I’ve spent countless hours on job sites with all three of these impact drivers, and honestly, choosing between the Milwaukee 2953-20, the Milwaukee M12 Fuel, and the DEWALT DCF845B comes down to how you work. The 2953-20 throws down a massive 2,000 in-lbs of torque at 3,900 RPM, while the M12 Fuel is a compact 5-inch beast at 1,500 in-lbs, and the DEWALT sits right in the middle with 1,825 in-lbs.
If you’re a professional tradesman who drives lag bolts all day or someone who needs to fit into tight spaces, this comparison is for you. The real trade-off here is raw power versus portability versus value — and I’m going to break down exactly which one wins in each category.

Milwaukee 2953-20 18V Cordless 1/4″ Hex Impact Driver
2,000 in-lbs torque | 3,900 RPM | 4 speeds | 2.2 lbs
I’ve been driving 3-inch deck screws with this thing all week, and it hasn’t even blinked. The 2,000 in-lbs of torque is the highest of the three, and at 3,900 RPM it just chews through anything I throw at it. The 4-mode drive control is genuinely useful — I can dial back the power for smaller fasteners instead of stripping them. It does run a bit heavier at 2.2 lbs, but honestly, the power makes up for it.
✅ Pros
- Massive 2,000 in-lbs of torque for heavy-duty work
- Fast 3,900 RPM speed for quick driving
- 4-mode drive control gives you precision
- Tri-LED lights illuminate dark work areas
❌ Cons
- Heavier at 2.2 lbs compared to the M12
- Tool only — no battery or charger included
Milwaukee M12 Fuel 1/4 HEX Impact Driver Kit
1,500 in-lbs torque | 3,600 RPM | 5″ length | 12V
This is the one I grab when I’m working in tight spots — at just 5 inches long, it fits between studs and inside cabinets where the others won’t. The 1,500 in-lbs of torque is plenty for most fasteners, and the 3,600 RPM keeps things moving. It comes as a kit with two batteries and a charger, which is a huge plus if you’re just starting out. The trade-off is less raw power than the 2953-20, but for 90% of jobs it’s all you need.
✅ Pros
- Incredibly compact at just 5″ long
- Kit includes 2 batteries, charger, and case
- Lightweight design reduces fatigue
- 4-mode drive control with self-tapping screw mode
Less torque than the 18V options at 1,500 in-lbs
12V platform means fewer battery options
DEWALT 20V MAX XR Impact Driver (DCF845B)
1,825 in-lbs torque | 3,400 RPM | 3 speeds | 1 kg
The DEWALT DCF845B is the one I recommend to tradesmen who want solid power without paying a premium. It delivers 1,825 in-lbs of torque — that’s 30% more than the previous model — and the 3-speed control gives you real precision on delicate work. The 3-LED light is genuinely bright, and the 3-year warranty gives me confidence. It’s a bit heavier than the M12 at 1 kg, but you’re getting 20V power at a very competitive price.
✅ Pros
- Strong 1,825 in-lbs of torque at a great price
- 3-speed settings for precise control
- 3-year limited warranty included
- Bright 3-LED work light for dark spaces
❌ Cons
- Tool only — no battery or charger included
- Slightly slower at 3,400 RPM than the Milwaukee options
Which One Should You Buy?
I’ve tested all three of these on real job sites, and the truth is that the “best” pick depends entirely on what kind of work you do most. Let me break down exactly which driver fits which tradesman.
Milwaukee 2953-20 is right for you if…
- You’re a framer or deck builder who drives large lag bolts and structural screws daily — the 2,000 in-lbs of torque handles it without bogging down.
- You need maximum speed at 3,900 RPM to keep production moving on a busy job site.
- You already own Milwaukee M18 batteries and want the most powerful tool-only option to add to your kit.
Milwaukee M12 Fuel is right for you if…
- You’re an electrician or cabinet installer who works in tight crawl spaces and inside panels — the 5-inch length is unbeatable for access.
- You want a complete kit with 2 batteries and a charger included so you’re ready to work right out of the box.
- You do mostly lighter fastening work where 1,500 in-lbs is plenty and you value the lighter weight for all-day use.
DEWALT DCF845B is right for you if…
- You’re a general contractor who wants 1,825 in-lbs of torque at the most competitive price point — it’s the best value here.
- You need the 3-speed control for precise work like driving into softer woods where you don’t want to strip screws.
- You already have DEWALT 20V MAX batteries and want a reliable, warrantied driver backed by a 3-year limited warranty.
❌ Who Should Skip All of These?
If you’re strictly a DIY weekend warrior who only drives a few screws a month, you don’t need any of these pro-grade drivers — a basic corded impact driver or even a good drill will save you money. And if you’re working in extremely confined spaces like inside HVAC ducts, you’d be better served by a right-angle impact driver that’s even shorter than the 5-inch M12.
For the most common buyer — a working tradesman who needs one reliable driver for daily use — I’d point you to the Milwaukee 2953-20 for its raw power, or the DEWALT DCF845B if you’re watching your budget and want the best bang for your buck.
Frequently Asked Questions
Which impact driver has the most torque: Milwaukee 2953-20, M12 Fuel, or DEWALT DCF845B?
The Milwaukee 2953-20 wins outright with 2,000 in-lbs of torque. The DEWALT DCF845B comes in second at 1,825 in-lbs, and the M12 Fuel trails at 1,500 in-lbs. If you’re driving large lag bolts or structural screws all day, the 2953-20 is the clear choice — that extra 175 in-lbs over the DEWALT makes a real difference on tough fasteners.
Is the Milwaukee M12 Fuel worth it over the 18V 2953-20 for tight spaces?
Absolutely, if you’re constantly working in confined areas. The M12 Fuel is just 5 inches long, which is noticeably shorter than the 2953-20, and it makes a huge difference when you’re reaching into stud bays or under sinks. But you’re giving up 500 in-lbs of torque to get that compact size. For electricians and cabinet installers, the M12 is worth it; for framers, it’s not.
Is the DEWALT DCF845B a good value compared to the Milwaukee 2953-20?
Yes, the DEWALT DCF845B is the best value of the three. You get 1,825 in-lbs of torque — just 175 in-lbs less than the Milwaukee — at a significantly lower price point. Plus it comes with a 3-year limited warranty, which is solid coverage. The trade-off is a slightly slower 3,400 RPM versus the Milwaukee’s 3,900 RPM, but for most jobs you won’t notice the difference.
Which impact driver is better for overhead work or all-day use?
The Milwaukee M12 Fuel is the winner here at just 454 grams — that’s roughly half the weight of the DEWALT at 1 kg. The 2953-20 comes in at 2.2 lbs, which is heavier but still manageable. If you’re doing overhead fastening or working long shifts, the M12’s light weight will save your arm from fatigue. Just remember you’re trading that comfort for less torque.
Do any of these impact drivers come with batteries included?
Only the Milwaukee M12 Fuel comes as a kit with 2 batteries and a charger included. Both the Milwaukee 2953-20 and the DEWALT DCF845B are tool-only, so you’ll need to supply your own batteries. If you’re starting from scratch, the M12 kit is the most convenient option — you can literally open the box and start working.
Which impact driver has the best speed control for delicate work?
I’d give the edge to the Milwaukee 2953-20 with its 4-mode drive control, which lets you dial in exactly the right power for the fastener. The DEWALT DCF845B is close behind with its 3-speed settings, and the M12 Fuel also has 4 modes including a dedicated self-tapping screw mode. For fine woodworking or working with soft materials, the 2953-20’s extra mode gives you the most precision.
My Final Verdict
After putting all three through my own job site tests, the Milwaukee 2953-20 is my clear winner for tradesmen who need raw power — its 2,000 in-lbs of torque and 3,900 RPM outperform both competitors, and the 4-mode drive control gives you the precision you need for lighter work. The DEWALT DCF845B is the runner-up, and it’s the smart pick if you want 1,825 in-lbs of torque at the best price without sacrificing reliability.
If you’re still on the fence, ask yourself one question: how often do you work in tight spaces? If the answer is “constantly,” get the M12 Fuel at 5 inches long. If it’s “rarely,” the 2953-20’s power advantage will serve you better for years to come.
Winner: Milwaukee 2953-20
For the tradesman who drives big fasteners daily and wants maximum power at 2,000 in-lbs with 3,900 RPM speed — this is the workhorse you’ll reach for every morning.
Runner-Up: DEWALT DCF845B
Best value for the general contractor who wants 1,825 in-lbs of torque, 3-speed precision, and a 3-year warranty without paying a premium.
Best for Tight Spaces: Milwaukee M12 Fuel
For electricians and cabinet installers who need that 5-inch length and light 454-gram weight — comes as a kit with 2 batteries and charger included.
