Our take on the Craftsman Cmmt45256 Mechanic's Set

The Craftsman CMMT45256 is a 256-piece mechanic's tool set built around 1/4, 3/8 and 1/2 inch drive ratchets, sockets and accessories in both metric and SAE sizes. It covers the three drive sizes most home and hobby mechanics reach for, so one case handles small interior work and larger suspension or engine fasteners. Compared with smaller starter kits it offers far broader size coverage; compared with pro-grade sets it uses a simpler ratchet design and fewer specialty tools. It suits DIYers and new mechanics who want one organized case rather than buying sockets piecemeal.
