You need a special kind of chain for ripping cuts, the kind that transforms raw timber into the boards and planks used in homes and businesses. Oregon's RipCut is designed specifically for chain type sawmills, producing smooth cuts with supreme efficiency. RipCut's precise ripping cuts give you a smooth surface every time you cut parallel to the wood grain.
