Sigma Green Grinding Wheels

Rex-Cut Sigma Green Grinding Wheels feature fast, chatter-free cutting action to cleanly remove and blend welds without discoloration and warping. Made from a zirconia/ceramic grain, with a proprietary bonding. Available in 4", 4-1/2", 5", and 7" diameter sizes to fit right angle grinders, these grinding wheels are available with or without hubs. Virtually iron-free, these fast cutting wheels contain only 0.035 percent iron, with less than 0.1 percent of iron, chlorine, and sulfur combined, and a bonding that is formulated to help prevent corrosion.
