The Metal Circular Slitter Blades are made of high-quality tool steel and high-alloy die steel and is suitable for slitting operating and various types of steel slitter machine. A good metal slitter for sale requires that the slitting machine blades have the smallest cutting resistance, the highest wear resistance, and the sharp and durable cutting edge. 


In the vinyl, film, fabric, paper, laminates, and non-woven industries, products are often manufactured into large, bulk material rolls. Because these rolls are too large to utilize in the end product, many industry manufacturers covert the material into smaller rolls for final production through a process called “slitting.” During this process, the material on a roll is unwound and cut into specific widths by passing through a series of blades. The blades used during the slitting process will have a significant impact on the final quality of a product. Therefore, it is important to pick the best slitting blades to use.
