Stihl RAPID™ Micro™ 3 is the low kickback version of Stihl RAPID™ Micro™ saw chain. RM3 retains all the performance of Stihl RM chain, with the added benefit of low kickback to reduce the risk of kickback injury. It is a taller profile chain with more mass for chainsaws with larger displacement engines. Featuring a semi-chisel type of cutter, it typically doesn't get dull as fast as a full chisel chain during normal use, making it easier to maintain. Stihl recommends using low kickback, green labeled chain and green labeled reduced kickback bars on all powerheads.
