Real World Performance and Day to Day Use
The SATC flap discs are designed for sanding and grinding with a right angle grinder, and the 125mm size with 22.23 mm bore gives a straightforward fit for the stated setup. The zirconia and aluminium oxide blend is described as offering a long service life, while the multi layer fibreglass backing is intended to support strength, stability and vibration absorption.
For everyday use, the 80 grit surface is a sensible choice when the job calls for finer work such as rust removal and blending rather than coarse stock removal. The 15 degree bevel is there to improve surface contact, which helps keep the disc working efficiently.

Skip this if you need a disc for the most aggressive material removal.
