The Tolsen 20069 is a folding Torx key set designed for both home repairs and professional maintenance. This compact kit includes eight keys ranging from T9 to T40, all housed in a folding transformer case that keeps the tools organized and easy to transport. Each key is crafted from heat-treated chrome vanadium steel with a chrome plating for added durability. The tips are CNC-ground to ensure a precise fit into fasteners, while the overall weight of 0.14 kg makes the set light enough to carry in a pocket or small tool bag during a workday.
