Premium Diamond Resin REZ Wheels has a textured surface are aggressive resin wheels used for cabbing, forming, contour grinding and pre-polishing stone, glass, synthetic material and even some metals. They are efficient wheels and well-suited for high volume commercial cabbing.Our Diamond Resin Napping Wheels are an excellent choice for high volume commercial cabbing. Using a proprietary technique, commercial grade diamonds are locked into a specially formulated resin-bonded belt that is mounted on a medium density foam backing with plastic center core. The medium density foam backing absorbs pressure and provides a cushion so that the wheel conforms to your stone.These wheels are manufactured with an aggressive resin bond, resulting in a rough texture with sharp points. Due to their napped nature, these wheels require a break-in period prior to working on your jewelry pieces.You can also use them on other cabbing machine brands. All wheels have 1″ arbor holes and come with bushings to accommodate 1/2″, 5/8″ and 3/4″ arbors.
