These 4.5" aluminum grinding discs are balanced to avoid vibration during use and feature high tensile strength fiberglass mesh layers for maximum safety. These industrial grinding wheels are perfect for grinding aluminum and are made to be used on all soft metals. Each 4-1/2" x 1/4" x 5/8"-11 Aluminum Grinding Wheel comes with a screw on / screw off hub which eliminates the need for a locking nut and saves down time swapping out discs.
