Circular Razor Slitters

Industrial razor slitting, also called “core burst” slitting, is a single knife cutting process in which an ultra-thin, extremely sharp blade, either circular or straight, is held in position while a sheet of material is drawn over the blade. The sharp blade passes smoothly through the material leaving two pieces of material. Circular razor slitting requires a sharp blade with an edge radius of 0.00025 to 0.0005. A cutting edge can be too sharp or too dull too meet your cutting requirements.

We manufacture these extremely sharp razor slitter blades from many materials and for all conversion industries. Razor slitting is not ideal for all cutting processes. Typically, rotary shear slitting can achieve much faster cut speeds on many materials.
