Criteria Used for Evaluation

Power Source

A power tool should be just that, powerful. One of the deciding factors besides the battery is the motor that the power tool comes with. You want to check the descriptions and check for the power output and the torque per inch amount- this determines what the motor can deliver and what it is capable of. The newer, high-quality models now boast a brushless motor design, which delivers a smarter, higher power that adapts to the job at hand or resistance level. This can often come with a higher cost for those with a brushless motor, but it may be worth it because it takes all the guesswork and manual labor out of application.

Battery Life

This is especially important to consider when purchasing power tools (if they are cordless). The battery power and battery life will determine how powerful your tool is, which helps determine what you will be using it for. You should always look for lithium ion batteries, which are two times more powerful than standard batteries. Most of the high-quality power tools available on the market today come with lithium ion batteries, and you should be wary of purchasing one that does not have lithium ion batteries. This is because if you are purchasing a power tool, you want it to be working at full speed and force, and often times standard batteries, if they die out, will lower the amount of power of the tool. This causes user fatigue and a longer time for you to get your job done. The standard type of batteries are usually nickel-cadmium, and it is worth it to spend the few extra dollars in purchasing a power tool that supports lithium ion batteries. The battery will also determine the volts and amp-hours, which we will explain below.

Weight

You always want to consider a power tool that is not only powerful but also compact and lightweight enough to get your job completed with ease. You have to consider the amount of time that you’ll be spending on each project or job, and most will take long hours, so you definitely want a portable, lightweight, and ergonomically friendly tool that can help you get your task done. You may be confined to small, tight, and cramped conditions where you have to crawl under or maneuver your body to finish the application. There are tools that are specifically designed in a 90 degree handle fashion so it makes head on applications a lot easier. For situations that require you to be in a small, tight space, a portable, cordless, and smaller device may be better for your job

Bottom Line

Having gone through this comprehensive list, you may have noticed that there were certain toolkits with 4 tools or 9 tools. Some even come with one power tool, and the number of tools you need will depend on what you expect the scope of your work will be. There are many uses for circular saws and multi-tools for maintenance work around the house that you may find yourself in need for in the future. By purchasing the ones with multiple tools, you may find that you are saving yourself a few hundred dollars later in the future.

It's all about power

If you're going to get a combo tool kit like the ones you see here there is one over-riding principle that you have to keep in mind. You're going to need a lot of power so take a look at your batteries and make sure they're going to not only be able to last but also that they have the power to get the job done. There's nothing more frustrating than working with a battery powered drill or saw and losing power halfway through the project. It's the one huge drawback on all of these portable lithium battery sets so make sure you're getting one of our products that lists long battery life as one of its pluses. You won't be disappointed.

Frequently Asked Questions

q: What makes a power tool a power tool?

a:

Power tools are devices or mechanisms that are powered by an alternate power source, such as a battery or through the voltage through the power source in your home. These are called power tools because they are powered by additional sources other than our human hands, and aid us in a variety of needs that would take massive amounts of time and energy if we were to do otherwise. Most power tools are electric or battery based, but some also come in gas or solar power form. The actual power tool at hand will be specific to certain tasks and needs and can be used for a variety of different places, like apartments, homes, construction sites, reconstruction, etc.

q: What are all the different type of power tools and their specific uses?

a:

This is probably the question to most consider to see what it is you really need. We’ll take you through the comprehensive list of what the most popular power tools are and what they are commonly used for.

Air compressor- an air compressor transforms electric or gas power into compressed or pressurized energy air. The longer you use an air compressor, the more it stores the energy into energy. These are used in a number of different situations, like spray painting, auto repairs, filling tires, etc. Generally, these are used for situations where you need pressurized air that you aren’t able to provide by hand.

Angle grinders, also known as disc grinders, are handheld, portable power tools that are used to grind, saw, or cut through and polish even the toughest of materials (think even steel). These are often used to smooth out rough edges and are convenient because of the edge that allows them to fit into little spaces.

Circular saws have been included periodically throughout some of the combo kits on this list for their versatile use. These are the most common type of power tools and can be found in the power kits throughout most garages. These have sharp, abrasive edges and are used to cut through objects in a circular pattern. These are commonly used to make straight lines and cuts through objects and can be cut through plastic, wood, masonry, and even metal. These can come in cordless or corded options.  

A disc sander can be used as an electronic portable sandpapering device. All you need to do is replace the sandpaper mount and you can use it to soften materials in any form. You are also able to have greater control over straightening surfaces and rounding out edges.

Drills are the most common type of power tool and can be found throughout most homes. They provide a variety of uses and often come in a drill/driver combo form that allows for drilling and driving. They often come in cordless or corded drills and often come with a cutting or driving tool attached. You can use these for a wide variety of DIY home projects, like hanging into drywall or putting together types of furniture. Anything that requires putting a hole or drilling screws- the possibilities for the power drill are endless (they are also included in each of these power kits).

A hammer drill or rotary hammer is also quite common- they are used to rapidly hammer using a rotary thrust, which can aid in destroying material or drilling holes faster. They use a rapid “in and out” motion and mimic a demolition hammer function, at a much smaller size.

Impact drivers can also be found in most comprehensive power tool kits. They are used to provide force, or impact, to the project at hand that can’t be achieved manually. It provides a downward and rotary impact and are typically used to loosen bolts or screws that are too tight, and give more control than the standard hammer drill.

An oscillating or multi-tool is one of the most versatile tools that are available. They are versatile because they have the ability to change attachments. The interchangeable attachments can be used for sawing, cutting, polishing, grinding, and many more. If you are thinking of purchasing a multi-tool, look for ones that come with a variety of attachments, so you can get many uses and functions out of this one tool.

A power screwdriver works as a screwdriver but in a more quicker and powerful manner. Although they are designed to be a little slower than your standard power drill, they have powerful screw-driving capabilities and have more torque than drills. This gives you the ability to screw or drill holes without any pre-drilling work

Reciprocating saws are also commonly shown in the combo kits on this list. These use a push/pull method to cutting or sawing and are also abbreviated as recip saws. The blade is often large and has jagged tooths, so it resembles a jigsaw and is often longer to handle more vertical, straight surfaces. These come in variable speeds, giving you more control over your project.

q: Are cordless tools better than corded?

a:

There are many pros and cons to both, which is why it is hard to say if one is “better” than the other. Cordless tools are more common because of their portability and ability to be used anywhere. They are often designed to be more lightweight and compact because you can move them into hard to reach places, and can be stored and put away easily. The drawback is that they usually have a limited range of power and run on the battery capabilities. Corded power tools limit you to being near a power outlet, but since they are being tethered to your home power source, have a constant state of solid power and will be resistant to power fading from battery usage. Most power tools that are cordless do come in lithium-ion batteries nowadays, which can be just as powerful as corded power tools.

q: What is the difference between amp hours and voltage?

a:

We said we’d go over this in our criteria section above, so we’ll outline the difference right now. Amp hours is essentially how long the device can run in relation to how much you’re using. You can remember this easily because of the “hours” in “amp hours.” This refers to the amount of voltage that the cordless drill can deliver in an hour. You want to look for this in relation to the battery pack. A 2.0-ampere-hour battery pack can give twice the amount of usage for a power tool that uses 1.0-ampere hour. On the other hand, voltage refers to the amount of power that the battery allows for the power tool to provide. The two work hand in hand to deliver the most amount of power in x amount of time. If you have heavy-duty construction work, look for high amp-hours plus high voltage, which will give you the maximum amount of power you need before your battery dies. Usually, the higher the amp hours and voltage, the more expensive the product will be, as is expected.
