What are the advantages of core drilling bits

Hollow core drills offer unique advantages over PDC and submersible hammer drills in certain specific application scenarios. Below is a comparative analysis of the three drill bits:
Advantages of Hollow Core Drills
Lower Cost: Hollow core drills are typically less expensive to manufacture than PDC and submersible hammer drills, making them more competitive in cost-sensitive applications.
Adaptable: Hollow core drills can drill a wide range of materials, including wood, plastics, metals and more, for a wide range of applications.
Easy to Replace: Hollow core bits are easy to replace and relatively inexpensive, reducing downtime and maintenance costs.

Adjustable Hole Diameter: Different hole diameters can be drilled by replacing different sizes of drill bits.

Advantages of PDC drills
Fast drilling speed: PDC Drill Bits have very high hardness and wear resistance, fast drilling speed and high efficiency.
Long life: The life of PDC drills is much longer than that of ordinary drills, which can reduce the number of drill replacements.
Adaptation to hard materials: PDC drill bits are especially suitable for drilling hard rock, concrete and other materials.
Advantages of Down Hole Hammer Bits
Large Diameter Drilling: PDC hammer bits are suitable for large diameter drilling, commonly used in mine blasting, foundation treatment and other projects.
Strong crushing ability: The submerged hammer drill has strong crushing ability and can effectively crush hard rocks.

Summarize
Which drill bit to choose depends mainly on the specific application scenario and material characteristics.
If you need to drill soft materials and are more sensitive to cost, hollow core drills are a good choice.
If hard materials need to be drilled quickly, PDC drills are the best choice.

If large diameter drilling or crushing of hard rock is required, a submersible hammer bit is the preferred choice.
