Ceramic and Marble File is used as often as in the studio as the tile nipper or mosaic glass cutter.

Cutting glass and porcelain often leaves rough, jagged or sharp edges, and this is the tool you use to smooth and round them. You can also use the file to shape marble and stone.

The file has oversized, extra-wide carbide grit surfaces roughly 8 inches x 1 inch. One side is fine-grooved for finishing surfaces, and the other is rougher for removing material more aggressively.

The file is useful for smoothing dangerous broken edges in damaged mosaics.

As always, you would file broken tile when wet, misting as needed, and collect the dust in wet bag for disposal. Keeping the dust wet is an easy was to make sure it stays out of the air, and you shouldn't risk breathing construction dusts of any type, especially glass, cement, ceramics, stone, etc.
