Customized sizes are available, according to your drawing or sample.
3-hole razor blades are straight industrial razor blades with three precision-ground through-holes for pin-and-bolt mounting in slitting and fiber-cutting machine rotors. The 3-hole format is widely used in staple fiber cutters and converting lines because it supports repeatable positioning, fast blade swaps, and stable cutting with no lateral drift.
YISHI manufactures 3 hole razor blades for chemical fiber cutters, film slitting machines, foil cutting systems, and flexible packaging converting lines. Standard sizes are available, and custom three-hole razor blades can be produced according to your drawing, sample, or OEM part number.
