Gt60 102mm Top Hammer Rock Drilling Retrac Drill Bits

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.
