20 PCS Abrasive Flap Wheel Sander 1 8 Shank Diameter Aluminum Oxide Flap Sanding Wheel 80 Grit Abrasive Flap Grinding Wheels for Removing Rust Deburring Grinding Polishing

The twofold advantages of a flap wheel over a traditional disk: The separate flaps each attack the workpiece surface at a slightly different angle, and this varies slightly with tool angle. This avoids the common problem with flat sheets, where they produce repeated identical scratches. Abrasive wear is distributed more evenly across the flaps, and through the length of each flap. Flaps wear from their outer ends and the sheet carrier cuts back as the abrasive coating is worn away. The wheel remains useful even as the flaps erode. Compared to flat sheets, that are discarded after only a small area of the abrasive is truly worn-out, this is a much more efficient use of the abrasive material. Features: --Perfect for sanding flat or contoured surfaces on metal,wood, rubber. --Effective after heavy -surface sanding and material removal. --Blending, deburring, and finishing applications commonly found in the metal fabrication, welding, and polishing industries. --Flap wheels are conformable to intricate shapes and contours. Designed to deliver a consistent finish with a uniform rate of cut, flap wheels wear away, continually exposing fresh abrasive. --Supporting used with straight grinder, hand drill, pneumatic tool, electric drill, pneumatic drill, bench drill, etc.
