High Quality T60 127mm Drop Center Threaded Drill Bit with 19 Buttons for Granite Drilling
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.
