The CAT 18 in. Chainsaw Bar and Chain for CAT DG631 allows your chainsaw to keep cutting efficiently without replacing the entire chainsaw. The narrow chain gauge of .043 in. increases the cutting speed and reduces power consumption while you use the chainsaw chain. Its 62 drive links assures proper chain tension. The small diameter nose radius design of the 18 in. chainsaw chain increases safety by reducing the potential for kickback. This chain is compatible with the DG631 and DG631.9.

Looking for more information on chainsaws? Check out our guide on how to maintain a chainsaw in the product documents section.
