Comparing Different Core Bits to Choose the Best for Your Exploration Core Drilling

The selection of a core bit has to be spot-on to ensure that none of your resources are wasted and are used to the best of their ability. This selection is usually based on the size and depth of any hole that is required as well as the hardness of the rock formation that is going to be drilled, the capacity of the rig that is being used, and the skill that the drilling professional possesses.

This information about three of the main drill bits that are used in exploration core drilling will help you make the right decision:

Impregnated Diamond Core Bits

Impregnated diamond core bits are generally used for exploration core drilling through hard and extremely hard rock formations. These bits can be used for drilling through almost all types of formations apart from clay, chalk, and a small number of other unconsolidated formations. Impregnated diamond core bits are not as sensitive as other types when it comes to rough handling, incorrect use, or abuse.

Surface Set Diamond Bits

Surface set diamond bits are designed more for drilling through formations that are graded between the soft and medium-hard rock. When compared to impregnated diamond core bits, these have a higher rate of penetration and can be used with lower-powered drills. However, due to only having one layer of synthetic diamonds, the bits will generally have a shorter drill life.

Poly-Crystalline Diamond Composite Bits (PDC)

PDC bits are suitable for drilling through medium to hard rock formations such as salt, limestone, and clay. The benefits of using a PDC are that they are extremely fast at drilling, are more durable and have a longer life than surface set bits, and can drill a lot faster than other types of drill bits.
