OILOMATIC® STIHL RAPID™ Duro 3 (RD3)

The first STIHL carbide-tipped .325" saw chain stays sharp up to four times longer than standard chains.

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.

Applications: The RD3 chain is especially suited for cutting dirty wood, treated wood, roots and hardwoods.

This listing is for 1 total chain! There are no returns, no exceptions! Make sure you research before you order!

Count the drive links in your old chain this is the link that runs down in the bar you should have 74 if you have an 18" bar.
Next check to see if your drive link has a number 6 stamped in the link this will tell you that you have a .063ga chain.
