Frequently Asked Questions

What types of materials can your diamond blades cut?

Our diamond blades are designed for cutting granite, marble, porcelain tile, ceramic, concrete, brick, block, and other masonry materials.

Do you offer OEM/ODM services?

Yes, we provide OEM and ODM services. We can customize logos, packaging, blade dimensions, and specifications according to your requirements.

What is the difference between sintered and electroplated blades?

Sintered blades are made by compressing diamond powder and metal under heat, offering longer life for heavy-duty use. Electroplated blades have a single layer of diamonds bonded to the steel core, ideal for precision cutting and thinner kerfs.

Can I use your tools for wet and dry applications?

Many of our products are designed for both wet and dry use. However, we recommend checking the product specification. Wet cutting generally extends blade life and reduces dust.

What certifications do your products have?

Our factory and products are CE certified. We maintain strict quality control standards throughout the manufacturing process.
