Bosch premium-grade wheels are constructed of high-quality material for metal, concrete, masonry, pipeline, asphalt and stainless steel cutting. Easy-to-read labels are incorporated into the manufacturing process and therefore remain intact throughout the life of the wheel. Carefully formulated resinoid bonds are applied to meet the unique specifications of each wheel and multiple layers of long, stranded fiberglass are woven to form an exceptionally strong reinforcement layer specific to the application. Bosch uses only superior virgin grains made to exacting specifications. This accessories line is the perfect match for Bosch's trusted grinder lineup and applications include polishing, debris removal and dust extraction.
