57-Piece Mechanics Tool Set

The Craftsman CMMT99447 delivers a comprehensive 57-piece mechanics tool set for home and automotive tasks. It combines sockets, ratchet, screwdrivers, hammer, pliers, hex keys and specialty bits in one durable blow-mold case. The set suits DIYers and professionals needing a portable, all-in-one hand tool collection.

Low-Profile 72-Tooth Ratchet

The included ratchet features a head up to 25% thinner than the CMMT81747 for access in tight spaces. Its 72-tooth mechanism provides a 5-degree arc swing for efficient fastening where clearance is limited. This design supports work in confined engine bays or crowded workbenches without sacrificing torque.

Mixed Drive and Hand Tools

The kit centres on 1/4-inch drive mechanics tools supplemented by mixed hand tools for broader utility. Buyers needing larger drive sizes or specialised automotive sockets will find those absent. The set covers general fastening and light repair but does not replace a full professional socket system.

Questions about this item

Which version of the Craftsman 57-piece mechanics tool set should I choose?

The set is offered as a single 57-piece configuration under model CMMT99447; there are no alternative piece counts or drive sizes listed for this SKU.

What does the 72-tooth ratchet with a 5-degree arc swing mean when I am working in a tight engine bay?

The fine-tooth mechanism advances the fastener with only a 5-degree arc swing, so you can turn bolts where a standard ratchet lacks room to move.

How does the low-profile ratchet head compare to the earlier CMMT81747 model in practice?

The head is up to 25% thinner than the CMMT81747, letting the ratchet reach fasteners in shallower recesses that the older design cannot clear.
