Gt60 102mm Top Hammer Rock Drilling Retrac Drill Bits
Top Hammer Drilling Bit
Top hammer drilling bit is mainly used for blasting hole excavation
of open pit rock drilling, underground mining, tunnelling and other
infrastructure projects. The connection mode is mainly T-threaded
connection and R-threaded connection. The top hammer hydraulic rock
drilling rods equipped with drilling rigs and open-air drilling
rigs are used to receive the energy transmitted by the rock drill
to achieve the effect of breaking the rock.
At present, the most used in engineering is the spherical bit and
the ballistic bit. Due to the special working environment of the
thread bit, we require that the thread drill bit should have high
wear resistance and impact resistance, and have sufficient
toughness to cope with the complicated and harsh working
environment. Our rock drilling bit is made of high-quality special
steel, the alloy head is made of high-strength and toughness wear-resistant alloy, and the whole
processing adopts special surface treatment, thus ensuring that our
bit is more durable and has higher fatigue resistance.

Product General Introduction:
Application: The Retrac button bits / Jack hammer bits are widely used in
metallurgy mine, geological exploration, water conservancy
construction, electricity, traffic, tunnel, quarry, national
defence stone project etc.
Material: Thread Button bits are made by high quality alloy steel bar and
tungsten carbides.
Through heat treatment, our drilling tools are tough enough to meet
rock drilling demands and have the least loss of energy while
drilling the rocks.
OEM: In addition, we can design customized thread button drill bits,
standard type or retrac type, according to different drilling
application, and custom drill bits are applicable to drill soft
rock, loose-medium rock and hard rock.

Button carbide shape
| Button shape | Application |
 | Hemispherical Buttons Universal button for all rock formations,best suited to hardest and
very abrasive rock formations |
 | Parabolic button Excellent penetration rate,but only suited to medium hard and not
so very abrasive rock formations |
 |
Conical button
For soft to medium rock hardness,more aggressive with faster
penetration rates.
|
 |
Ballistic button
Similar to Parabolic buttons,used for soft to medium hard and not
so abrasive rock formations,excellent in penetration rate |
