CRAFTSMAN 57 Piece Mechanics Tool Set (CMMT99447): Your Go-To Home and Auto Workshop Kit

If you’re building or upgrading your home tool collection, the CRAFTSMAN 57 Piece Mechanics Tool Set (CMMT99447) stands out for its blend of durability, versatility, and value. We’ve taken this kit into our own garage, tested every socket and driver, and put it through countless repair and maintenance tasks. Here’s what we discovered.

Gear Up with Everything You Need

This 57-piece set arrives neatly organized in a sturdy, all-steel case. From ¼” to ¾” drive sockets and ratchets to a precision bit driver and a full assortment of hex and Torx bits, you’ll find the tools necessary for automotive repair, furniture assembly, appliance maintenance, and more.

Key Features That Make a Difference

1. Heavy-Duty Storage Case

The deep-drawn, corrosion-resistant case keeps each piece secured in its own molded slot. No more digging through loose sockets or misplacing your extensions.

2. Full-Polish Chrome Finish

Every ratchet, socket, and wrench sports a polished chrome surface that resists rust and wipes clean with a quick swipe of a rag. Even after exposure to grime and moisture, they maintain that “just out of the box” shine.

3. Dual 72-Tooth Quick-Release Ratchets

Whether you’re working in tight engine bays or assembling lawn equipment, the 5° arc swing allows you to make fast progress in cramped quarters. We loved the smooth, positive engagement and quick-release button that drops sockets instantly.

4. Comprehensive Bit Selection

From Phillips and slotted to hex and security Torx bits, the included bit driver and 20 bits cover most fastening applications. We used them to swap out door hinges and tighten shelf brackets with zero slipping or rounding.

Why the CMMT99447 Is a Must-Have

• Perfect for DIYers and weekend warriors seeking an all-in-one mechanics kit
• Compact yet comprehensive—covers 95% of common repair needs
• Lifetime warranty from a trusted brand—CRAFTSMAN stands behind its tools

Putting It to the Test

Real-World Repair Scenarios

We tackled brake-pad swaps, oil-filter changes, bicycle tune-ups, and even assembled a backyard playset. Across all tasks, the ratchets never slipped, the sockets stayed seated, and the bits handled repetitive torque without wear.

Ergonomics and Ease of Use

The ratchet handles have just the right balance of knurling and grip—enough friction to prevent slips but not so aggressive as to chafe your palms during extended jobs. Swapping between metric and SAE sockets is hassle-free thanks to the clear stencil etched into each rail.
