A flap wheel is a wheel made up of a series of overlapping abrasive cloth flaps arranged in a radial pattern on a strong core. The individual flaps are mounted at an angle and will wear away during use, exposing successive layers as the wheel is used.
Flap wheels are typically used for removing rust, paint, stains, and surface irregularities from metals and other hard surfaces such as marble, concrete and stone. They are also used for polishing and buffing.
They can be used for metalworking, woodworking, and auto body work. They are available in various grit sizes depending on the finish desired. They are often used with an angle grinder, and can also be used by hand.
Is a flap disc used for sanding?
Yes, a flap disc can be used for sanding. These discs are made up of overlapping abrasive flaps and are ideal for removing material from metal surfaces. They provide consistent grinding and a superior finish and can be used to grind, blend, and finish at the same time.
The flaps are designed to wear away as the disc is used, exposing new abrasive mineral to provide a longer lasting finish. They are especially well-suited for sanding in tight areas or curves and can be used on wood as well as metal surfaces.
Flap discs are easy to use and don’t produce as much dust as other sanders.
Can Flap Disc be used on wood?
Yes, flap discs can be used on wood. Flap discs are typically made from abrasive cloth with layered overlapping flaps bonded to a backing plate. This construction creates a more aggressive cutting action than other discs while providing a smooth finish.
Flap discs are most commonly used on metal, but they can also be used on soft woods as long as you choose the right disc and use it with the right technique. When selecting the right flap disc, it is important to choose one that is compatible with the speed of your grinder, as well as the intended purpose of the disc.
In general, a disc with a coarser grit and open design is better for more aggressive material removal than a finer grit and closed design. It is also important to maintain a consistent angle and pressure on the workpiece and to guide the disc, paying close attention to the tightness of the circle to avoid gouging the wood.
As with other types of discs, it is important to use caution when using feathering and blending techniques with a flap disc, as the overall speed of the disc may allow the edge of the disc to catch and pull the wood grain.
