The Oregon 72EXL072 is a 20-inch full-chisel saw chain in 3/8 pitch with .050 gauge and 72 drive links. Full-chisel cutters cut fast in clean softwood and hardwood, and the 25-degree top-plate angle with a 7/32-inch round file keeps the edge geometry consistent when you sharpen. It suits experienced cutters running pro-grade 20-inch bars who want speed over smoothness; full-chisel chain is more aggressive and less forgiving than semi-chisel, especially in dirty or frozen wood. It fits saws whose drive links are stamped 72, A1 or 76 (46, 47, 51 or 80 on Husqvarna) and that take 72 drive links of 3/8 .050 chain.
