Trubbnos buttons
The best choice for soft rock conditions. Trubbnos buttons and large vertical flushing grooves effec-tively remove larger chips, greatly increasing penetration rate. And more straightness by Retac skirt.

Powerface bit

Trubbnos buttons, heavy duty (HD)
Ideal for abrasive, medium hard to hard rock. Larger Trubbnos buttons and flushing grooves give the ideal balance between service life and penetration rate. Available with a short retrac for straight holes in broken rock.

Powerface bit

Spherical buttons, standard or heavy duty (HD)
For tough conditions in hard and abrasive rock. Optimized face and body design and with standard or large spherical buttons for long service life. Available with a short retrac for straight holes in broken rock.

Powerface bit

Trubbnos buttons
Designed for medium hard to hard rock. Trubbnos buttons provide better penetration rate than spherical buttons, and a longer service life than semi-ballistic ones. Available with a short retrac for straight holes in broken rock.

Flat face bit

Spherical buttons, standard or heavy duty (HD)
Ideal for hard, medium abrasive rock. The flat face, with many spherical buttons, offer an optimized energy transfer. Available with a short retrac for straight holes in broken rock.

Dome bit

Spherical or Trubbnos buttons
Can be used as an alternative to traditional reaming equipment in a pre-drilled hole and in all types of rock formations. Optimized face design for better removal of cuttings. Available with spherical or the effective Trubbnos buttons.

T45 Drill bits

Please note: that all button bits are manufactured over-sized 0,5-2,5 mm (it depends on the size of bit and buttons), meaning that for example a 45,0 mm bit is at least 45,5 mm. as new, or the size of a 140,0 mm new bit can be 141,5 mm to 142,5 mm (it depends on the model and type of bit). This is done because of the fast initial wear on button bits. It is important to consider that the drilled hole could vary in size due to drilling conditions, drilling practices and ground formation.

T45 Epiroc Bits Bench Drilling

Tungsten carbide inserts

Use large-grain coarse-grained tungsten carbide, which has high wear resistance, impact resistance and thermal stability

Shank body

High-quality alloy steel is selected, and the stable heat treatment process makes the tooth body wear-resistant and tough

Brazing process

Through special welding process, the strength of pick welding is increased, the impact resistance is improved, and the carbide tip is not easy to fall off

Shank reinforcement

Through laser cladding, powder metallurgy technology and other technologies to protect the head of the tooth body, reduce the wear rate and extend the service life

Application

According to different applications ,King Kong Drils offers three major types round shank picks :  rotary drilling picks,road header picks,road milling picks.Mainly used for coal mining and tunnel,tunnels,ground trenching and other excavation works,   and mainly equipped with shearer,boring machine,milling machines and other equipment.  Applied to all kinds of soft and hard soil, rock and concrete layer.
