The 3M Disc Resinite 16 Grit 21040 is a heavy-duty sanding disc engineered for aggressive material removal on edge sanding applications. Its coarse 16-grit resinite abrasive delivers rapid stock reduction on hardwood, engineered flooring, and concrete surfaces. The durable resin bond resists loading and extends disc life, reducing downtime between changes. Designed for compatibility with standard 21040 edger sanders, this disc provides consistent performance across multiple passes. Ideal for initial surface preparation and leveling uneven floors before finishing grits.
