BRUIN Backer Pad - 4" Rigid

The Bruin Backer Pad - Rigid delivers a super flat, stable polishing platform that eliminates the wavy finish common with softer backer pads. Its rigid construction keeps diamond polishing pads perfectly flat under pressure, making it especially effective in tight areas like corners and staircases where control and precision matter most. Hook and loop backed with a long service life, it accepts polishing pads, sandpaper, and felt wheels, and fits most popular grinders and polishers via the standard 5/8"-11 thread — a dependable choice for fabricators, tile contractors, monumentalists, and restoration workers.
