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:
How to choose the bit tooth type:
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.
Processing
CNC milling and proprietary heat treatment process
Competitive Advantage
High strength chromium-molybdenum steel with high fatigue strength
and excellent wear resistance
