Festool invented the guide rail (track system) more than 40 years ago to enhance power tool precision for the most demanding applications. They are available in eight different lengths, ensuring precision cuts for a variety of materials. A multitude of accessories are also available, to suit your specific application, and the guide rail system can be used with or without the MFT. Key advantages of the guide rail system include the elimination of laborious measurement and set-up, rework and wasted material, among others. Each guide rail is equipped with a patented splinterguard that accurately defines the cut line and can be used with plunge cut saws, also known as track saws.
