SD6 Rock Drill Bit with High Quality Steel Grade for Hard Rock Drilling
Product description
Down-the-hole drilling (DTH) essentially involves a drilling hamme at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.Our Bits are used for Construction, Water well drilling, Geothermal Drilling, Micropiles, Quarry and Mining field.

1.The high quality carbide ensures high quality and performance
2.Carbide grade options for long life in challenging applications
3.Face designs to maximize penetration rate and tool life
4.Optimized flushing designs to aid in cuttings removal and reduce weard
Face shape Features
1.Concave face
It helps in easy drilling of straight holes into both medium to hard rock. With excellent air flushing ability, it is inclusive of the high rate of penetration.
2.Flat face
It performs the best in case of hard, abrasive, and broken rocks. It is known for its slower rate of penetration than a concave-faced hammer.
3.Convex face
It is designed exclusively for offering a high rate of penetration in soft rock like limestone. It can be easily used for drilling rocks that are moderately consolidated.
