A cordless driver/drill is normally one of the first power tools most people buy, thanks to its tremendous versatility. A solid driver or drill makes several tasks easier, from building decks and screwing down plywood to installing tile backer boards and many other jobs that need driving screws into wood. So, we've looked at and rounded up a couple of standout options on the market to help you find the best impact driver for your home or workshop.
Which Brand Impact Driver Is The Best?
What's an Impact Driver?
An impact driver looks similar to a power drill and is also a handheld tool mainly used to drive screws. However, an impact driver has significantly more rotational force than a power drill, extremely quick bursts of up to 50 times per second. This creates an extremely powerful torque that can drive even large screws and various fasteners into hard materials easily and quickly.
Impact drivers also don't have a chuck; instead, they have a quick-release shank that fits all 1/4-inch hex driver bits. Therefore, impact drivers are not only nifty for simple around-the-house tasks, but they're also equally capable when you're facing projects that involve lots of wood screws, like building a deck, erecting a fence or even assembling a child's swing set. The power, lighter weight and ease of use make an impact driver both an effective and efficient power tool.
How Does it Work?
The typical drivers apply torque on the load at a steady rate. Conversely, impact drivers produce exceedingly rapid bursts of impact-somewhat similar to a hammer blow to generate their torque, creating an incredibly powerful turning force. So how does it all happen?
An impact driver is (in part) made up of a spring, a "hammer", and an anvil. When the motor spins the shaft, it compresses the string and then releases with immense force, striking the hammer and which hits the anvil. The entire process happens very rapidly, usually over 50 times per second, which adds bursts of impact to the torque.

It produces a maximum torque of 2000 inch-pounds, a tremendous 4350 ipm and a speed of 3100 rpm, giving you tremendous power for all your drilling duties.
More so, it's a brushless impact driver, hence more power and longer battery run-time so that you can keep going on your project. The 18-volt batteries, also used on more than 80+ power tools in the company's lineup, do a great job of powering this powerful and fast impact driver. In addition, the 1/4-inch quick-connect hexagonal shank holds most driver bits firmly and securely, while a magnetic tray holder offers the space to keep spare bits when you're not using them.
Factors to Consider in the Best Impact Driver
1. Battery Power
While you can always find corded impact drivers, the cordless impact driver is more common, thanks to its unlimited radius of use. That means easily working your way down a series of screws when dealing with a large project. Generally, cordless impact drivers run on batteries with three common power capacities; 12-volt, 18-volt and 20-volt.
12V impact drivers are compact and lightweight, hence easier to carry around while your work. They pack enough power to drive your average-sized screws into soft to mid-weight wood, making them an excellent choice if you'll only use the tool for small and light projects around the house, say putting together a swing set.
18V impact drivers are a bit larger and heavier, certainly with more power, making them more suited for projects that involve large screws and hardwood. That means an 18V impact driver is a great versatile choice for people who are serious about DIY and need that extra bump-up in power.
20V impact drivers are the big guns; heavy-duty tools built to drive even oversized screws into the hardest wood repeatedly. This makes them ideal for contractors or DIYers working on exceptionally large projects, such as building a deck or adding a room to the house.
2. Torque & Impact
Impact drivers are primarily all about torque, which represents the tool's turning power in inch-pounds. Typically, the more the battery power, the higher the torque, explaining why 18V and 20V impact drivers handle harder wood with more ease than 12V drivers.
A 12V impact driver produces around 800 inch-pounds of torque, while a 20V counterpart can deliver a robust 2,000 lb-ft. Therefore, the 12V models are more suited to typical house and DIY tasks, while the more powerful 20V models are ideal for heavy-duty projects.
You'll also want to consider the rate at which the tool delivers an additional "blow" of power when in use, usually measured in impacts per minute (ipm). Lower-powered impact drivers generally produced around 2,000 ipm, while the more powerful ones are capable of up to 3,700 ipm. It's worth noting that manufacturers indicate the tool's "no-load" ipm, meaning the impact produced when it's running in the air and not, in fact, driving a screw.
The rotations per minute (rpm) refers to how fast the driver bit turns. Naturally, the faster the bit turns, the quicker the job gets done. But it's important to consider that turning too fast can strip screws or cause damage to the wood.
You'll also find the speed tends to increase as torque increases. That said, most higher-end impact drivers nowadays come with multiple rpm settings, ranging from 600-800 rpm on the lowest settings, 1800-2000 rpm on mid settings and 3000+ rpm on the highest settings. The number stated is equally the "no-load" rpm, representing the speed when the driver is running in the air and not driving a screw.
Generally, impact drivers are small and light, allowing you to use them over an extended period without causing hand or arm fatigue. It becomes especially crucial when you're inserting screws overhead. The smaller the impact driver, the less cumbersome it is to use and the more it fits into tight spots that would be inaccessible with a regular drill.
It's also important to ensure that the tool fits in your hand firmly. This means having a comfortable and secure rubber overmold to ensure that you get maximum grip when working.
6. Noise Level
In recent years, hydraulic impact drivers have become more affordable. Therefore, we don't have to contend with these tools being loud as just the way it is. Now you can find quieter options that are handy in occupied spaces such as office buildings and schools.
Frequently Asked Questions (FAQs) on Impact Drivers
1. Do impact drivers typically require special bits?
Yes. Impact driver bits are built to withstand immense torque. As such, they are made of fairly more flexible metal than regular bits. Furthermore, impact driver bits have slightly narrower shafts with hexagonal ends, unlike the rounded ends in most regular bits.
As such, while you can arguably use impact driver bits with a regular drill, it is UNSAFE to use regular bits with an impact driver.
2. Do impact drivers come with torque settings?
No. Unfortunately, impact drivers come with preset torque. Therefore, they're most all-or-nothing tools that are best saved for projects that really need substantial force to drive screws through hard materials, or tasks where the high driving speed is necessary.
