You get 2,500 in-lbs of torque — enough to rip through structural lags that stall other drivers.

If your job involves sinking long structural lags or driving deck screws into dense hardwood all day, this is the one that does not slow down. It delivers 67% more twisting force than the Milwaukee M12 Fuel (which has 1,500 in-lbs), so it powers through without bogging. The brushless (electronically commutated) motor also spins the bit up to 3,800 RPM at no load, meaning it sinks fasteners faster, according to DEWALT, than previous generations. Buyers report an “excellent power-to-size ratio” and say it drives lag bolts and deck screws without bogging, even at full depth. The 5.75-inch body is slightly longer than some compact options, but still relatively short for its power class. It is a bare tool, so you need a 20V MAX battery and charger already — ideal if you are already in the DEWALT ecosystem.

The catch is the size. At 5.75 inches long and 2.8 pounds, it is a touch bulkier than the ultra-compact Milwaukee M12 Fuel (which measures 5 inches and feels noticeably smaller in tight spots). The variable-speed trigger and 3-speed mode selector give you fine control for self-tapping screws, but you trade a bit of that pocket-sized access for the raw torque.

At only 5 inches long, this M12 slides into gaps the DEWALT cannot reach — a clear edge in tight spaces.

When your workspace is behind a stud wall or between joists, every fraction of an inch you save on length means the difference between fitting and not. The Milwaukee M12 Fuel measures just 5 inches from nose to tail — 0.75 inches shorter than the DEWALT DCF860B — and its small, lightweight header seriously reduces fatigue during long overhead tasks. It delivers 1,500 in-lbs of torque (the twisting force you need to drive screws) and spins up to 3,600 RPM in Mode 3, which is plenty for driving large lag screws and stripping out tough fasteners. Owners mention it is “compact but powerful” and one mentioned they drove large lag screws into old studs on a single charge. The kit comes with two batteries and a charger, so you are ready to work right from the start. The Tri-LED light (three small LEDs arranged around the chuck) casts light directly on the work area without shadow from the bit — a thoughtful touch that the DEWALT bare tool does not include. It also features 4-Mode Drive Control with a dedicated self-tapping screw mode to avoid over-torquing flimsy fasteners.

The obvious trade-off is torque. At 1,500 in-lbs, it lags behind the DEWALT by 1,000 in-lbs — so for building a deck with thick timber-lock bolts, you will likely want the extra grunt of the DEWALT. But for everyday construction, cabinetry, and auto work, the Milwaukee’s small size and balanced feel make it a joy to use in tight spots. The 454-gram weight (just a shade over 1 pound) also helps your arm last longer on a ladder.

You get a drill and an impact driver together — both sharing the M18 system that works with over 175 tools.

If you are building a tool collection from scratch or want a matched pair for job-site reliability, this two-tool combo kit from Milwaukee is an efficient entry point into the M18 system. You get the M18 1/2-inch compact brushless drill/driver plus the M18 1/4-inch brushless impact driver, two REDLITHIUM 2.0 Ah battery packs, a multi-voltage charger, and a carrying case. The impact driver delivers 500 in-lbs of torque (inch-pounds, the measure of twisting force) with 3,000 RPM max speed — sufficient for driving screws, assembly work, and light construction.

The design is compact, ideal for overhead work and tight spaces, and the brushless motor (an electronically commutated motor that wastes less power) paired with the REDLITHIUM batteries extends run time noticeably compared to older brushed models. Reviewers mention it is durable and easy to carry, though the impact driver’s 500 in-lbs torque means it is better suited for cabinets and furniture builds than sinking 13-inch timber-lock bolts. Compatible with the broader M18 system, which boasts more than 175 tools, this combo lets you grow your arsenal without buying new batteries.

The main catch is the torque gap compared to the dedicated DCF860B above. At 500 in-lbs versus 2,500 in-lbs, this impact driver is not even in the same power class — it has one-fifth the twisting force. If heavy deck construction or large structural fasteners are your primary use, look elsewhere. For homeowners who need a reliable drill and impact driver pair for general tasks, this combo saves money and keeps one battery platform for both tools.

A variable-speed trigger and an included battery make this a smart pick for the home shop — not for the pro crew.

Ryobi’s ONE+ system is the go-to for homeowners who want decent performance without the premium price. This kit includes the impact driver, a 1.5 Ah (amp-hour) lithium-ion battery, and a charger. The variable-speed trigger helps you avoid over-torquing screws, while the ABS plastic body (acrylonitrile butadiene styrene, a common lightweight plastic) keeps weight down for casual use. Customers note it is “able to remove stuck 15mm bolts with ease” and that the 2 Ah battery runtime (included separately) gives about 3 hours of work before needing a swap.

For the price, you get a solid entry-level driver that handles furniture assembly, picture frames, and even some automotive work. The 18V platform means you can swap batteries with other Ryobi ONE+ tools. Build quality is ABS plastic, which feels less rugged than the magnesium or metal-reinforced housings of pro-grade tools, but it keeps the weight sensible.

The obvious limitation is that the torque spec is not published — so you are trusting real-world word-of-mouth rather than a hard number. The battery capacity is 1.5 Ah, which is fine for light tasks but will need recharging for a full day of deck building. Also, the Ryobi system does not share batteries with DEWALT or Milwaukee, so if you ever upgrade to a pro platform, you start fresh.

A brushless driver with two batteries at a price that is hard to argue with — but it comes from a brand without a proven track record.

For the absolute lowest cost of entry, the LAZYLAND set gives you a brushless (electronically commutated) 17V impact driver with a 140 Nm torque rating (roughly 1,240 in-lbs), two 1500 mAh (milliamp-hour) lithium-ion batteries, a charger, and a selection of bits. The 6.35 mm chuck (1/4-inch hex) lets you swap bits quickly for different screw sizes. The ergonomic grip is comfortable for light tasks, and the built-in LED work light helps in dim conditions like inside a cabinet or under a sink. Reviewers point out it drives screws well for small jobs.

The brushless motor is a plus at this price — it improves efficiency and runtime compared to older brushed designs. The two batteries are nice for continuous work: keep one charging while you use the other. Maximum torque of 140 Nm is enough for furniture assembly, fixing picture frames, and basic electrical work. The set includes a drill bit and a screwdriver bit, so you can start immediately.

The reality check: this is a budget-friendly tool from a less established brand (LAZYLAND). It lacks the proven durability of DEWALT or Milwaukee and is likely best for occasional use around the house. The 17V battery platform is not shared with any major tool system, so you are locked into this brand’s ecosystem. If your work involves heavy construction or daily pro use, invest in a tier above.
