Impact drivers have their roots in the impact wrenches used by mechanics. Even so, they have changed a lot, becoming tools that are useful for a variety of purposes besides tightening and loosening car lug nuts.

Some said the name “impact driver” was just a marketing ploy, created to try and differentiate these tools from the pneumatic impact wrenches used by mechanics. However, there are more differences between the two than you might think.

While the largest and most pneumatic are essentially the same, there is no way to call a cordless impact wrench for lightweight impact wrench services. Besides not being that powerful, it was designed to be used differently.

What is an Impact Driver?

To the untrained eye, an impact driver may look like your regular cordless drill. However, a drill and impact driver specialise in two different things.

An impact driver was made to do one thing really well, and that is to screw and unscrew screws as well as bolts as fast as possible without much effort from you!

As well as impact drivers, there are also impact wrenches, the main difference between the two is that an impact wrench is designed for working with heavy duty nuts and bolts only, and produces very high torque, more than what is required for screws or general bolts. If you put up scaffolding or work on a construction site where you are working with heavy duty bolts, an impact wrench will be a better tool for the job.

The reason why this power tool is so efficient at screwing and unscrewing is because it delivers a lot more torque than a regular drill or electric screwdriver.

Your average drill delivers anywhere from 25Nm – 60Nm torque, whereas an average impact driver delivers 120Nm to 220Nm. The amount torque you can extract depends upon the model.

This tool is excellent for driving long screws into timber with one hand and no wrist strain, that’s how effortless this tool makes driving screws.

How Does an Impact Driver Work?

Impact drivers work differently to electric screwdrivers and drills. Impact drivers use rotational hammering function. The best way to explain it is using the following example:

Imagine you’re trying to loosen the lug nuts on your car wheels. You are using a large wrench to try and twist the bolt off, but it has been screwed on so tightly that it won’t budge.

It needs more torque to be taken off. The solution is to hit the end of the wrench with a hammer as hard as you can and as many times as you can until it loosens.

Impact driver does the same thing, if it encounters any resistance when trying to unscrew or even screw for that matter. It has an internal mechanism that hits the rotational part of the driver up to 50 times a second in some impact drivers. This helps it to produce enough torque to loosen or drive in any stubborn screws or bolts.

This tool doesn’t rely purely on the spinning mechanism to screw or unscrew, it has a hammering function which kicks in when things get tough.

This hammering function also greatly reduces the risk of stripping the screw head. When you only have high RPM at your disposal, the screwdriver bit starts to slip and eventually strip the screw head. High RPM only has the ability to spin fast without much torque behind it to loosen screws without stripping them

When you have a high torque hammering function, it’s not spinning uncontrollably but being hit with force multiple times and this greatly reduces the chances of stripping a screw head.

Can You Use an Impact Driver as a Drill?

Yes, you can if you have HEX drill bits. This power tool is absolutely fine for general drilling here and there, however, it is not ideal for any precision drilling or drilling into masonry.

One of the issues with this tool when it comes to drilling is that there is a play in the HEX connector.

This can cause the drill bit to wobble when drilling, which can cause the hole you are drilling to be a little bit bigger than required, if you are trying to drill a 6mm diameter hole, it could end up being 7mm or 8mm diameter hole. That’s why it is not recommended to use this tool for precision drilling.

When screwing into wood, some jobs require pilot holes, and you can use this tool for that a well as other drilling that does not require precision.

What’s The Difference Between a Hammer Drill and Impact Driver?

Another common question is, what is the difference between an impact driver, and hammer drill?

Each power tool specialises in different things and below we will have a look…

As we already mentioned, when it comes to efficient screwing and unscrewing, the impact driver is king due to its enormous amounts of torque and rotational hammering function, it is built to fasten and unfasten.

Hammer drills specialise in drilling into masonry. Hammer drills also have a hammering function, but very different to what you’ll find in an impact driver.

When you are drilling into masonry, not only does this type of drill have a high RPM, it also has an internal mechanism hitting the chuck to help eat away at the masonry you are drilling in to.

Think of it like this: imagine you are using a regular drill and you encounter some resistance in brickwork, whilst you are drilling you get a friend to hit the end of the drill with a hammer. This helps to add more force and helps to drill through any stubborn masonry.

Is it Worth Getting an Impact Driver?

I guess the final question on your mind is, do you really need an impact driver? It all comes down to the type of jobs you are doing, different tools for different jobs.

If you’re putting together decking or putting together any other large structures that are mainly made of wood, then absolutely yes! Because you will be driving a lot of long screws and you want to do it in the quickest time possible with the least amount of effort.

If you are also finding yourself needing to remove a lot of stubborn screws or bolts, than there is only one tool for the job, an impact driver.

If you do a lot of drilling, and are thinking of replacing your cordless drill with an impact driver, then you absolutely do not need an impact driver and would be replacing it with the wrong tool.

However, a lot of us just like to have a selection of tools, in case we need them, and if you’re one of these people like me, then go ahead and get yourself one, above you will reviews of some of the best cheap impact drivers available.

​Finding the Best Impact Driver

The main purpose of an impact driver is to drive screws — with speed, power, and accuracy; and it is equally versatile for driving nuts and bolts, and for drilling holes in wood, plastic, or metal. Light weight and compact size make the best impact driver comfortable to handle for repetitive work and ideal for working in tight spaces.

Most impact drivers are cordless, powered by rechargeable batteries, which means added convenience for the craftsman. Batteries are available in a variety of sizes so that you can adjust the mix of power, size, weight, and run time, to find the best impact driver to match your personal or job needs.

The unique designs of the best impact drivers sense when more force is needed, and adds hammering action to rotational force to apply the right amount of power. This is highly effective for loosening rusted or over-tightened nuts, driving large lag screws, drilling holes in hardwood, and for many other difficult jobs.

Why Should You ​Select Your Best Impact Driver Carefully?

To identify the best impact driver, you need to consider your personal preferences, your job requirements for the range of projects you expect to be working on, and compatibility with your other tools to optimize your overall tool kit.

​The best impact driver package for you requires: the tool itself, one or more rechargeable batteries, a battery charger, a suitable array of driver bits and accessories, and a container you can carry to the job. You can mix and match to create a package that optimizes performance and cost to meet your specific work needs.

You may already have several other tools of a brand that you like, and may already have batteries and chargers that are compatible for your new impact driver, which could reduce your cost to acquire a functional package. Or, you may prefer to buy all-new batteries separately. Or, you may want to buy a “kit” that includes all the components needed. Having several batteries of different power capacities will enable you to pick the ​best impact driver combination for power, weight, size, and run time for the task at hand.

The best impact driver bits are made specialized high strength steel with a hex-shaped shank and come in a wide variety of sizes and shapes for driving and drilling. You may only need a few individual bits, or small sets of a few sizes, or a large set of driver bits and accessories to cover any job situation.

It is essential to consider a few decision-making factors before purchasing so that you select the best impact driver to suit your needs.

Factors To Consider Before Buying ​The Best Impact Driver

Here are a few decision-making factors you should consider to be sure you select the best impact driver for your personal and job-related needs.

​* Battery not included.    Swipe Left-Right to scroll horizontally.

Torque is the measure of an impact driver’s turning force, expressed in units of “inch-pounds.” In simpler words, it is the power of a tool to drive a screw into a material. ​

Battery Voltage is related to torque and ​run time. ​For single-speed drivers, higher voltage values ​produce increased ​applied torque (for heavy-duty jobs) while lower voltage batteries, in the same driver, produce ​less torque (for delicate high-accuracy tasks).

Maximum Rotary Speed​, expressed as revolutions per minute (RPM), ​is an indicator of potential productivity and power — the ability to do big jobs fast.

Maximum Impacts per Minute (IPM) represent the additional potential power of the impact driver design compared to conventional drills.

Typical Price Range ​is an approximation of prices from in-store and online retailers, including Amazon. Prices, and bargains are constantly changing so it is important to use a reliable source that is consistently known to sell at the lower end of the spectrum.​​​

Other F​actors ​- ​The Best Impact Drivers have these features:

  • ​Reverse switches and variable speed trigger function
  • LED lights focused on the work area
  • Available limited warranties in the 1-3 year range
