Camel Grinding Wheels introduces its new flap discs made specifically for cutting aluminum. Designed for higher heat generating applications, the discs contain a calcium stearate coating that liquefies under heat to keep the disc cooler and to prevent loading on soft materials. Manufactured from premium blue-fired aluminum oxide grain and a polyester heat-treated backing, the new 36-inch grit discs are available in 4-1/2", 5" and 7" diameters. Discs can be used on aluminum, brass, copper and zinc.
