Product Q&A

Q:What is the primary material of this cup wheel?

The cup wheel is made of Polycrystalline Diamond (PCD) segments, which provide superior durability and resistance to loading compared to traditional metal bond diamonds.

Q:Can this wheel be used for wet grinding?

No, the split PCD cup wheel is specifically recommended for dry use only.

Q:What types of surfaces can this wheel handle?

It is designed for use on concrete and masonry surfaces, suitable for removing thin coatings, grinding marking lines, and repairing rain-damaged concrete.

Q:Does this wheel require extra pressure during operation?

No extra pressure is needed. You should simply hold the grinder and let the aggressive PCD segments do the work.

Q:How does this wheel compare to metal bond diamond wheels?

It offers better wear resistance and does not load up or smear coatings like metal bond wheels, making it more cost-effective for aggressive removal tasks.
