One of the first power tools people buy is usually a cordless drill-driver due to its versatility. And that’s good, but we’d argue for also investing in a dedicated impact driver. One can make myriad tasks easier, such as building decks, screwing down plywood, installing tile backer board, or any other job that requires driving long screws into wood.

How Impact Drivers Work
A dedicated impact driver, unlike a drill-driver, has a spring-loaded, quick-release chuck that accepts 1⁄4-inch hex-shank driver bits. This tool is designed to drive wood and sheet-metal screws, but it can also turn a bolt or drill a hole using the appropriate impact-rated bits. Faster than a cordless drill, an impact driver’s compactness makes it easier to handle, especially in tight spots or when you’re standing on a ladder. It drives and removes by applying concussive, rotational force to the screw or bolt head. This delivers significantly more torque than a drill, yet is less likely to twist your wrist if the fastener stops or binds.
When you add an impact driver to your arsenal, you’ll need impact-rated 1⁄4-inch hex bits. Plain 1⁄4-inch hex bits meant for use with a drill/driver may work with an impact driver in a pinch, but will not hold up over time. The selection of hex bits here is comprised of some of the best we’ve tested, designed specifically for impact drivers.

How We Test Impact Drivers
We start off by narrowing down the pool of contenders. We do that by researching the market, surveying user reviews, interviewing product managers and engineers, and relying on our own experience operating these tools. Once we have our testing batch, we use each impact driver to repeatedly drive and remove numerous types of fasteners in different materials. We evaluate them on performance, price, comfort, value, and versatility to determine which we believe will best serve your needs.

The M18 Surge uses a hydraulic drive technology that eliminates metal-on-metal contact, making it much quieter than traditional impact drivers. It also requires less torque, and because the torque is sustained much longer, it can drive tough fasteners faster. The M18 Surge features three speed settings and a dedicated, effective, self-tapping screw mode that helps get screws started and prevents them from stripping out. The cherries on top are the battery gauge and an LED to illuminate your work area.

The One+ comes as part of an affordable drill-driver kit. Having both the drill and driver is handy and saves you from having to switch bits back and forth on jobs that require both. This relatively basic driver will accomplish most tasks you’ll encounter around the house. With its 18 volts and 1,700 inch-pounds of torque, we were able to drive long fasteners and lag bolts, even without pilot holes. We found the variable-speed trigger allowed us to easily manage RPMs from zero to 2,900 at up to 3,800 IPM. The tool has a compact head, measuring 5.5 inches from front to back, which helped reaching fasteners in tight areas. The quick-release chuck seemed a little awkward at first, and we found that it works better on some bits than others.

Kobalt’s XTR Max offers an advanced, assist driving mode for what we consider to be a reasonably priced tool. During our test we noted that assist mode slowed RPMs to help get screws started, while preventing the fasteners from over-tightening as they seated. The XTR has three selectable speed modes to tailor driving for the fastener and material you’re working with. We handily drove all our longer deck screws with the XTR, as well as shorter, self-tapping screws. When we drove the lag bolts, we found it to be competent, straining appropriately for the task. We appreciated the battery level indicator, a feature usually reserved for more expensive models. While the tool head is slightly on the larger size, making it feel slightly clunky in tight spaces, the Cobalt XTR is a solid impact driver for the money.

The 20-volt Atomic is a solid, contractor-quality tool with three driving speeds. Alongside the lowest speed setting (1,000 RPM) is a screw icon that suggests a screw-driving mode. As far as we could tell during testing, it isn’t, and the specs don’t mention anything about it. However, the lower speed does work well for starting screws—especially self-tapping fasteners. Nothing we drove during testing fazed the Atomic much. Long deck and cabinet screws drove equally well, as well as self-tapping screws in metal studs. As with other models we tested, long lag bolts took the most work, but we were able to drive them in steadily without drama using the DeWalt. We measured the length of the compact tool’s head at 4 inches, which is super short—even compared to smaller 12-volt drivers. This means you’ll be able to reach into tighter places than with other models. And tight, dark places bring us to one of our favorite features (noted on other DeWalt drivers we’ve tested, too): lighting. The Atomic has three LEDs oriented around the chuck, which illuminate the work area very well, leaving no shadows.
Pros
- Convenient one-handed chuck
- Advanced drive modes
Cons
- Single LED light may cast shadows
| Power | 24-volt |
|---|---|
| Motor | Brushless |

A relative newcomer to the cordless-tool arena, Flex has aimed high with tools designed for contractors and building trade professionals. As such, its Quick Eject Hex comes equipped with advanced features that make it a versatile performer. We’ve come to appreciate impact tools with special drive modes, and this one comes with five. There are three speeds and two self-tapping screw modes—one for small fasteners, another for large ones. The self-tapping modes proved their worth when we drove screws into metal studs, as we were able to easily start the screws and prevent over-driving them and stripping them out. Teh same for long deck screws. And with its two batteries, we had plenty of juice to finish most jobs. When we drove lag bolts into treated landscaping lumber, we easily drove the heads, cupping the washers we used, deep into the wood. The one-handed chuck on the Flex was unlike any other models we tested. We pressed a button, just above the trigger, to open the chuck and accept or release a bit.

We’ve found 12-volt, compact impact drivers to be super handy and useful. Bosch’s Max is no exception, as it’s become our go-to tool for random tasks that pop up. A low-speed, low-torque setting renders small, delicate jobs (where overdriving a fastener can be a problem) worry-free. In our testing, the Max completed every task, including driving 4.5-inch-long, 3⁄8-inch lag bolts—without pilot holes. It did drive slower and work harder than a larger driver, but it got the job done. And to be fair, Bosch claims this driver is designed to cover 85 percent of the types of driving tasks on professional job sites. So building a deck with it isn’t ideal, but building or hanging cabinets, installing drawer slides, assembling furniture, working on electrical boxes, and taking on any task in a confined space or overhead is fair game.
Pros
- Same quality/warranty as the company’s green tools
- Also uses the same 18-volt batteries

This 18-volt impact driver from Metabo HPT, formerly Hitachi, is part of the company’s new line of black tools. Built with the same quality, and warranty, as its green tools, the black versions strip away some of the advanced features, bringing the cost down. While it’s nice to have multiple driving speeds and modes, they’re not required to get a job done. This basic impact driver has the same torque as its green counterpart and drove all the fasteners in our test well, including 4.5-inch-long lag bolts. We also used it to remove 5⁄16-inch, grade-8 bolts torqued up to 40 foot-pounds.

Visually, Makita’s LXT impact driver is svelte and compact—pull the trigger and you’ll immediately notice the smooth, quiet motor. These are the marks of a tool intended for daily professional use. This is backed up by numerous speed/mode settings for any type of application, although deciphering them may seem daunting at first. There are four speed settings, wood and bolt modes, and two tightening modes that prevent fastener breakage or stripping. Once mastered, these modes help perform repetitive tasks with consistent results.

Hart is a relative newcomer to the cordless-tool game, with a line of affordable models including this 20-volt impact driver kit. The tool head measures just over 7 inches in length, almost 2 inches longer than typical compact tools, so working in tight spaces could be a challenge. And it has a traditional electric motor with brushes, which can wear over time, affecting performance. However, we were able to drive all of the fasteners in our test with this Hart, with the bolts torqued to 40 ft-lb and lag bolts noticeably taxing it. Considering the $70 cost, the performance was appropriate. This Hart is ideal for the budget-conscious and folks who need a driver for occasional use around the home.
Pros
- Compact and light
- One-handed chuck makes changing bits easy
Cons
- Initially, tool balance felt different than others
| Power | 12-volt |
|---|---|
| Motor | Brushless |
| RPM | 3,300 |

The M12 Fuel was capable of driving every fastener the 18- and 20-volt drivers did, including 3⁄8 x 3-inch lag bolts, without a pilot hole. Not an ideal task for this driver, but it got the job done. Two inches shorter than most drivers, with a compact head, the M12 Fuel is great in tight spaces. And a single LED works to light those dark nooks and crannies. We liked the easy-to-use speed/mode selector on the top of the tool, with three speeds and a self-tapping fastener mode. Self-tapping mode starts slower to prevent walking and then backs off as the screw finishes seating. The M12 Fuel is a contractor-quality tool, built to hold up to daily use.
