The STIHL .325" Rapid Duro 3 Pro (RD3 Pro) saw chain is designed for use under high abrasive loads. Thanks to the carbide-tipped teeth, it is extremely robust. Even under extreme conditions or when in contact with heavily soiled wood, the saw chain maintains its high cutting quality. The STIHL 325" Rapid Duro 3 Pro saw chain stays sharp up to 10 times longer than conventional saw chains without resharpening. This makes it ideally suited for use in gardening and landscaping. The Rapid Duro 3 Pro (RD3 Pro) saw chain is equipped with a hump-shaped drive link for low vibration and reduced kickback. The drive link thickness is 1.3 mm, you can therefore cut even thicker trees and stronger branches safely and easily. Carbide saw chains are not sharpened by hand with a round file, but electrically with a sharpening machine. You are welcome to have your saw chain professionally sharpened at one of our local
authorized dealers.
