With its abrasive grains made of very hard silicon carbide in an elastic plastic binding, the SFK 655 hand block creates a very fine surface structure. Therefore, it is ideal for cleaning work and the surface finish. It is used for car repair, polishing brass, bronze and other metals, as well as for the cleaning and conditioning of suede shoes or clothing, ski edges and stainless steel sinks. The hand block is waterproof and resistant to many chemicals. Therefore, it can be used together with care products such as soap, paraffin wax or polishing pastes. Klingspor offers the practical Schleiffix hand block in a total of four grain sizes from 30 to 240.
