintenance due to simple , reliable
and easy assemble and disassemble inner structure of hammer.
4.Easy to depart bit from hammer due to multi-head thread connecting
chuck and cylinder of hammer.
5.Interchangeable with DTH bit and dill pipe manufactured by many
brands all over the world.
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.
