3005 008 4717 Rollomatic Chainsaw Bar, 18 in L Bar, 0.063 ga, 0.325 in TPI/Pitch, 68-Drive Link

The Rollomatic E is a general-grade laminated guide bar made of high-grade steel. Consisting of three electrically welded metal plates, it is lightweight, yet provides great stability. A sprocket is incorporated in the nose of the bar that carries the saw chain from the top to the bottom of the bar. This not only reduces wear, but also enables the Stihl Rollomatic bars designed with a narrow nose help reduce kickback tendencies. And the star-shaped sprocket can be replaced several times before the whole bar is due for replacement, increasing the service life of the bar.
