Gold Iron Mining Drill Bit Nd45 127mm Dth Hammers Bits
Hunan New Diamond offers top quality DTH hammers and bits which
have been tested in the hardest rock formation. Our bits use
quality hardened steel alloy for the bit body and premium quality
tungsten carbide buttons. With superb performance and long life
span. Our bits won high reputation among our customers.
Description
1. has higher drilling speed.
2. can provide hardening treatment in order to prolong the service
life and reduce the cost of use.
3. single impact power is large, and the power consumption of
broken rock is low.
4.piston and bit weight to have the best momentum transfer.
5. the modern theory is adopted in the structural design, which
makes the stress wave duration longer, the stress amplitude is lower, and the piston life is long.
1. Button Shape: Spherical,Semi-ballistic,Ballistic.
2. Durable performance, wear resistant and withstanding large
impacting force.
3. Long life span.
5. Fast delivery time.
Applications
The New Diamond manufactured Nd45 127mm is widely used in
geological exploration, coal mine, water well drilling, borewell
drilling, highway, railway, bridge, construction, mining, quarry,
Civil engineering, ore mining,Dimension stone industry and so on.

| WE can design and manufacture according to customers requirement of
the bit diameter,the NO.of air holes,carbide buttons and the face
shape. |
1. Long life span: the wear-resist of tungsten carbides is 10-20 times
higher compared with other similar materials, which greatly extends
the life of the carbide bits;
2. High drilling efficiency: the high grade hardness of the
carbides can always stay sharp, which could increase the drilling
speeds too;
3. Stable drilling speed: the bit is scraped and cut to break the
rock.
4. Good performance: strong wear resistance, good diameter protection which will make
the cutting teeth more efficiently.
5.Lower cost.
