Now with angled oil delivery hole. Unlike the STIHL ROLLOMATIC® E Standard, the STIHL ROLLOMATIC® E Super consists of a solid and particularly rigid bar with a sprocket nose which can be replaced as a whole. Designed for the most demanding professional jobs, it is primarily used on heavy-duty saws for felling and bucking. Available as wide and narrow nose guide bars. If you need assistance with finding the correct chain, please use the Saw Chain Selection Guide Replaceable sprocket nose Sprocket noses are replaceable on STIHL ROLLOMATIC® ES Super guide bars. Unlike some guide bars, the sprocket nose is anchored by three rivets instead of one. Tests at STIHL in Germany show that a bar tip anchored by three rivets could last from two to three times longer than a bar tip anchored by only one rivet – another reason to choose STIHL guide bars.   Note: The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.
