20-Piece 1/4-Inch Drive Set
The Craftsman CMMT12108 provides a 20-piece mechanics tool set built around a 1/4-inch drive format. Alloy steel construction with a full polish chrome finish delivers corrosion resistance for workshop durability. The kit includes a comprehensive selection of sockets and drive accessories suited for general fastening tasks. It is not intended for buyers who require larger drive sizes or impact-rated sockets.
90-Tooth Ratchet With 5-Degree Arc
The included ratchet uses a 90-tooth mechanism that produces a 5 degree arc swing for precise movement in confined areas. Its low-profile head is up to 25% thinner than the CMMT81747 model, improving access where clearance is limited. Sustained use benefits from the fine-tooth engagement that reduces the effort needed to reposition the tool. The design does not suit applications demanding high-torque impact performance.
VersaStack Compatible Storage
The set ships in a VersaStack compatible case that allows flexible, modular storage combinations based on individual workflow needs. This system keeps the 20 pieces organised and portable across job sites or workshop drawers. Compatibility is limited to the VersaStack ecosystem, so users invested in other modular platforms cannot integrate the case directly. No additional storage hardware is included beyond the supplied container.
