These unitised discs are often known as pre-polishing discs and can save a lot of traditional stages in the metal preparation and polishing process.

These unitised discs are mounted on a backing disc for directly fitting onto the flanges of angle grinders (preferably variable speed) and metal polishers. Unitised material is re-processed non-woven abrasive. By varying the hardness, formulation and abrasive mix different performance characteristics are achieved.

At their softest, FAG 4 discs are ideal for stripping paint and coatings due to their conformity. They also work well on aluminium, leaving a better finish than may be obtained with a conventional stripping disc.

SAG grades 5 & 7 are ideal for surface improvement and are often known as pre-polishing discs. Use grade 5 for polishing and grade 7 where a little more aggression is required, such as in blending ground off TIG welds.

MAG discs are more aggressive still and will leave light swirl marks. The grade MAG5 is also great on aluminium and brass, with low clogging properties. MAG will grind off small amounts of metal, leaving a fine swirl finish.
