The Oregon 90PX052G AdvanceCut Saw Chain is a .043" gauge, 3/8" pitch, low kickback, low-vibration chain which allows homeowners and landscapers to effortlessly maintain their trees. Designed for use with small, low-powered chainsaws, 90PX offers greater chain efficiency thanks to Oregon's narrow kerf cutting systems which require less power than standard cutting systems. The chain's narrow .043" gauge makes it 15% lighter. The twin cutting corners on the low-vibration, low kickback Chamfer Chisel cutters offer outstanding performance. Always use this chain with guide bars designed for narrow kerf chain. The Oregon 90PX052G AdvanceCut Saw Chain replaces Husqvarna H38 52, Stihl 61PMM3 52, Echo 90PX52CQ and Oregon 90SG.
