The DT3128‑QZ are premium-grade 150 mm hook-and-loop sanding discs designed for wet or dry sanding on wood, paint, metal, PVC, and other surfaces. Featuring 320-grit aluminum-oxide abrasive, a heat-resistant resin-bond backing, and a tough paper base, these discs deliver fine, consistent finishes while resisting tearing and heat buildup. Their stearate non-stick coating minimizes clogging, and the Quick-Fit nylon-loop backing allows fast and secure disc changes.
