Calcined Aluminum Sharpness Flap Disc for Wood and Metal Applications

Flap Disc Selection Guide

1. Grit Size: The grit size of a flap disc determines how coarse or fine the finish will be. Lower grit sizes (such as 40 or 60) are more aggressive and are suitable for heavy material removal, while higher grit sizes (such as 120 or 180) provide a smoother finish. Consider the type of material you will be working with and the level of finish you desire when choosing the grit size.

2. Disc Diameter: Flap discs come in a range of sizes, typically ranging from 4 inches to 7 inches in diameter. The size of the disc you choose will depend on the size of the grinder you are using and the area you need to cover. Larger discs are more efficient for larger surface areas, while smaller discs are more maneuverable in tight spaces.

3. Backing Material: The backing material of a flap disc affects its durability and flexibility. Fiberglass backing is common and provides a good balance of strength and flexibility. However, for heavy-duty applications, you may want to consider a stronger backing material such as plastic or metal.
