Rotary Slitting Knives for Coil Slitter Machine are used in hot rolling mills and ferrous and non-ferrous metal processing plants. The slitting of high strength steel can be challenging, and the carbide inserted slitting blade are both strong and wear-resistant. We carefully choose carbide insert with suitable grades to find the balance between toughness and wear resistance, so that our customers can reach high production efficiency by prolonging knife working time between grinds.
