The STIHL Rollomatic ES (STIHL Ematic Super) is composed of a solid and particuarly rigid bar with a bar nose which can be replaced entirely. It is therefore ideal for most demanding professional tasks and is used chiefly on heavy duty machines for felling and bucking. Elliptically fomed, angled oil holes increase the flow speed of the chain oil, delivering optimal lubrication and even longer service life for the guide bar.
