The CGW 4.5” x 7/8” T27 A3 Flap Disc for Aluminum is a breakthrough in aluminum grinding technology. With premium Blue-fired Aluminum Oxide grains, calcium stearate coating, and heated treated polyester backing this disc will stay cool and prevent loading on softer materials. This disc works by the A3 Material with Calcium Stearate coating becoming liquefied as heat builds and in doing so drops the temperature on the material.
