What the product is
The Mirka Iridium 320 is a 6-inch PSA abrasive disc designed for machine sanding in automotive and workshop environments. It suits technicians preparing surfaces for paint or clear-coat application.
What the PSA backing changes
The pressure-sensitive adhesive fixes the disc to the backing pad without holes or clips, so grit changes take seconds and the abrasive stays flat during high-speed orbiting.
Capacity and headroom
Grit 320 removes clear-coat texture and fine scratches quickly, leaving a uniform finish ready for finer grades. It will not cut deep defects or level heavy orange peel in a single pass.
