The SW 501 – aluminium oxide embedded in a soft foam core

The Klingspor abrasive sponge SW 501 is equipped with a soft core made of foam, which lets it contour perfectly to curved surfaces, profiles and other shapes. The abrasive grain is applied to both its top and its bottom side. The abrasive grain used is aluminium oxide, which is tough and hard at the same time. Just as all other grains they use for their abrasives, Klingspor makes this grain synthetically to guarantee consistent properties. Since its quality never deteriorates, synthetically made grain is also ideal for high production manufacturing industries. The abrasive sponge SW 501 is furnished with aluminium oxide, which has been applied with a close coating to leave behind only a minimum number of small gaps. This close coating provides for a high removal rate and a uniform scratch pattern. Another advantage of the close coating is the long service life it lends to the abrasive.

Washable and reusable abrasive
