Grinding discs may be the most commonly used diamond sanding disc may be the most commonly used diamond sanding disc on angle grinders because they remove material quickly and are fairly cost effective.
Unfortunately, due to the rigidity of the grinding wheel, sometimes the diamond sanding disc will lose too much material (raw material) when you only need to trim the working surface or the welded joint of the work surface that must be aesthetically pleasing.
This is where the diamond sanding disc enters the photo.
As the name implies, the flip-top diamond sanding disc consists of a plurality of “fluff” abrasive cloth blocks bonded to the diamond sanding disc. When the operator accidentally applies too much pressure on the workpiece (intermediate), the flexibility of the flap will be more tolerant, otherwise the wheel gouging (on the left side) will enter the work surface.
Depending on the application, diamond sanding disc of different shapes can be supplied – flat or angled, different backing materials – fiberglass, nylon or aluminium, different types of abrasives, particle size (from 36 to 120) and number of flaps diamond cutting tools – more flaps are ideal for uneven surfaces.
The cousins of the flaps, the flap wheels, are essentially the same thing, but are made for bench grinders.
Compared to the diamond sanding disc, the flap also tends to have less vibration, which means that the operator is less fatigued. Which flaps provide the best results? Everything depends on trial and error and a lot of practice! on angle grinders because they remove material quickly and are fairly cost effective.
