Frequently Asked Questions
What materials are used in these PDC cutters?
Our PDC cutters are made from a high-grade polycrystalline diamond layer sintered onto a tungsten carbide substrate, combining extreme hardness with high impact strength.
What is the heat resistance of the diamond composite sheet?
These products are designed with high thermal stability, capable of withstanding temperatures up to 750 ºC for short durations (approximately two minutes) during drilling operations.
Can I request customized shapes or sizes?
Yes. We offer DIY customization. You can provide your rock formation information or detailed size drawings for rectangular, triangular, fan-shaped, spherical, or conical designs.
What are the primary applications for PDC cutters?
They are widely used in oil and gas drilling, geological exploration, coal mining, and as mechanical tools for cutting high-hardness alloys, wood, and ceramics.
What is the typical delivery time for an order?
If the items are in stock, they are usually prepared for delivery within 1 week. For out-of-stock items, the lead time depends on the specific order quantity and customization requirements.
How is the quality of the products verified?
We utilize advanced detection methods including microhardness detection, metallographic microscopic observation, and direct reading spectrum analysis to ensure every batch meets ISO 9001:2008 standards.
