It is also used to cut marble tiles for flooring. A masonry grinder comes in different models and sizes. Small hand-held ones are suitable for home use and usually employed for small masonry projects. There are also table-mounted models for cutting large quantities of bricks and tiles. Masonry grinders can be electric or gasoline powered and new models even have dust covers and attachment to a vacuum to suck up the dirt.
