As the name suggests, mechanic tool sets include a wide assortment of tools needed to do automotive or motorcycle repairs or repairs on other common engines, including lawnmowers and chainsaws. But these tool kits also have many applications around the home, particularly in carrying out electrical projects. You typically won’t find hammers, tape measures, or levels in a mechanic tool set; instead, these kits are heavy on sockets, ratchets, hex keys, wrenches, and nut drivers.

We did the research for you, and researched the best mechanic tool sets in a variety of categories, so you can find the set best suited to your needs.

Here, the best mechanic tool sets.

Best Overall: DEWALT DWMT72165 Mechanic Tool Kit and Socket Set

Mechanic Tool Kit and Socket Set

The DEWALT DWMT72165 Mechanic Tool Set and Socket Kit includes 204 pieces with a greater focus on sockets and ratchets than many other kits. This makes it a great choice for anyone looking to quickly establish a complete mechanic tool set, or people who work on parts or projects with a large amount of nuts and bolts of different sizes. The sockets in the tool set include virtually any common size you may need, and are clearly marked so you can easily find what you need when you need it.

The standout part of this set is the primary ratchet that will work with any of the sockets included in the set. The ratchet has a 72-tooth gearing system that gives you precise control over the amount of torque you apply. The body of the ratchet is slim for difficult to reach places and is designed for one hand operation with quick socket changes.

Best Budget: Hi-Spec 67-Piece Auto Mechanics Tool Set

67-Piece Auto Mechanics Tool Set

You won’t get professional quality, but if you just want a starter mechanic tool kit for occasional repairs on your car, motorcycle, lawnmower, or for around the house, use, a low-cost tool set is a perfect way to get the basics at a price that won’t break your budget.

The Hi-Spec 67-Piece Auto Mechanic Tool Set focuses on all the commonly used tools needed for auto repair, including a large selection of sockets, ratchet handle, screwdrivers, pliers,
voltage tester, wrench, hex keys, and earthing lead. It’s perfect to keep in your car for emergencies while on the road, or in the garage for when you are working on your car at your leisure.

If you have a large collection of tools already, this set is also a good option for a smaller, more mobile tool set. Instead of reaching for tools from all corners of your workspace, this one keeps everything in a sturdy case for you to keep at your side as you work. Choose from SAE or metric options.

Best Mixed Tool: Crescent CTK170CMP2 170-Piece General Purpose Tool Set

170-Piece General Purpose Tool Set

One tool set to do it all is the dream of many professionals and DIY enthusiasts alike. While it may just be a dream, the Crescent CTK170CMP2 certainly gets close by offering 170 assorted tools you can use on virtually any project, and in both common SAE and metric sizes. With ratchets, sockets, wrenches, pliers, and more, this is the best choice if you only want one tool set to store.

One of the best features about this set is the storage case. The inside compartments make it easy to organize the tools so each one has a proper, easy-to-reach spot. When closed, the convenient handle also means you can carry this set with you wherever you need on projects that require moving around.

Best Large Set: Craftsman 450-Piece Mechanic Tool Set

450-Piece Mechanic Tool Set

When quantity is important, the more tools a set includes, the better, but that doesn't mean you should skimp on quality. Craftsman’s 450-piece tool set offers one of the most complete and extensive kits available on the market, and it's excellent quality to boot. This is the kind of tool set you should buy if you want to cover all your bases, or be prepared for random, unexpected projects that can come up around your home or in your car.

While 191 sockets, 16 combination wrenches, 40 hex keys, and 187 bits might seem like overkill, it can be smart to have an extensive collection of tools in both SAE and metric sizes. There are plenty of other tools, as well, including ratchets, extension bars, handles, and adapters. And the entire kit packs neatly into an included four-tier organizer box with a handle for easy transport.

Usually, smaller tool kits will leave something out that inevitably becomes important right when you least expect it. Having a large collection of tools like this minimizes the chances of this happening while allowing you to tackle more specialized projects.

Best Starter Set: Stanley STMT73795 Mechanic Tool Set

Mechanic Tool Set

A good starter mechanic tool set should offer you plenty of variety and flexibility to tackle any number of projects. Since small parts come in both SAE and metric measurements, it doesn't hurt to have an assortment of both types of tools as well. The Stanley STMT73795 Mechanic Tool Set offers 210 separate metric/SAE tools and sockets/drivers that will be enough for most screws, nuts, and bolts you may encounter.

All the tools are forged from high strength steel and are ergonomically designed for a comfortable grip. Many of the tools are also designed for quick use. The ratchets can easily switch different sockets and extensions, and reverse direction with a simple thumb flick. Everything is contained in a durable, easy to carry case.

Best Small Set: Stanley STMT71653 Drive Socket Set

145-Piece Mechanic Tool Set

A small mechanic tool kit makes it easier to keep track of the most important or common tools you use regularly. For something small and manageable, the Stanley STMT71653 Drive Socket Set focuses on quality over quantity. With 145 pieces, the set offers some of the most common tools you will need for typical projects around the home and garage. Each tool is made from high quality steel and finished using nickel or black chrome. It's an excellent kit if you only occasionally do simple repairs, or want a second kit you can carry with you in the trunk of your car.

The ratchets of the set include Stanley’s Max-Drive design which increases the amount of torque you can deliver while tightening nuts and fasteners. The design also helps the tool last longer, since it minimizes the amount of contact between the ratchet and the socket while still delivering more torque than other common ratchets.

Final Verdict

The DEWALT DWMT72165 mechanic tool set (view at Amazon) has just about anything you might need to tackle most common car repair issues, as well as other repairs or DIY projects around the home that involve a lot of nuts and bolts of various sizes, and includes a high-quality ratchet that is designed for one-handed use. But if you’re looking for a less expensive set that’s still adequate for basic auto work as well as use around the home, and that includes tool staples such as a hammer, pliers, level, and tape measure, then the GreatNeck GN205 (view at Walmart) fits the bill.

What to Look for in a Mechanic Tool Set

Measurement System

Often, you’ll have to choose between two measurement systems when buying mechanic tools: SAE, which stands for Society of Automotive Engineers, or metric. Metric sockets are measured in millimeters, while SAE sockets are measured in inches. 

Unfortunately, there aren’t precise correlations between these two measurement systems, so consider how you’ll be using the sockets to determine which measurements will best suit your needs; many older American cars use SAE tools, while newer American and most European autos use metric. If possible, you may want to look for a set that includes both types of heads, just to be safe.

Tool Variety

Consider the variety of tools you get with each kit as well as your own experience and level of interest in doing car and other engine repairs. If you’re a DIY novice tackling very simple repairs, a set with fewer than 100 basic pieces will likely suffice. However, if you’re more experienced, you might be better off with a larger set of several hundred pieces covering all the potential issues you are likely to face.

Accessories and Adapters

In addition to standard wrenches, handles, and sockets, some mechanic tool kits come with accessories like breaker bars, torque wrenches, U-joint adapters, socket adapters, and more. Consider whether you’ll need these attachments for the projects you’ll be working on.
