Grinding cups are specialized tools used for grinding and shaping various materials, particularly in the field of rock drilling and concrete cutting. These cups are typically attached to handheld grinding machines or grinding rigs and are used for specific grinding and polishing applications.

Grinding cups are widely used in the mining and quarrying sectors for grinding and shaping rock surfaces. They are particularly effective in grinding down irregularities, rough edges, or unwanted protrusions on rock formations, enabling smooth and even surfaces for further drilling or cutting operations.
