What are the key points in buying a core drill
When buying core drilling bits, you need to pay attention to the following points:
Geological conditions: choose a drill bit suitable for the hardness of the rock formation. Diamond bits are suitable for hard rock, and alloy bits are suitable for soft or medium hard rock.
Drill bit size: Choose the appropriate drill bit diameter according to the required wellhead diameter and the size of the core sample. Commonly used drill diameters for prospecting and coring are 41mm, 50mm, 76mm, etc.
Bit material: diamond bits are suitable for hard rock, alloy bits are suitable for soft to medium-hard rock formations.
Cooling method: Choose the appropriate cooling method (e.g. water cooling or air cooling) to improve the life of the drill bit.
Rig compatibility: Ensure that the bit is compatible with the power, speed and hydraulic system of the rig.
Core quality: Choose a bit that provides a complete and stable core.
Longevity: Choose a drill bit with good wear resistance and long life to reduce the frequency of replacement.
Brand and price: Choose a reputable brand and consider price and performance to ensure cost-effective performance. For example, pearldrill, FENGSU and other well-known brands.
Choosing the right core drilling bit through these elements can improve drilling efficiency and reduce costs.
