Flap Discs Cut Aluminum And Other Soft Metals

Camel Grinding Wheels has expanded its line of flap discs to include discs made specifically for cutting aluminum. A calcium stearate coating that liquefies under heat keeps the discs cool in hot applications and prevents loading on soft materials. Built from blue-fired aluminum oxide grain and a polyester heat-treated backing, the 36-grit discs are available in diameters of 4 ½", 5" and 7". In addition to cutting aluminum, they can be used for brass, copper and zinc.
