This Oregon 20BPX077G is a replacement chainsaw chain with a .325 pitch, .050 gauge and 77 drive links. It fits 20-inch cutting-length bars and chainsaws from 38 to 62 cc. The chain has a new part number, 20BPX077, and comes in a red box.
The 20BPX Control Cut chain uses Rounded Micro Chisel cutters with small-radius working corners. The cutters are blued for durability and corrosion resistance. The chain is made from OCS-01 steel and has Lubri-Tec to reduce friction. Top-plate filing indicators guide sharpening.
To sharpen, hold the cutter at a 30-degree angle with a 3/16" file (part # 70503). The recommended depth gauge clearance is .025. This chain met the kickback performance requirement of ANSI B175.1-2012 and CSA Standard Z62.3 for low-kickback saw chain.
