Circular knife holder is also called knife holder for round knives & Rotary Slitter Knives, are characterized by their mostly circular shape with corresponding diameter Ø. Their cutting geometries are either flat, slotted or toothed cutting edge, is mainly used in coiling machine for metal sheet like mild steel, stainless steel, aluminum,copper,galvanized sheet and cold or hot rolled plate trimming and slitting.
Knife holder below is specialized for lithium poles slitting knifes with an extremely high tolerance at thickness, flateness and concentricity.
