Cutting and Grinding Wheel Specifications:<br />
The quality of cutting and grinding wheels depends on several factors: the grain (size, shape and quality) determines how<br />
aggressive a wheel is. The right mix of bonding resins, additives and fiberglass reinforcement determines the wheel life. <strong>Metabo</strong><br />
cutting and grinding wheels are designed and manufactured in accordance with our most stringent specifications so that they,<br />
in combination with our power tools, achieve the best performance and productivity, saving time and money.<br />
