Best Impact Driver- 20v Cordless Dewalt ,Milwaukee and Black & Decker

Whether you are a professional workman or a DIY enthusiast, you’ll agree that there is one tool you just can’t do without, and that is the drill.  It is simply a must-have, possibly even the first tool you bought as you started out.

However, as you come to scale up to heavier projects, you’ll find that sometimes an ordinary drill just doesn’t cut it. Additionally, you will need something strong and robust with the power to drive through longer screws and denser materials. Well, this is where an impact driver comes in.

Choosing The Best Impact Driver: Cordless  Dewalt, Milwaukee, and Black & Decker For Your Home and Workshop Needs-  Buying Guide

Since an impact driver is a more powerful tool, it is naturally expected to come a bit more expensive than your ordinary drill. Well, before you go spending your fortune on the first flashy piece, it is best you get the gritty details on what an impact driver comprises so you can choose the one that suits you best.

We shall look at some of these common features, as well as some common questions asked by individuals regarding impact drivers

First Of All, What Is An Impact Driver? Why Not Just Use An Ordinary Drill?

Well, as its name suggests, an impact driver is simply a tool designed to drive screws. They are usually fitted with quarter-inch hex bit holders to allow for direct connection with screwdriver bits. So then you might be wondering, isn’t that what an ordinary drill is for?

Well, this is true to some extent. A drill does do the same job, and the two are quite similar in appearance as well. However, much as they look like the same thing to the untrained eye, there are a few differences that make them function independently of each other.

The main difference is that an impact driver is more powerful, which makes it able to deliver more torque than your typical drill. This makes it ideal for large fasteners like coach screws and decking screws. The impact drivers achieve this torque through a rotational hammer mechanism, which automatically kicks in when you encounter larger load conditions.

With this, you get a much more serious edge when dealing with thicker, longer screws that would normally stall a cordless drill. Impact drivers also feature more compact shapes that make them especially easy to handle (especially if you find yourself standing on a ladder).

The only downside to impact drivers is that most of them can only work using their own impact-rated quarter-inch hex bits. This, in turn, limits its capability to just reverse and forward movement. It is therefore important to have an impact driver, as well as, a drill in your arsenal.

What Is An Impact Driver Used For?

As we’ve seen, impact drivers are much more powerful versions of drills. They are mainly designed to help easily drive large fasteners. This includes long, thick screws and lag bolts.

Also, by using impact-rated ¼’’ hex drill bits, you can be able to achieve other basic drilling tasks with an impact driver. Because of its greater power and torque, it has the force to drive larger-sized screws up to 3 times quicker than an ordinary drill. They are also more precise and consequently result in less pressure on your wrist.

Key Factors To Consider When Choosing An Impact Driver

Power: Seamlessly Glide Through The Demanding Tasks!

Perhaps the most important element to an impact driver is its power. Needless to say, the more power the tool has, the faster it will drill in the large screws.

Therefore, if you are a professional constructor or you deal with heavy-duty tasks like fastening nuts and screws in machinery and automobiles, you should definitely opt for a tool with more power.

On the other hand, if you are only using it for home DIY projects, then a model with less power would prove equally effective. Other factors that contribute to the overall efficiency of an impact driver include:

Torque: Where Does The Term Rpm Apply Exactly?

This refers to the measure of the twisting power or rotational force of the impact driver. It is what mainly affects how well it will get the job done. Torque is usually measured in inch-pounds.

In this case, a smaller, low toque impact driver (800 inch-pounds) will do good in a workshop setting. For driving multiple screws, you will need one with more torque of about 2,000inch-pounds or higher.

This will be able to produce a higher quantity of blows (per rpm), which, in turn, produces a greater hammering effect on the surface. Impact drivers with higher torque are therefore best for driving through dense, tough materials, like concrete.

Battery: For A Longer, Uninterrupted Process!

The battery capacity of your driver also has a role to play in performance. Most drivers you’ll find out there use either 18V or 12V batteries.

With 18V batteries, you get more inch-pounds of torque, although they will be heavier. With 12V batteries, on the other hand, you get lower torque, although they are lighter and would, therefore, let you work for longer.

Also, on batteries, you might want to consider the charging time. Most brands will use a lithium-ion battery, while in some, you’ll get various fast charging options. Lithium batteries tend to last longer and will generally provide consistent performance p until their cycle is complete. They are lighter in nature and might cost more.

You might want an impact driver that has fast-charged as it reduces the downtime in case you run out of juice. With this, you get to work for longer while cutting down the time you spend waiting for the battery to charge.

Weight: Bigger Is Not Always Better!

As we’ve seen, impact drivers generally weigh less than ordinary drills. The battery size is what varies, and it can cause a significant increase in your tool’s weight. Therefore, for comfort, you are advised to choose a driver with optimal weight, especially if you plan on using it for extended periods.

In the event that your work required brute force, you might have to use an 18V battery-powered driver. Here, you’ll have to employ more muscle to control and operate it. On the other hand, for DIY purposes, you’ll be better off with a lightweight model.

Design: Is It Ergonomic And Easy To Handle?

You’ll find that most impact drivers have the same appearance. They will often have a rubberized grip and will be lightweight with a compact construction. You will want an impact driver that fits easily into your palm.

A good impact driver feels right to the touch, and also doesn’t get too hot or vibrate too much during use. You will also want one with over-mold to protect it from damage if it falls.

Some Other Essential Features You May Also Want To Consider

Brushless Technology

This kind of technology will be common to most modern impact drivers. Manufacturers especially refer to this because they are more efficient, last longer, and generally perform better than brushed drivers. It is important that you check for smart controls to prevent overheating or overloading, which, in turn, helps increase the longevity of your battery.

LED Lights

Most impact drivers will also feature LED lights beneath the driver’s head. This will help by providing some lighting when working in low lit spaces. LED lights also come in handy in locating your machine if you accidentally drop it.

A Variation Of Speeds

Most models of impact drivers will have up to 3-speed modes. This will let you adjust the tool’s motor speeds depending on the demands of your job. Mostly, they will only need you to squeeze the tool’s trigger tighter.

Reverse Function

With a reverse function, your driver doubles back as both a screw remover and screwdriver. You will find a switch in place that will allow you to switch the direction of the rotation from forwards to backward to let you loosen and drive nuts and screws.

Other Attachments

Some impact drivers will feature adapters that let you use them as a right-angle driver or wrench. You need to look out for any additional attachments like this, which can help increase your tool’s utility.

So How Exactly Does An Impact Driver Work?

An impact driver works much like your ordinary drill. Using rotational force, they are able to drive screws into metal sheets or wood. However, additionally, impact drivers also apply rotational hammering, a mechanism that is considered more effective when driving screws without the risk of stripping the screw’s head off.

With this, they are more precise in the process of screw removal. Because it is likely that the rotational hammering will be loud, you are advised to wear proper hearing protection when operating impact drivers.

How To Use An Impact Driver

First of all, it is important to note that an impact driver does not accept just any bits like a drill does. Instead, it features a collet that only accepts ¼ inch hex shank driver bits. In order to release or insert a bit, you’ll need to pull the collet in a forward motion. That said, using an impact driver comes down to 7 major steps.

  1. Insert the battery – if your driver is cordless, it will require a battery to work. Therefore start by inserting a battery by first, switching it off, then sliding the power pack back into position
  2. Insert the ¼ inch drill bit – next up; you will need to insert the respective ¼ inch bit into the tool’s chuck. Make sure it locks into place.
  3. Set the respective rotation – go ahead and set the tool’s reverse switch. This can either be forward or reverse, depending on what you want to get done.
  4. Set the speed you want – if your model has in place a variable speed feature, you should set a particular speed with respect to your task.
  5. Turn on the tool – switch on the driver.
  6. Squeeze the trigger – finally, to get the chuck to rotate; you’ll need to squeeze the trigger. In some drivers, the harder you squeeze, the faster it will rotate.
  7. After the job is completed, set your impact driver aside and let it cool off. Then, afterward, detach its bits, clean it and store it away.

As mentioned, it is imperative that you invest in a couple of quality ¼ inch hex bits. They come in different varieties that can fit any kind of screw head. With this, you will have the option of using your impact driver as a drill.

Since they work a bit differently and have more power, it might take some time to get used to the feel of an impact driver. They are also louder, so you’ll also need hearing protection gear for long durational use


All in all, impact drivers are the ideal tools for doing any heavy-duty fastening and screw driving. With them, you get to rid yourself of all the drudgery of work. They increase efficiency and speed, and in the end, will help achieve more professional results.

Therefore, before you make your pick, you should keep in mind what you want to use the tool for. Then look at the other features like speed, torque, size, battery, and ease of handling and see what you need to ensure a smoother experience.
