Arc Abrasives 37203 Resin Fiber Disc 36 Grit 4.5x0.875 in

Product Description

The ARC ABRASIVES 37203 is a resin fiber disc engineered for aggressive material removal on steel, aluminum, and other non-ferrous metals. Measuring 4.5 inches in diameter with a 0.875-inch arbor hole, this disc is built with a grain and backing construction that incorporates a grinding aid to sustain cutting performance throughout the disc's life. At 36 grit, it is suited for heavy stock removal, weld blending, and surface prep work. Licensed tradespeople and fabricators reach for this disc when a fast, consistent cut on metal is the priority.

This disc is used in metalworking, fabrication, and maintenance applications where an angle grinder is the tool of choice. It performs on flat and contoured surfaces across a range of steel alloys and non-ferrous metals including aluminum. Typical applications include weld cleanup, rust removal, deburring, and preparation of metal surfaces before coating or inspection. Its 36-grit rating makes it a strong fit for rough grinding passes rather than finishing work.
