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.
1. Soft rock drill bit
Uses: mainly used in non-crushing hardness, hardness F=8 or less,
non-abrasive rock, it’s more suitable to take new drop center face,
the bit diameter is small, with semi-ballistic buttons or ballistic
buttons, which will be easier to discharge debris to help improve
work efficiency, the tungsten carbide wear resistance is good.
2. Medium-hard rock drill bit
Uses: used in ordinary rock hardness, hardness F=8~14, non-abrasive
rock. It’s more suitable to take flat face, the bit diameter is
bit, with spherical buttons.
3. Hard rock drill bit
Uses: mainly used in the rock hardness above F=14, non-abrasive
rock, with bigger & spherical buttons, the tungsten carbide buttons
impact resistance and wear resistance is better, but the cost is
higher than the ordinary type as its bigger button diameter.
4. Abrasive rock drill bit
Uses: mainly used in high abrasive quartz rock, and the button
diameter & height is big, with more smooth face design in order to
exclude rock slag easily, with better impact resistance and
abrasion resistance.
