Diameter 76mm R32 Hydraulic top hammer thread drill bit for mining quarrying


Top Hammer Thread Drill bits

The top hammer rock 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.

Button carbide shape


Button shapeApplication

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
