Flap Wheels Products

Portable flap wheels were made by bonding radial flaps of abrasive into a hub fitted with a spindle shank. These were intended for use with electric drills and were limited to a maximum speed of around 1,000 rpm.


Specifications of Flap Wheel Sanding Discs

With developments in abrasive coating, the sheet material could withstand greater forces and speeds. This allowed the production of abrasive sanding wheels for use with high-speed angle grinders. These disks were different in the format: flatter, like the original rigid angle grinder disks, and with the flaps arranged in a densely overlapped layout rather than radial. The extra lifetime this gave to the disk allowed their use for stock removal and metal shaping, not just finishing and polishing.


The flexibility of an emery flap wheel is an advantage for smoothing curved work and avoids the production of facets, as was a problem for rigid disks. This was taken further advantage of with the development of foam-bonded flap disc wheel. These use fewer flaps, spaced apart by a flexible foam spacer. This makes them even more flexible, thus more suited for producing a smooth finish to curved surfaces.

Advantages of Flap Wheel

Flap Wheels are made of multiple overlapping small pieces or 'flaps', bonded to a central hub.

 

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.
