Product Description:
The threaded drill bit is equipped with the hydraulic drilling jumbo and used for crush rock ,and it is widely used in tunnel construction, large scale mine(open and underground )and large section tunnel advance in metal mine.How to choose the drill bit design is very important for the drilling work efficiency:
Spherical buttons: The height of exposed teeth is low, mainly used in the very hard rock formation above F14, to improve wear resistance, to prevent the situation of debris, it should take lower drilling speed.
Ballistic buttons: It can expose more height of buttons, mainly used in soft rock and ordinary rock below F12, with quicker drilling speed, but encountered hard rock, very easily to happen buttons debris phenomenon.
These threaded button bits can meet different drilling requirements in all rock formations. We can offer special designs according to customer's requirements for specific work situation. The button bits can transmit intensive impact energy into the rock with the least loss of energy.
1. Face: Flat, Convex, Concave, Drop-center.
2. Carbide Button Shape: Spherical, Semi-ballistic, Ballistic and Two-step
3. Bit Shank: COP/DHD/QL/SD/MACH/BR
