Engineered with ceramic X abrasive grains and advanced X-Form technology, it delivers exceptional stock removal performance and extended tool life. Ideal for stainless steel (Inox), high-alloy and heat-sensitive steels, as well as cast iron applications. It features a unique formula that prevents. The ceramic self-sharpening process ensures enormous stock removal on steel and stainless steel, the reinforced fabric backing makes the Eisenblätter fibre discs more durable. When combined with a matching backing pad, abrasive fibre discs are also used for the fine sanding of metals. Aluminium oxide fibre disc – the grain enables superior stock. Vulcanized fiber discs (commonly known as fiber discs) are round grinding wheels with a backing made of vulcanized fiber that is coated on one side with resin and abrasive grain.
