The Stihl RM Rapid Micro 20″ (50 cm) chainsaw chain is a genuine OEM replacement loop engineered for dependable performance across petrol and electric saws. With a 3/8″ (9.53 mm) pitch, .063″ (1.6 mm) gauge, and 72 drive links, it is designed to match guide bars stamped for this setup, including the Stihl 3003 000 5221.
Built from hardened, chrome-plated steel with semi-chisel Rapid Micro cutters, it balances smooth, controlled cutting, reduced vibration, and edge durability. This makes it a reliable choice for forestry, arborist, firewood, and estate maintenance tasks, keeping saws cutting cleanly with manageable sharpening intervals.
