Impact Driver Buying Guide

Best Tool-Only: Ryobi ONE+ 3-Speed Impact Driver

It may come surprisingly that some manufacturers leave them out when many impact drivers come with a battery. These tool-only choices are for consumers who already have the company’s interchangeable batteries for other power tools and need the device itself. As a result, a battery-less impact chauffeur is the best way to save cash on something you currently have.

When it comes to getting things attached safely, the Ryobi ONE+ is all about efficiency and speed. Utilizing Ryobi’s popular 18-volt batteries that power the business 80+ power tool line, the best impact driver can deal with most fastening jobs with ease. It has an optimum of 2,000 inch-pounds of torque and a top speed of 3,100 rpm. The 1/4- inch quick-connect hex shank holds most driver bits safely, while a magnetic tray holder supplies a space to keep spare bits when not in usage. So it is one of the best tools in this impact driver buying guide.

Best Compact-Combo Kit: DEWALT DCK240C2 20-Volt Max Combo Kit

The DEWALT DCK240C2 combination kit gives you the best of DEWALT’s power tool line. With a drill and impact driver, the set will cover most fastening needs you might have at home or out on the job website. Both devices offer a comfortable grip because of the ergonomically developed deals and are compatible with most 1/4- inch hex shanks. The included charger will charge the 20-volt battery in a couple of hours also.

Both tools are relatively compact, making them ideal for circumstances where fasteners are challenging to reach, or you don’t have a great deal of space to maneuver. They consisted of an impact driver that offers approximately 1,700 inch-pounds of torque and two-speed settings. The set includes two 20-volt batteries, in addition to a charger and handy carrying bag.

What to Search for in an Impact Driver

Battery Power

This is a vital point of this best impact driver buying guide you should know about. While there are corded impact drivers, they have seldom used in the DIY setting. Being without a cord suggests you can quickly work your way down a row of screws while tackling a big job, such as putting up a fence or developing a deck. Cordless impact drivers run batteries– normally lithium-ion– and the three standard power capacities are 12-volt, 18-volt, and 20-volt.

Twelve-volt impact drivers are lightweight and compact, making them easy to carry along while you work. They have adequate power to drive average-sized screws into soft to mid-weight wood, making them a great choice if you expect to use the tool for little tasks around your house, such as assembling a swing set.

Eighteen-volt impact drivers are a little bigger and heavier but likewise have more power, making them the better choice for tasks that require big screws or involve complicated wood. You’ll find an 18-volt impact chauffeur is the most versatile option if you take DIY seriously.

Twenty-volt impact drivers are the huge boys; these heavy-duty tools don’t hesitate at driving even oversize screws into the most complicated wood over and over again. While it’s usually professionals that choose these powerful and more expensive impact drivers, they may be the proper choice for a DIYer tackling a large project, such as including a room to the house or constructing a large deck.

Torque & Impact

In this best impact drive buying guide, this is another crucial thing to be discussed. Impact drivers are all about torque that gets usually specified in inch-pounds of the tool’s turning power. As a basic rule, the more battery power, the more torque, which is why 18- or 20-volt agencies handle more complicated wood much more quickly than a 12-volt impact motorist.

A lightweight 12-volt impact chauffeur may deliver as little as 800 inch-pounds of torque, while a 20-volt monster may have a maximum capacity of more than 2,000 inch-pounds of torque. For most common DIY jobs, however, the lower-to-midpoint of that range suffices.

Another significant number is the rate at which the impact chauffeur delivers an additional “blow” of power during use. Keep in mind that the manufacturer’s specified ipm is the tool’s “no-load” ipm, suggesting what it provides when run in the air, not driving a screw. Lower-powered impact drivers deliver around 2,000 ipm, while more powerful tools may boast as much as 3,700 ipm.


Another crucial measurement is the impact driver’s rpm, or rotations per minute, describing the bit turns’ speed. Undoubtedly, the faster the rpm, the quicker you’ll do the job, but remember that going too short can strip screws or harm the wood. You’ll also find that as torque boosts, speed decreases. As an average rule, most higher-end impact drivers today have numerous settings for rpm; typically, the most affordable location provides 600 to 800 pm, the middle establishing to 1,800 to 2,000 rpm, and the most excellent setting up to 3,000 or more rpm. This number is typically the tool’s “no-load” capability, suggesting the optimum it can provide when running in the air, not driving a screw.

Frequently Asked Questions For Impact Driver

How does an impact driver work?

Unlike drill/drivers, which use torque at a constant rate, impact drivers supply high-speed bursts of impact– something like a hammer blow– to their torque, creating a very effective turning force far beyond what an average drill is capable of. An impact driver carries a spring, a “hammer,” and an anvil to attain this. The motor spins the shaft, and the spring compresses & launches with great force– think of utilizing your hands to squeeze a big spring together and suddenly letting it go– striking the hammer, which then hits the anvil. That takes place very quickly, usually more than 50 times per second, including bursts of impact to the torque.

Do impact drivers need unique bits?

When bits for impact drivers resemble the bits utilized in a routine power drill, they’re not the same. Though it is safe to use an impact-driver bit in your handheld drill, it isn’t safe to use your routine drill bits in your impact motorist.

Impact-driver bits need to endure the remarkable torque of the tool. Thus, they consist of metal with a bit more versatility than regular bits, which are susceptible to shattering if utilized in an impact driver. Impact-driver bits have a slightly narrower shaft than routine bits. The ending of an impact-driver bit is hexagonal, unlike a rounded lot of most regular bits.

Do impact drivers have torque settings?

You may get shocked to learn that a tool that’s all about torque does not have a setting letting you set the torque level. However, that’s the truth of impact drivers. Unlike numerous drill/drivers, which frequently do have torque settings, impact drivers are primarily an all-or-nothing tool. That’s why they are best conserved for tasks needing significant force to drive screws through complex products or for jobs where the high speed of these practical tools will come in useful.
