Rex-Cut Abrasives offers a line of cotton fiber, quick-change discs designed to remove small welds and machine tool marks as well as edge breaking, and complete related finishing tasks.
The discs are said to be rigid enough to reach into small corners, yet flexible for use on flat and contoured surfaces. Constantly revealing fresh abrasives as they work, they are made from multiple layers of reinforced, non-woven cotton that are impregnated with abrasive grains, and then pressed and bonded together, and fitted with Type R- and Type S-style fasteners.
Capable of grinding and finishing in one step, the discs provide smooth, controlled grinding action with no smearing on titanium and stainless steel, and are non-loading on aluminum, Kevlar and other composites, the company says. They are designed for use with right angle grinders and are available in 2- and 3-inch sizes with aluminum oxide and silicon carbide abrasives in seven different grain sizes and three different bonds.
