Frequently Asked Questions
Q1: What rock formations is this PDC bit best suited for?
This bit is specifically designed for soft to medium-hard formations with a hardness rating of F ≤ 10 to F ≤ 12, depending on the specific crown profile selected.
Q2: Can the number of blades and cutters be customized?
Yes, we offer fully customizable specifications including the diameter (48mm to 350mm), number of blades, and cutter types to match your specific mining environment.
Q3: How does the parabolic profile improve drilling performance?
The parabolic profile helps balance the load across the cutters, reducing vibration and improving steerability, which leads to more stable drilling and a longer tool life.
Q4: What material is used for the bit body?
We use high-strength alloy steel (HRC 38-42) for the bit body to ensure maximum wear resistance and structural integrity during heavy-duty operations.
Q5: How do you ensure the quality of the PDC cutters?
Our cutters are made from imported diamond composite materials and undergo precision heat treatment and surface strengthening to enhance impact and wear resistance.
Q6: What is the typical lead time and production capacity?
Our facility has a production capacity of 10,000 pieces per year. For specific lead times based on order volume, please contact our support team.
