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. Recommendations for use .045" thickness for fast, convenient cutting with minimized burr formation. Specification: Diameter (inches): 5; Thickness nominal (inches): .045; Thickness metric (mm): 1.6; Maximum Rotational Speed (RPM): 12200; Type: Type 27; Bore Size (inches): 7/8; Abrasive: Aluminum Oxide A.
