This 450 mm (18 inch) diamond blade is specifically designed for cutting hard refractory materials. It features a Wide Gullet (WG) design with larger gaps between segments, which improves cooling and aggressively clears cutting debris. This prevents the blade from overheating or glazing, ensuring efficient performance on materials like fire brick and high-alumina block. The blade's soft bond is also optimized to maintain a sharp cutting edge, making it ideal for furnace construction and maintenance.
