The STIHL ROLLOMATIC ES Light guide bar is engineered to be up to 30% lighter compared to the ROLLOMATIC E Super guide bars, making it an excellent choice for reducing operator fatigue. To achieve this weight reduction, long channels are milled out of the center of a solid guide bar, and a thin steel plate of the same high-grade steel is welded over the channels using a precision laser welding process. This innovative design provides the strength of a solid guide bar while significantly lowering weight, especially beneficial on longer bars. The reduced weight not only improves handling and control but also allows chainsaw operators to work longer with less strain. Built for durability, efficiency, and comfort, the ROLLOMATIC ES Light is ideal for demanding cutting applications where performance and reduced fatigue are essential.
