What Makes the DeWalt DCD791 and Milwaukee M18 FUEL Jigsaw Head-to-Head?
When it comes to cordless jigsaws for serious woodworking and remodeling, two names dominate the conversation: the DeWalt DCD791 (a compact drill often mistakenly lumped with jigsaws, but here we clarify) and the Milwaukee M18 FUEL Jigsaw. This comparison guide dives deep into the real-world specs, cutting performance, battery life, and user satisfaction of these two tools. We’ll help you decide which cordless jigsaw wins for your shop—whether you prioritize raw power or precision control.
Which Tool Has Better Cutting Performance and Speed?
The Milwaukee M18 FUEL Jigsaw (model 2737-20) delivers a brushless Powerstate motor that generates up to 3,200 strokes per minute (SPM) with a 1-inch stroke length. Its variable-speed trigger and dial let you dial in perfect control from 0-3,200 SPM, making it ideal for cutting hardwood, laminate, and metal up to 1.5 inches thick. The DeWalt DCD791, however, is a compact drill/driver with a max torque of 460 UWO (unit watts out) and 2-speed gearbox (0-550/0-2,000 RPM)—it’s not designed for jigsaw work. For jigsaw-specific performance, Milwaukee’s tool excels with orbital action settings (0-4) for aggressive or clean cuts, while DeWalt’s jigsaw line (e.g., DCS335) offers similar specs but the DCD791 is not a jigsaw. If you need a jigsaw, the Milwaukee is the clear winner here.
Key performance specs:
- Milwaukee M18 FUEL Jigsaw: 0-3,200 SPM, 1″ stroke, 4 orbital settings, cuts up to 1.5″ wood, 0.5″ steel.
- DeWalt DCD791: Not a jigsaw—max 460 UWO torque, 2-speed, 1,700 RPM high speed, 0-550 RPM low speed.
What About Battery and Runtime Differences?
Both tools use 18V/20V Max lithium-ion battery platforms, but with different chemistries. The Milwaukee M18 FUEL Jigsaw comes bare or with a M18 5.0Ah battery (RedLithium) that provides about 45-60 minutes of continuous cutting on a full charge, depending on load and orbital setting. DeWalt’s DCD791 runs on the 20V Max 5.0Ah DCB205 battery, which lasts around 30-40 minutes of heavy drilling—but again, it’s not a jigsaw. For jigsaw comparisons, Milwaukee’s battery system is known for longer runtime due to its efficient brushless motor and intelligent battery management. If you already own M18 tools, the jigsaw shares batteries with over 250 tools. DeWalt’s 20V Max system is also massive, but for jigsaw use, the Milwaukee offers 10-15% more runtime in real-world tests. Both chargers (M18 Rapid Charger vs DeWalt DCB118) charge a 5.0Ah pack in about 60-90 minutes.
| Feature | DeWalt DCD791 (Drill) | Milwaukee M18 FUEL Jigsaw |
|---|---|---|
| Tool Type | Compact Drill/Driver | Cordless Jigsaw |
| Max Speed | 2,000 RPM (high) | 3,200 SPM |
| Stroke Length | N/A | 1 inch |
| Orbital Settings | N/A | 0-4 |
| Battery (Included) | 2x 5.0Ah (typical kit) | 1x 5.0Ah (bare tool often) |
| Weight (with battery) | 3.6 lbs (with 5.0Ah) | 6.2 lbs (with 5.0Ah) |
| Cut Capacity (wood) | N/A | 1.5 inches |
| Price (bare tool) | £149 / $179 | £199 / $249 |
Are the Ergonomics and Build Quality Comparable?
The Milwaukee M18 FUEL Jigsaw features an all-metal gear case and a die-cast steel footplate that resists bending during heavy cuts. Its over-molded handle with rubber grip reduces vibration, and the integrated LED light shines bright on the cut line. The DeWalt DCD791 is a compact drill (only 7.2 inches long) with a rubber over-mold and ergonomic handle, but it’s not built for jigsaw-style use. For jigsaw ergonomics, Milwaukee’s tool has a toolless blade change lever (T-lock) that works in seconds, while DeWalt’s jigsaw models use a similar system. Weight favors the DeWalt DCD791 at 3.6 lbs vs 6.2 lbs for the Milwaukee jigsaw, but that’s because they’re different tool categories. If you need a jigsaw, the Milwaukee offers premium build with a 5-year warranty (limited) vs DeWalt’s 3-year limited. The metal footplate on Milwaukee prevents warping, a common issue with cheaper jigsaws.
Which Tool Offers Better Value for Your Money?
Price is a major factor. The DeWalt DCD791 drill kit (with two 5.0Ah batteries and charger) costs around £299/$349, while the Milwaukee M18 FUEL Jigsaw bare tool is £199/$249. If you need a jigsaw, the Milwaukee provides better value because it’s purpose-built, while the DCD791 is a drill you might already own. For a complete setup, consider that the Milwaukee jigsaw alone is cheaper than most corded jigsaws from top brands. However, if you’re starting from scratch, a cordless jigsaw kit with battery and charger from Milwaukee runs about £329/$399, which includes the tool, one 5.0Ah battery, and a charger. The DeWalt DCD791 kit is more expensive but gives you a versatile drill. For the jigsaw user, the Milwaukee M18 FUEL is the better investment due to its superior cutting power and battery platform.

What Owners Say About These Tools?
On forums and job sites, owners of the Milwaukee M18 FUEL Jigsaw rave about its “smooth, vibration-free cuts” and “excellent battery life”—many say it cuts as well as a corded jigsaw. Users report it handles 1-inch hardwood without bogging down, and the orbital settings are truly distinct. Some complain the tool is slightly heavy (6.2 lbs) for overhead work, but the rubber grip helps. For the DeWalt DCD791 drill, owners love its “light weight and compact design” for drilling in tight spaces, but note it’s not powerful enough for heavy spade bits. One user said, “Great drill, but don’t expect jigsaw performance—it’s a different tool.” The consensus: the Milwaukee jigsaw is a top-tier choice for professionals, while the DCD791 is a best-in-class drill, not a jigsaw. For jigsaw purposes, Milwaukee wins hands down.
Frequently Asked Questions
Can the DeWalt DCD791 be used as a jigsaw?
No, the DeWalt DCD791 is a compact drill/driver, not a jigsaw. It lacks the orbital action, blade mechanism, and stroke needed for jigsaw cutting. Use it for drilling and driving only.
What is the stroke length of the Milwaukee M18 FUEL Jigsaw?
The Milwaukee M18 FUEL Jigsaw has a 1-inch stroke length, which provides efficient cutting with less vibration compared to shorter-stroke models.
Is the Milwaukee M18 FUEL Jigsaw compatible with universal blades?
Yes, it uses T-shank blades (universal) and features a toolless clamp system for quick blade changes. Most aftermarket blades work.
How long does the battery last on the Milwaukee jigsaw?
With a 5.0Ah battery, you can expect 45-60 minutes of continuous cutting in wood, less in metal or hardwood. Factors like orbital setting and material affect runtime.
Does the DeWalt DCD791 have a brushless motor?
Yes, the DeWalt DCD791 features a brushless motor, which improves efficiency and runtime compared to brushed motors. It’s rated for 460 UWO torque.
Which tool is better for cutting curves?
Only the Milwaukee M18 FUEL Jigsaw can cut curves due to its blade design and orbital settings. The DeWalt DCD791 is a drill, unable to cut curves.
