The PRO Metal has been designed for grinding metal and is aimed at metalworkers who need a reliable and durable grinding disc. The robust PRO Metal bonded grinding disc is equipped with high-quality aluminum oxide grinding grains to efficiently grind metal and steel. The grains are combined with functional fillers and embedded in a phenolic resin matrix to ensure stability, heat resistance, and reliable grinding performance. A precision-manufactured fiberglass mesh reinforces the disc and provides additional safety. It is free of iron, so you don't have to worry about rust on your workpiece when cutting stainless steel. The disc has a bore diameter of 22.23 mm for standard angle grinders with a clamping nut.
