DEWALT DWMT81535 247-Piece Mechanics Tool Set with 72-Tooth Ratchets

Quick-release ratchets with 72 teeth move through a 5-degree arc, helping you turn fasteners where there is little room to swing a handle. That controlled movement is useful for hands-on mechanical work in tighter spaces.

This 247-piece DEWALT set brings sockets, wrenches, hex keys and bits together in one organized case. With SAE and metric measurements, it covers jobs that call for different sizing systems without making you assemble a collection from separate kits.

If you mainly want a small set for occasional fixes, a compact selection may suit that need. For a wider range of mechanical tasks under the hood or around the home, this set combines multiple drive sizes and tool types in one place.

What to know

The set includes 1/4", 3/8" and 1/2" quick-release ratchets, plus standard and deep sockets in all three drive sizes. Socket options include 6-point sockets, while additional components include combination wrenches, hex keys, Torx sockets, specialty bits, nut bits and spark plug sockets. A bit driver, extension bars and adapters round out the selection, giving you different ways to reach and turn fasteners.

The ratchets’ quick-release buttons make it easier to attach and remove sockets as the task changes. For a practical example, you can move from a socket to a bit or wrench while working through a repair, with the case keeping the tools gathered between steps. The full-polish chrome finish is designed for corrosion resistance, and the vinyl anti-slip grip on the multi-driver adds comfort when handling it.

Tips for day-to-day use

Choose the socket or bit that fits the fastener, then match it to the appropriate drive size. The included SAE and metric measurements support work across both sizing systems. When access is restricted, the ratchets’ 5-degree arc can help you make progress with a smaller handle movement. Extensions and adapters provide additional ways to configure the tools for the task.

After use, return the pieces to the durable case and secure it with its metal latches. This keeps the collection together for storage and makes it easier to carry between a workbench, garage or job location.

Practical tips

For routine maintenance or a mechanical repair, start by identifying the fastener size and the access you have. Use the corresponding socket or bit, and select among the 1/4", 3/8" and 1/2" ratchets as appropriate. Deep sockets, extension bars and adapters give you further options for reaching fasteners, while the combination wrenches and hex keys cover other common tool needs within the set.

The broad mix is especially useful when a job involves several fastener types rather than one repeated task. Keeping the set in its case also makes it straightforward to return tools to storage and find them for the next repair.

Practical questions

What drive sizes are included? The set includes quick-release ratchets and sockets for 1/4", 3/8" and 1/2" drives. It also includes both standard and deep sockets.

Does the set cover SAE and metric measurements? Yes. The set is listed with SAE and metric measurements, so you can select the appropriate sizing system for the fastener at hand.

How are the tools stored? They are stored in a durable case with metal latches, providing a place to organize the set and carry it for use elsewhere.

When it makes sense

A solid pick if you want a broad mechanics tool collection rather than a few task-specific pieces. The 247-piece assortment combines multiple ratchet drives, sockets, wrenches, bits and hex keys, while the quick-release ratchets and organized case make the set practical for ongoing mechanical work and repairs.
