Klingspor flap disc SMT 324, 125 x 22.23, K 80, per piece

Because the flaps continually bring fresh abrasive material to the front, such a disc works differently from an ordinary sanding disc or grinding disc. Below you can read what to look for when choosing and when this disc is suitable.

Size and arbor hole: does the disc fit your machine?

First check the diameter and the arbor hole. A 125 mm disc with a 22.23 mm arbor hole fits most angle grinders of this size. Also look at the maximum speed printed on the disc and compare it with the speed of your machine. Never use the disc on a machine that runs faster than the disc allows.

What does grit K80 mean?

The grit indicates how coarse or fine the disc sands. K80 is in the middle range: coarse enough to remove a fair amount of material, fine enough for a neat transition. A lower value sands coarser and faster, a higher value gives a finer surface. Many users work in steps, for example first with a coarser grit and then with K80 to finish the surface.

Using a flap disc 125 K80 and working safely

Always wear safety glasses, hearing protection and gloves, and make sure the workpiece is held firmly in place. Hold the grinder at a slight angle and work with moderate pressure, so that the flaps wear evenly. Too much pressure heats the workpiece and shortens the life of the disc. Check the disc for damage before use and let the machine run freely for a moment before touching the workpiece.
