Obsidian IndustrialThe BRUIN Backer Pad - Aluminum
The BRUIN Backer Pad - Aluminum is a heavy-duty 4" backing pad engineered for precision flat polishing on granite, quartz, quartzite, marble, and concrete. Its solid aluminum body provides a rigid, stable platform that keeps diamond polishing pads flat under pressure, resists heat buildup, and outlasts plastic or rubber alternatives — all without adding unnecessary weight to your grinder or polisher.
Hook and loop faced, it fits any 5/8"-11 threaded angle grinder or polisher, making it a reliable workhorse for shop production, slab finishing, edge polishing, and scratch removal.
