PFERD Special line SG-PLUS cut-off wheel is suitable for stainless steel (INOX), carbon steel and all ferrous metals. Engineered for maximum productivity in high volume cutting environments. More cuts per wheel results in less down-time and increased productivity. Measurable reductions in labor cost and wheel units significantly reduce overall cutting costs. PFERDERGONOMICS recommends the thin cut-off wheels to substantially reduce vibration, noise and dust levels during use and to improve working comfort. PFERDEFFICIENCY recommends the cut-off wheels for long, fatigue-free and resource saving work, with perfect results in the shortest possible time. Recommendations for use .030" thickness for cutting sheet metal. Specification: Diameter (inches): 5; Thickness nominal (inches): .030; Thickness metric (mm): 0.8; Maximum Rotational Speed (RPM): 12200; Type: Type 1; Bore Size (inches): 7/8; Abrasive: Aluminum Oxide A.
