The Tolsen 15145 is a comprehensive 94-piece industrial socket set designed to handle a wide range of mechanical tasks. It features two distinct drive sizes, 1/4" and 1/2", each paired with a 72-tooth ratchet handle featuring a two-component grip for a more comfortable hold during repetitive use. The sockets and bars are crafted from chrome vanadium steel, while the bits are made from S2 steel to ensure durability under pressure. For larger fasteners, the 1/2" drive section includes 18 standard metric sockets ranging from 10mm to 32mm, four deep sockets, and specialized spark plug sockets in 16mm and 21mm. You can reach awkward angles using the universal joint and two extension bars of 125mm and 250mm. The 1/4" drive set provides 13 standard and 8 deep metric sockets, complemented by a flexible bar, a sliding bar, and a variety of S2 socket bits including Torx, Hex, and Phillips heads. To further expand its utility, the kit includes 15 additional chrome vanadium bits and three small hex keys. Everything is organized within a sturdy blow mould case, making it easy to transport the set to a job site or keep it tidy in a home garage. This collection is well-suited for mechanics and DIY enthusiasts who need a versatile array of tools for automotive repair and general assembly.
