WoodlandPRO 71SC is a specialty narrow kerf (.043" gauge) chainsaw chain designed specifically for or pole pruners, battery powered chainsaws and carving chainsaws. This saw chain makes a thinner cut than standard 1/4" saw chain, so it requires less power from your chainsaw powerhead. WoodlandPRO 71SC is fast cutting 1/4" pitch chain, which is aggressive enough to remove large chunks of wood, yet small enough to give you tiny detail, especially when used with a carving bar. It contains no guard links so it bores with little effort. We buy WoodlandPRO saw chain in huge quantities, directly from the world's largest saw chain manufacturers, and pass the cost savings on to you. All WoodlandPRO saw chain is made with professional features, including industrial chrome plated cutters for great stay sharp qualities, and a patented alloy steel chassis to lessen stretch during break in. WoodlandPRO 71SC saw chain sharpens with a 5/32" round file or 1/8" grinding wheel.
