Buying Guide: Torque, Battery, Motor and You
An impact driver is fundamentally different from a drill. A standard drill applies steady rotary force to make holes. An impact driver delivers short, rapid bursts of rotational torque, which makes it much better at driving long screws into dense wood or metal.
The impact mechanism also reduces kickback, so the tool doesn't spin in your hand. Understanding the specs helps you pick the right one.
How Much Torque Do You Really Need?
Torque in an impact driver is measured in inch-pounds (in-lbs). The tools we researched span from 1,400 in-lbs (the combo kit's impact driver) to 2,655 in-lbs (the 2655In-lbs model). For context, a standard 1/4-inch impact driver rated at 1,800 in-lbs handles most decking and 3-inch lag bolts with ease.
The DEWALT 20V MAX XR Impact Driver at 2,400 in-lbs gives you headroom for tougher jobs like driving 6-inch Timberlok screws or removing rusted bolts.
If you only hang shelves and build IKEA furniture, 1,400 in-lbs is enough. If you frame decks or work on vehicles, aim for 2,000 in-lbs or more. Higher torque also means more battery drain, so pair a powerful tool with a larger battery pack.
Brushed vs Brushless Motors: What's the Difference?
A brushed motor uses physical carbon brushes that wear down over time, reducing efficiency and generating more heat and noise. A brushless motor uses electronic commutation, which increases efficiency by up to 50%. That means more runtime per charge, less heat, and a longer tool life.
In our lineup, the DEWALT 20V MAX Impact Driver kit (DCF787D1) uses a brushed motor, while the DEWALT XR models and the 2655In-lbs model use brushless motors. If you use the tool more than once a month, the extra cost for brushless is worth it. For very occasional use, brushed is fine.
Battery System and Kit Options
Impact drivers are sold either as bare tools (just the driver) or as kits with batteries and chargers. If you already own a 20V MAX system from DEWALT, a bare tool is cheaper and avoids redundant chargers. If you're new to the platform, a kit like the DEWALT 20V MAX Impact Driver (DCF787D1) gives you everything you need in one box.
Battery capacity is measured in ampere-hours (Ah). A 2.0 Ah battery might last 30-45 minutes of continuous use. A 5.0 Ah pack can last 2-3 hours.
The combo kit's 1.3 Ah batteries are the smallest, so budget for an upgrade if you plan long projects. And remember, lithium-ion batteries degrade over time; store them at room temperature and avoid full discharges if possible.
Speed Settings and Control
Variable speed triggers give you control from a crawl to full power. Some models add dedicated speed modes. The DEWALT 20V MAX XR 1/4 Inch (DCF860B) offers three speeds plus a Precision Drive mode that slows the tool just before the screw seats, preventing overdriving.
This is especially helpful for cabinet work or fine woodworking. The brushed models have a single variable range which gives less control at low speeds.
For delicate work, consider a model with multiple speed settings. For rough framing, a single speed is perfectly adequate.
Who Should NOT Buy Best Impact Driver for the Money
An impact driver is a fantastic tool, but it's not the right purchase for everyone. Buying the wrong tool wastes money and leads to frustration. Here's who should look elsewhere.
You Need a Drill for Making Holes
If your primary task is drilling holes in wood, drywall, or metal, you need a drill, not an impact driver. An impact driver lacks a chuck and cannot accept twist drill bits. It can only accept hex-shank bits.
While you can buy hex-shank drill bits, they are less common and often more expensive. A standard cordless drill is better for hole-making.
What to look at instead: A drill/driver combo or a dedicated drill like the ones in the DEWALT 20V MAX Cordless Drill Impact (DCK240C2) kit. Or, if you already have a drill, that's fine too.
You Need Precision Torque for Small Screws
Impact drivers deliver high torque in bursts. For very small screws in electronics, eyeglasses, or delicate models, the sudden impact can strip threads or break components. A precision screwdriver or a low-torque electric screwdriver is a better choice.
Even with variable speed, it's hard to feather an impact driver gently enough for tiny fasteners.
What to look at instead: A manual multi-bit screwdriver or a rechargeable precision screwdriver with magnetic tips.
You Already Have a Full DEWALT Kit
If you already own a DEWALT 20V MAX impact driver, there's no reason to buy another one unless yours is broken or you need higher torque. The models we reviewed are great, but they won't significantly outperform a tool you already own. Spend that money on a different tool, like a reciprocating saw or a multi-tool, for a more complete capabillity.
What to look at instead: A bare-tool upgrade if your current one is worn out. Otherwise, consider adding a different tool to your collection.
Final Verdict
The best best impact driver for the money is the DEWALT 20V MAX XR Impact Driver (DCF845B). It delivers pro-grade brushless power, three speed settings, and a compact design at a price that undercuts most competitors. It's the smart choice for anyone who already has DEWALT batteries.
Want a ready-to-go kit with a battery and charger? The DEWALT 20V MAX Impact Driver (DCF787D1) is a solid choice for beginners, despite its brushed motor. Need maximum torque for heavy duty work?
The DEWALT 20V MAX XR 1/4 Inch (DCF860B) is the most powerful bare tool in this lineup.
If you're on a tight budget and need a full system, the 2655In-lbs 21V Brushless 1/4" Cordless Impact offers impressive torque for the money, but be aware of the unknown brand reliability. And if you need both a drill and an impact driver for light home use, the DEWALT 20V MAX Cordless Drill Impact (DCK240C2) is a value-packed starter kit.
Before you buy, revisit the Who Should NOT Buy section above. An impact driver isn't for everyone, and the wrong tool can be worse than no tool at all. But if you're driving screws regularly, one of these five picks will serve you well for years.
FAQ
What's the best Impact Driver for the Money overall?
The DEWALT 20V MAX XR Impact Driver (DCF845B) is the best value. It combines a brushless motor, three speed settings, and high torque (2,400 in-lbs) at a fair price for its quality.
How is an impact driver different from a drill?
An impact driver uses rotational force plus concussive hammering to drive screws. It's more powerful for fastening but can't accept regular drill bits. A drill rotates steadily to create holes and can drive screws with less force.
Do I need a brushless impact driver?
For frequent use (once a month or more), a brushless motor is worth it. It offers better efficiency, longer runtime, and less maintenance. For very occasional use, a brushed motor like in the DCF787D1 is fine.
What size battery do I need for an impact driver?
For light home use, a 2.0 Ah battery works well. For heavy projects like deck building, a 5.0 Ah or larger pack is recommended. The combo kit's 1.3 Ah batteries are best for small jobs.
Can I use impact driver bits in a regular drill?
Yes, hex-shank bits (the ones with a 1/4-inch hex base) can be used in a regular drill with a 1/4-inch hex chuck adapter. But impact-rated bits are designed to withstand the concussive forces of an impact driver and may last longer.
