The QEP Glass Tile Nipper is designed to easily cut irregular shapes in glass tile, between 1/32 in. to 1/4 in. thick, without the use of conventional cutters. Use this nipper to trim glass tile to fit around pipes, cabinets, walls or create eye-catching glass mosaics. Simply hold the nipper like scissors, with the tile between the wheels, and squeeze the handles gently. The wheels do not need to turn when you are cutting.
