Mirka's backup pads are manufactured using top quality molded polymer construction. Each pad is balanced to eliminate vibration and provide superior finishing. The medium density polyurethane foam is firm enough to level substrates, while conforming to minor suface sontours. Pads have a maximum operating speed of 12,000 RPM.
Backup pads are available in solid face, 5 hole and multi hole vacuum patterns for super efficient vacumn sanding.
