The DT3122‑QZ features coarse 60-grit aluminium-oxide abrasive on a 150 mm heat-resistant resin-bond backing, designed for efficient material removal on wood, painted surfaces, PVC, plaster, and light metals. A stearate non-stick coating helps resist clogging, especially on softwoods and lacquered materials. With a Quick‑Fit nylon‑loop backing and 6-hole dust-extraction design, the discs are ready for fast changes and high-performance sanding on compatible random orbital sanders.
