Why Buy an Impact Driver?
Unlike drill drivers, an impact driver has a specific use. Drill drivers drill holes in a variety of materials and drive screws and fixings. An impact driver has more torque and delivers a more significant force when driving screws into tougher surfaces.
If you work in confined spaces, the short length of the impact driver will suit you. It typically has a 0.25-inch hex chuck, designed to take specialist drill and driver bits, but you can get larger chucks that cater to more robust jobs.
The hex chuck ensures that there is no slippage when the impact driver is under pressure, which adds to the power this little tool brings.
They speed up labor-intensive jobs like laying flooring, decking and fencing. Also, if you have rusted lug bolts that need removing, an impact driver is the ideal tool. This makes them handy for repair shops and garages.
What Size Impact Driver Do I Need?
The task at hand dictates the size of the impact driver you need. For general work like driving smaller screws, a 0.25 or 0.38-inch hex chuck will suffice. These are probably the most common size of chuck in use and better suited to general duties.
You should consider an impact driver with a 0.50-inch hex chuck for larger tasks with more demanding bolts and nuts. These larger tools can handle jobs that require more torque. However, they would strip a standard size bolt or screw because they deliver too much torque.
How Do I Choose an Impact Driver?
Think Torque
First and foremost, impact drivers are about torque. They deliver a high amount of power to drive screws and fixings into super-tough materials. You need torque to achieve this. It is the one main advantage impact drivers have over standard drills.
Blows Per Minute
The blows per minute of an impact driver is important because this is how the impact is measured. The best impact drivers combine high BPM with fast revolutions per minute (RPM) for the most impact.
Versatility
Impact drivers are not just for driving screws. They can bore large holes in robust material and they can drive lag screws thanks to their specialist hex-shaped chuck, making them excellent drills.
Voltage
The vast majority of impact drivers are cordless, but you can get a few models with power cords. However, they are few and far between. With cordless power tools, you will quickly learn that voltage equals power.
Most impact drivers have a voltage that ranges from 10.8 to 20 volts. By far, the most common in the States is the 20V variety.
Remember
Brushless Motors
Brushless motors are more expensive than brushed varieties, but if you are looking for a tool that requires minimum maintenance and delivers a more efficient use of the power, a brushless motor is a must-have.
Quick Note
One-Handed Driving
Thanks to their size and high torque, you can deliver all that power using one hand. Unlike a drill driver, that requires two hands to stabilize the tool when drilling or driving through hard material, impact drivers are lighter and smaller.
Hex Socket Size
Hex chuck sizes vary on impact drivers. They come in three main dimensions, namely, 0.25 inches, 0.38 inches and 0.50 inches. The first two are the most common, and are the size found on general-duty impact drivers.
The largest size is for more demanding tasks like working on production lines and auto repair shops, where you need all the impact you can get.
Multiple Mode Settings
Older impact drivers were brute tools, known for their lack of finesse. Newer models have speed settings and impact modes to cater to different scenarios. These innovations help to mitigate the absence of any form of a clutch.
Some impact drivers even have dedicated settings, designed for deck screws, to make specific tasks more manageable.
The Best Impact Drivers of 2021
Channeling your way through the maze of impact drivers can be confusing, so we hand-picked 7 of the best makes and models on the market so you can make an informed choice.
1. Metabo HPT 18V Impact Driver
Metabo is the new name for Hitachi power tools. This tool has 1,832 in.lbs of turning torque and generates 4,000 blows per minute.
If you couple that with the 2,900 RPM, you have a heavy-duty impact driver to rival any tool on the market.
It also has a battery charge indicator, a light and a 4-stage electronic speed switch.
Why We Love It
4-Stage Speed Switch

Triple Hammer Action
Introducing the third anvil increases the BPM and the torque and decreases the vibration of the tool.
Lifetime Tool Warranty
You can’t ask for better peace of mind than a lifetime tool warranty. The batteries are guaranteed for 2 years.
Keep In Mind
Price
This impact driver is expensive, considering it doesn’t even come with the batteries included in the price.
Batteries Required
You would need to buy two batteries and a charger for this tool, and that will set you back almost as much as the impact driver itself.

7. Bosch PS21-2A 12V Pocket Driver Kit
Okay, this is the compact category, so we thought it was apt that this 12V impact driver is called a “pocket driver.” It offers the shortest length of any driver at 5.6 inches, which makes it ideal for small spaces.
And because it is small doesn’t mean it is weak. It still offers 265 inch-pound-force of torque, meaning it can drive screws through wood and 22-gauge metal. It also has a variable speed trigger to help you control the rate of the driver.
Why We Love It
Adjustable Clutch
It has a 20+1 adjustable clutch to help you set the torque level for different materials. The RPM ranges from 350 to 1,300.

Frequently Asked Questions
Can I Use an Impact Driver for Screws?
Yes, yes and yes again. Impact drivers love driving screws. Make sure you have the right size hex shank because if you oversize it, you run the risk of stripping the screw or worse still, snapping it.
Impact drivers are commonly used for laying decks and driving deck screws, as well as lag screws that suit the hex-shaped attachments associated with impact drivers.
Are Brushless Impact Drivers Better?
100 percent yes. Brushless motors are more efficient and deliver a better battery life, but they are more expensive to buy. That said, almost all impact drivers are cordless. A brushless motor increases the runtime of batteries by nearly 50 percent, which is the difference between getting the job done and failing because your battery ran out of juice.
Brushless motors also require less maintenance and are more reliable. You certainly don’t need to replace brushes as you do on a brushed motor.
Does an Impact Driver Need Special Bits?
The chuck is hex-shaped, unlike with standard drills that employ a universal chuck with three grippers to hold the bit in place. The hex shape means that your impact driver will only accept bits that correspond with this shape.
The advantage of having a hex-shank is that changing the bits is easy, and they will not slip when placed under extreme pressure.
Less Torque, More Action
Hopefully, you now have a clearer idea about impact drivers and what they can do. They are not a replacement for your standard drill driver, but they do give you that extra punch when it’s needed.
And if you like to work on your car on the weekends, an impact driver is going to make your life so much easier.
