Klingspor 369141 3″ x 79″ CS 411 Y 40 Grit Zirconia (Blue) Sanding Belt, Stainless, Steel, & Metals

The Klingspor 369141 CS 411 Y 3″ x 79″ 40 Grit Zirconia Sanding Belt is designed for heavy material removal on stainless steel, mild steel, and various metal surfaces. This high-performance sanding belt features a blue zirconia alumina abrasive that self-sharpens during use, delivering powerful cutting action throughout the belt’s life. Its Y-weight polyester backing resists tearing under pressure, making it well-suited for use with belt grinders, pedestal sanders, and wide belt sanding machines in metal fabrication and industrial maintenance environments.

Engineered for tough jobs, this 40-grit belt is ideal for rough grinding, weld clean-up, and surface leveling on hard metals. It also includes sanding-active fillers that minimize heat buildup and reduce glazing during prolonged use on stainless steel. Whether operating in dry or wet conditions, its waterproof cloth backing and resin bonding system ensure reliable abrasive performance and long-lasting durability. The CS 411 Y belt is a heavy-duty solution for demanding professionals who need aggressive stock removal and consistent results.
