Frequently Asked Questions

What are the benefits of polycrystalline diamond over monocrystalline?

Polycrystalline diamonds have more jagged surfaces and cutting facets, making them more effective for stropping. They are also more friable, meaning they fracture to create new sharp edges during use, providing a superior polish.

Do you offer private labeling?

Yes, we offer full OEM and ODM services, including custom logos, packaging, and buyer labeling. We work closely with distributors and brands to deliver customized solutions.

Can I get free samples before placing an order?

Absolutely. We provide free diamond stone samples to help you evaluate our product quality and performance before committing to a bulk purchase.

What is the production lead time for bulk orders?

Typical lead time is 15–25 days depending on order size and customization. We prioritize fast turnaround without compromising quality.

Are your products suitable for industrial applications?

Yes, our diamond sharpening tools are designed for both professional craftsmen and industrial use. They offer durability, precision, and consistent performance under heavy use.
