This PREMIUM natural fibre disc makes derusting, deburring as well as rough grinding of various steel and stainless steel qualities easy. Mounting with zirconium aluminium oxide as well as an additional cooling layer it offers a very good removal. A special feature is the natural fiber carrier body made of jute fibre - on the one hand this is environmentally friendly, on the other hand it has a long lifetime due to its trimmability and also enables cool grinding.
