Rapid Duro 26RD3 81 Chainsaw Chain, 20 in L Bar, 0.063 ga, 0.325 in TPI/Pitch, 81-Drive Link

The Stihl RAPID™ Duro 3 chain is a low-kickback version of the Stihl RAPID™ Duro. It stays sharp up to four times longer than standard chains. With standard-sized cutters, the RD3 is extremely durable and produces very good results in all types of wood. It is especially suited for cutting dirty wood, treated wood, roots and hardwoods, which would quickly dull conventional chains. This chain must be re-sharpened with a formed diamond grinding wheel.
