Description

On unmounted flap wheels, the flaps made of coated abrasive are arranged radially around the tool axis in a fan-type structure. Their flexibility enables them to adapt perfectly to the contours of the workpiece. The abrasive grain is embedded in the sturdy, flexible cloth backing material by means of a resinoid bond.

In ISO 5429, unmounted flap wheels are designated as "flap wheels".

The ideal tool for use on angle grinders in assembly shop operations. For general applications from coarse to fine grinding.

Advantages

Highly flexible, enabling optimal adjustment to the contour.
Consistently high stock removal rate over the entire tool life as new, aggressive abrasive is constantly exposed.
Can be used face-down very close to edges and in corners thanks to special clamping system.
Can be mounted directly on the angle grinder without additional clamping devices.

Recommendations for use

Reducing the contact pressure and the peripheral speed and adding grinding oil diminishes tool wear and thermal load on the workpiece.
To increase the stock removal rate, it is advisable to use a coarser type of grit instead of increasing the contact pressure. This will prevent unnecessary tool wear and thermal load on the workpiece.
The increase in cutting speed leads to a slightly finer surface quality. Increasing the contact pressure makes the surface slightly coarser. The softer the material that is being worked on, the coarser the surface (when using the same grit size).
Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools.
For the best results, use a tool drive with an output of 1,000–1,500 watts.
For the best results, use at a recommended cutting speed of 40-50 m/s.

Safety notes

As a rule, unmounted flap wheels should be used with the appropriate clamping flanges.
The contact pressure must be significantly reduced if the specified optimum rotational speed is exceeded.
For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
The maximum permitted peripheral speed is 80 m/s.
