The Tolsen 15138 is a comprehensive 46-piece tool set designed for precision work in tight spaces. At its core is a 1/4" drive ratchet featuring a 72-tooth mechanism for fine adjustments and a two-component ergonomic handle that makes repetitive turning more comfortable. The sockets and handle are crafted from chrome vanadium steel for durability, while the bits are made from S2 steel to resist wear during heavy use. This kit includes 13 metric sockets ranging from 4mm to 14mm and 21 socket bits covering Torx, Phillips, Slot, Pozi, and Hex profiles. To help you reach difficult angles, the set provides a flexible bar, a universal joint, and two extension bars of 50mm and 100mm. You will also find a sliding bar, a screwdriver handle, a 25mm adaptor, and four small hex keys between 1.27mm and 2.5mm. Everything is organized within a blow mould case, ensuring that each piece stays in place and is easy to transport for home repairs or automotive maintenance.
