Frequently Asked Questions

What materials are your diamond coated end mills suitable for?

Our diamond coated tools are specifically engineered for machining graphite, carbon fiber reinforced plastics (CFRP), high-silica aluminum, ceramics, and other abrasive non-ferrous materials.

What is the difference between CVD and SDC coatings?

CVD (Chemical Vapor Deposition) diamond coating provides a thick, wear-resistant layer ideal for roughing and high-abrasion applications. SDC (Special Diamond Coating) is a thinner, smoother coating optimized for finishing operations and fine surface finishes.

Do you offer custom tool solutions?

Yes, we provide OEM and ODM services. Our engineering team can customize tool geometry, coating type, and dimensions to meet your specific application requirements.

What is your minimum order quantity (MOQ)?

Our standard MOQ is 10 pieces per item, but we can accommodate sample orders and small batches for evaluation purposes.

How do I place an order?
