Diamax Aluminum Backer Pad – 4 in., 5/8-11 Thread
The Diamax Aluminum Backer Pad is a 4 in. aluminum backer pad for backing polishing pads on flat work where a plastic or rubber body flexes.
An aluminum body does not flex, and metal carries heat away from the pad face better than plastic or rubber does.
Key Features
