Flap Sanding Disc Aluminium Oxide

A Flap Disc is an abrasive tool made to fit onto an angel grinder to grind and finish in one operation

What is GRIT on a Flap Disc

When talking about sandpaper 'GRIT' is a reference to the number of abrasive particles per inch of sandpaper.

The lower the 'GRIT' the rougher the sandpaper and conversely, the higher the 'GRIT' number the smoother the sandpaper

Flat or Conical Disc Styles

Flat -            The flap disc has a flat surface for maximum efficiency when used at 0-15° angles.  The flap disc is most suitable for grinding                      flat surfaces.

Conical -     The flap disc has a slight conical surface for grinding at 10-25° angels.  The flap disc is most suitable for grinding contoured                     surfaces.

Grit Recommendation

Grit 24-40:        Aluminium, soft con ferrous metals, wood and plastics.

Grit 36-50:        Unalloyed or low alloyed steels, and low tensile strength stainless steels.

Grit 60:              High-alloyed, stainless and tempering steels.

Grit 80:              High-alloyed steels and fine finish on all metals.

Grit 120:            For extra fine finish on all materials

To extend the service life on a flap disc, lower the speed to half of the MAX rpm rated on the disc.  This could extend the service life almost 100%.  This can be accomplished by using a variable speed angle grinder.
