Unmounted Flap Wheel

Paired with motorized tools such as the bench grinder, mounted flap wheels are ideal for finishing the surfaces of large work projects, usually consisting of metal. The flexibility of flap wheels make them ideal for smoothing curved surfaces.

  • Used most effectively on soft metals (e.g. carbon steel)

  • Loose, hanging "flaps" lessens chatter

  • Aluminum oxide mineral cuts sharp but leaves soft, brushed finishes

  • XE-weight poly-cotton backing resists edge wear; works well with workpiece contours

Applicable for blending, deburring, and descaling, Kelco unmounted flap wheel is a general purpose flap wheel used mainly for light stock-removal and surface finishing. It is most effectively used on soft metals such as carbon steel.

 

Need a Delicate, Brushed Finish to your Project?

Individually mounted flaps with sharp-cutting aluminum oxide abrasives allows for both durability and delicate finishing of your workpiece. Such applications include refining, descaling, blending, or setting the grain.

Still, It Cuts Sharp!

Kelco unmounted flap wheel is coated with aluminum oxide mineral. This mineral is a good choice in grinding applications because of its strength, hardness,  and ability to maintain a low heat amidst the friction produced by grinding. Resin bonds the mineral to each individually mounted flap. As the wheel spins, the resin dissolves gradually. This allows for a dual effect: the abrasive is able to withstand heat and stay cool while simultaneously remain its integrity. Abrasives flaps have an X-weight poly-cotton blend backing, causing the flaps to be more flexible yet resistant to edge wear. 

As the wheels are available in grades 36 - 400, Kelco can provide the proper wheel for your unique project. Usually, coarser grades including 36 - 80 are ideal for surfaces that require a deeper, rougher score, whereas finer grades including 120 - 400 are desirable for substrates that require a shallow, fine score.

Coated abrasive flap wheels are the ideal choice for light grinding, blending, graining and scale removal on a variety of metals.

Advantages of Flap Wheel Design
Kelco unmounted flap wheels' design is based on individually affixing abrasive coated flaps around a durable, steel hub. While the flaps spin, they have a dual effect: the unwanted debris on the workpiece surface is literally swept away by the brushing motion of the flaps while the workpiece surface is left with a brushed, smooth surface.  In general, flap wheels reduce the risk for chatter and gouges on the workpiece, even on curvatures, due to their unique design. The unique design allows for the flaps to rotate centrifugally and make continuous contact with the workpiece. Because the flaps continually "lap" the surface, the wheel does not leave unwanted traces or marks, leaving a clean, brushed finish. Such finish is hard to achieve by most other discs. 

Appropriate equipment with which to use unmounted flap wheels: a variety of tools, including a backstand, match and finish sander and a centerless grinder
