Zirconia Flap Discs / Wheels – 4.5″, 115mm (Angle Grinder)
Excellent for polishing, sanding, grinding and finishing stainless steel, mild / black steel, all metal, plastic, copper etc.
These discs are made from Zirconia which will last much longer than the brown Alumina Oxide flap discs. They are light-weight, easy to control.
The advantages of Flap Discs are that the flaps each attack the surface at a slightly different angle, and this varies slightly with tool angle. This avoids the common problem with flat sheets, where they produce repeated identical scratches. Abrasive wear is distributed more evenly across the flaps, and through the length of each flap. Flaps wear from their outer ends and the sheet carrier cuts back as the abrasive coating is worn away. The wheel remains useful even as the flaps erode. Compared to flat sheets, that are discarded after only a small area of the abrasive is truly worn-out, this is a much more efficient use of the abrasive material.
