COC CUTTERS
COC cutters (Center of Core Cutters) are precision-engineered tools designed for accurate cutting of paper cores, plastic cores, and tubular materials used in slitting and rewinding operations. These cutters ensure clean, straight, and uniform cuts, which are essential for maintaining proper core alignment and smooth machine performance.
Manufactured from high-grade tool steel or alloy steel, COC cutters undergo advanced heat treatment and precision grinding processes to achieve superior hardness, sharpness, and durability. Their finely sharpened cutting edges deliver burr-free cuts without crushing or deforming the core structure.
Designed for high accuracy, COC cutters maintain perfect center alignment during operation, ensuring consistent core lengths and high-quality output. Their robust construction allows them to perform efficiently in high-speed and continuous production environments.
