OREGON 72CK072G . The square ground version of Oregon’s LGX series chain. This 3/8 pitch, .050 gauge chain is ideal for high-production cutting. Blued cutters deliver high-quality protection against corrosion. Semi-skip sequence design provides greater clearance for better chip flow – the larger the wood being cut and the longer the bar used, the more important good chip flow becomes. LubriTec keeps your chain and guide bar oiled for less friction and longer life. Blued Cutters deliver high-quality protection against corrosion and exclusive OCS-01 Steel provides greater durability. Top-Plate Filing Indicators make accurate sharpening easier. For saw sizes 50-100 cc.
