These are adhesive backed sanding discs made from corundum (Not to be confused with Carborundum). The abrasive compounds are fastened onto a tough base with two different grits available.
The rotational speed should be adjusted for the material being worked; high speed for steels, medium speed for woods, and low speed for plastics.
These are suitable for working and polishing malleable cast iron, grey cast iron, high quality steels, non-ferrous metals, woods and plastics.
