Overview
This 7 inch PCD cup grinding wheel is designed for aggressive floor coating removal and surface preparation. It is built for contractors who need to strip multiple coating types efficiently before moving to the next grinding step.

U.S. sellers consistently position 7 inch PCD cup wheels as removal tools for urethane epoxy, waterproofing membrane, pool deck coating, thick mastic, paint, and carpet or VCT glues. Compared with standard grinding cups, this type of wheel is sold for faster coating removal and better production on hard or sticky surfaces.

FAQ

What is this cup wheel mainly used for?
It is mainly used for aggressive removal of epoxy, glue, mastic, paint, waterproofing membrane, and other surface coatings. U.S. seller listings describe 7 inch PCD cup wheels in exactly this role.

Is this for grinding concrete or removing coatings?
This tool is mainly for coating removal and surface preparation, not for final polishing. After coating removal, the usual next step is to switch to metal bond grinding tools. That is also how U.S. competitors position this product type.

What machines can it be used on?
It is commonly used on hand-held grinders and compatible floor grinders with the correct connection. Public listings frequently mention angle grinders, floor grinders, and 5/8”-11 arbor compatibility for this category.

Can it remove waterproofing membrane and thick mastic?
Yes. Multiple public listings specifically mention waterproofing membrane and thick mastic as target materials for 7 inch PCD cup wheels.

What should I use after this tool?
After coating removal, the next step is usually a metal bond grinding tool to continue concrete preparation and move toward finer grinding or polishing stages. This follows the workflow implied by U.S. seller descriptions that place PCD cup wheels in early removal stages.
