Frequently Asked Questions

What materials can your diamond tools cut?

Our tools are designed for granite, marble, travertine, limestone, basalt, sandstone, concrete (including rebar), asphalt, ceramic, porcelain, quartz, and various metals.

Do you offer OEM or private labeling?

Yes, we provide full OEM and ODM services. We can customize logos, packaging, segment design, and bonding methods to meet your brand and technical requirements.

What is the difference between sintered and vacuum brazed tools?

Sintered tools have diamonds mixed into metal powder and pressed under heat. Vacuum brazed tools have diamonds laser-welded to the surface, offering sharper cutting and longer life for precision applications.

How do I choose the right segment for my machine?

We recommend sharing your machine model, RPM, material type, and desired cut speed. Our engineers will recommend the optimal segment geometry, bond hardness, and diamond concentration.
