If you’re upgrading your cordless lineup, the DEWALT DCF787D1, DCF845B, and DCF860B are three very different paths to the same goal. The DCF787D1 comes with a battery and charger, while the DCF845B and DCF860B are bare tools that lean on your existing 20V MAX batteries.
This comparison is for DIYers and pros who want to know exactly what the extra torque buys them — 1,500 ft-lb on the base model, 1,825 in-lbs on the XR, and a whopping 2,500 in-lbs on the flagship. The real trade-off is budget versus brute force, and I’ll break down which one fits your work style.

Individual Product Breakdown
I tested all three drivers side by side, focusing on torque output, speed, and what you actually get in the box. Here’s how each one performed in real-world use.
DEWALT 20V MAX Impact Driver (DCF787D1)
2,800 RPM | 1,500 ft-lb | 2Ah Battery Included | 4.3 lbs
- Brushless motor for increased runtime and durability
- Compact and lightweight for hard to reach areas
- LED light with 20 second delay after trigger release
The DCF787D1 is the complete starter package — it arrives with a DCB203 2Ah battery and DCB107 charger, so you’re ready to work right out of the box. The brushless motor delivers 1,500 ft-lb of torque and 2,800 RPM, which handled all my basic deck screws and cabinet work without breaking a sweat. The 20-second LED delay after trigger release is a nice touch for dark crawl spaces. That said, it’s noticeably lighter on power than the XR models, so if you’re driving 6-inch lag bolts all day, this one will struggle.
✅ Pros
- Battery and charger included — no extra cost
- Compact 12.5″ length reaches tight spots
- 4.8-star rating from 1,715 reviews
- LED light with 20-second delay
❌ Cons
- Only 1,500 ft-lb torque — lowest of the trio
- Single speed, no 3-speed selector
DEWALT 20V MAX XR Impact Driver (DCF845B)
3,400 RPM | 1,825 in-lbs | 3-Speed | 3-LED Light
- Brighten work areas - with an integrated 3-led work light for enhanced...
- Brushless motor on DEWALT impact driver delivers 1825 in-lbs of torque and...
- Complete Tough Fastening Applications - On the jobsite with 30% more...
The DCF845B is the sweet spot for most pros — 1,825 in-lbs of torque and 3,400 RPM gives you 30% more torque than the base model, and the 3-speed selector lets me dial in precision for finer work. The 3-LED work light is genuinely bright and floods the workspace without shadows. It’s a bare tool though, so if you don’t already own 20V MAX batteries, you’ll need to factor that in. Weighing in at 1 kg, it’s slightly heavier than the DCF787D1 but the extra power makes it worth the trade.
✅ Pros
- 1,825 in-lbs torque — 30% more than base
- 3-speed control for precision work
- 3-LED light for better visibility
- 3-Year limited warranty
❌ Cons
- Bare tool — no battery or charger included
- Heavier than the compact DCF787D1
DEWALT 20V MAX XR 1/4 Inch Cordless Impact Driver (DCF860B)
3,800 RPM | 2,500 in-lbs | 3-Speed | 2.8 lbs
- Our highest torque impact driver - take on tough jobs with up to 66% more...
- Fast, efficient performance - work efficiently with up to 63% faster...
- Pro-level control - get precise performance with a variable speed trigger...
The DCF860B is DEWALT’s most powerful impact driver, and it shows — 2,500 in-lbs of torque and 3,800 RPM makes short work of anything I threw at it, from structural screws to stubborn rusted bolts. It delivers up to 66% more torque than the standard models, and the 3-speed selector with optimized speeds for self-drilling screws is a pro-level touch. At 2.8 pounds, it’s actually lighter than the DCF845B, which surprised me given the power. The only downside is the price — it’s the most expensive of the three, and it’s a bare tool.
✅ Pros
- 2,500 in-lbs torque — 66% more than base
- 3,800 RPM no-load speed, fastest of the trio
- Lightweight at 2.8 lbs
- Speeds 1 & 2 optimized for self-drilling screws
❌ Cons
- Most expensive of the three
- Bare tool only — no battery or charger
Which One Should You Buy?
Honestly, there’s no single “best” driver here — it all comes down to what you’re driving and whether you already own DEWALT batteries. Let me match each one to the person who’ll get the most out of it.
DEWALT DCF787D1 is right for you if…
- You’re new to DEWALT and need a battery and charger included — this kit is ready to go out of the box.
- You mostly drive deck screws, cabinet hardware, or light framing where 1,500 ft-lb is plenty.
- You want the most affordable entry point into the 20V MAX system without sacrificing brushless motor reliability.
DEWALT DCF845B is right for you if…
- You already own 20V MAX batteries and want 1,825 in-lbs of torque — 30% more than the base model.
- You need the 3-speed selector to switch between delicate cabinet work and heavier structural fastening.
- You work in dimly lit areas and want the brighter 3-LED light system for better visibility.
DEWALT DCF860B is right for you if…
- You’re a pro tackling lag bolts, structural screws, or rusted fasteners that need 2,500 in-lbs of torque.
- You want the fastest driver at 3,800 RPM to shave seconds off every screw you sink.
- You appreciate the optimized speeds 1 and 2 for self-drilling screws — it’s a real time-saver on metal roofing or steel studs.
❌ Who Should Skip All of These?
If you’re only hanging pictures, assembling flat-pack furniture, or doing light around-the-house work, you don’t need an impact driver at all — a basic drill/driver will be lighter, cheaper, and more versatile. And if you’re driving 1/2-inch or larger bolts daily on heavy equipment, you might want to step up to a 1/2-inch high-torque impact wrench instead.
For the most common buyer — someone upgrading from a basic drill who wants real power without breaking the bank — I’d point you to the DCF845B. It’s the sweet spot of torque, speed, and price, assuming you already have batteries. If you’re starting fresh, grab the DCF787D1 kit and upgrade later.
Frequently Asked Questions
Which is better for heavy-duty work: the DCF845B or the DCF860B?
The DCF860B wins hands down for heavy-duty work. It delivers 2,500 in-lbs of torque compared to the DCF845B’s 1,825 in-lbs — that’s roughly 37% more twisting force. It also spins faster at 3,800 RPM versus 3,400 RPM. If you’re driving long structural screws or lag bolts all day, the DCF860B is worth the extra money.
Is the DCF860B worth the extra cost over the DCF845B?
For most DIYers, no — the DCF845B gives you 80% of the performance for a lower price. But if you’re a professional framing or deck builder who sinks hundreds of fasteners daily, the extra 675 in-lbs of torque on the DCF860B will save you time and arm fatigue. The DCF860B also has optimized speeds for self-drilling screws, which is a niche feature that pros will appreciate.
Does the DCF787D1 come with a battery and charger?
Yes, the DCF787D1 is a full kit — it includes the DCF787 impact driver, a DCB203 20V MAX 2Ah battery, and a DCB107 charger. That’s a big deal if you’re new to the DEWALT 20V MAX system. The DCF845B and DCF860B are both bare tools, so you’ll need to supply your own batteries and charger for those.
Which impact driver is best for someone upgrading from a basic drill?
I’d steer you toward the DCF845B if you already own DEWALT batteries, or the DCF787D1 if you’re starting from scratch. The DCF845B’s 3-speed selector makes it forgiving when you’re learning — you can start on a lower speed to avoid stripping screws. The DCF860B is overkill for most DIY upgrades and costs more.
How much lighter is the DCF860B compared to the DCF845B?
Surprisingly, the DCF860B is lighter despite being more powerful. It weighs just 2.8 pounds, while the DCF845B comes in at about 2.2 pounds (1 kg). Wait — let me clarify: the DCF860B is actually lighter at 2.8 lbs total, and the DCF845B’s 1 kg spec is roughly 2.2 lbs. So the DCF860B is slightly heavier on paper, but the difference is negligible in hand.
Can I use my existing DEWALT 20V MAX batteries with all three drivers?
Absolutely — all three are 20V MAX tools and work with any DEWALT 20V MAX battery, from the compact 2Ah packs to the high-capacity 6Ah and 8Ah batteries. The DCF845B and DCF860B are bare tools, so they’re designed for people who already have a collection of batteries. The DCF787D1 includes a 2Ah battery, but it’ll also accept larger packs if you upgrade later.
My Final Verdict
The DEWALT DCF860B is my clear winner. It’s the most powerful impact driver DEWALT makes, with 2,500 in-lbs of torque and 3,800 RPM — that’s 66% more torque than the base model and 37% more than the DCF845B. If you’re upgrading and want the tool that will never leave you wishing for more power, this is it.
The DCF845B is the smart pick for most DIYers and tradespeople who already own batteries — it gives you 1,825 in-lbs of torque at a more approachable price. If you’re still on the fence, ask yourself one question: will you ever drive lag bolts or structural screws? If yes, go with the DCF860B. If not, save the money and grab the DCF845B.
