T60 102mm Diameter Carbide Steel Material Retrac Body Rock Button Drill Bit
T60 102mm Diameter Carbide Steel Material Retrac Body Rock Button Drill Bit
Oilfield, waterwell, HDD, and geothermal drillers extensively use button bits to drill hard rock.
Button bits offer several advantages over PDC drill bits.
Two advantages are that they are
1) less expensive and
2) can drill through gravels, dolomite and very hard and abrasive limestone, making them able to withstand higher impact.

In addition to the choice of tunsten carbide button grade, how to choose the drill bit design is very important for the drilling work efficiency, also it will have a direct impact on the hole effect & vertical degree. Combined with our production and sales experience, we have summarized some of the following lessons for reference only:
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.
