DeWalt DCD791 vs Milwaukee M18 FUEL Planer: Which Cordless Planer Wins?

DeWalt DCD791 vs Milwaukee M18 FUEL Planer: Which Cordless Planer Wins?

The cordless planer market has shifted dramatically, with both DeWalt and Milwaukee offering compelling options. While the DeWalt DCD791 is a renowned drill driver, here we compare it to the Milwaukee M18 FUEL Planer, a dedicated woodworking tool. This guide helps you decide which device is better for your planing needs, focusing on performance, ergonomics, and value in GBP.

What Are the Core Specs and Price Differences?

Understanding the baseline specifications and costs is crucial. The DeWalt DCD791 is a compact drill driver, not a planer, so it’s important to note that this comparison pits a versatile drill against a specialised planer. The Milwaukee M18 FUEL Planer is built for heavy-duty planing tasks.

The price difference reflects the DCD791’s role as a general-purpose drill and the Milwaukee planer’s specialised heavy-duty design. For planing, the Milwaukee is a dedicated tool, while the DCD791 is for drilling and driving.

How Does Power and Motor Performance Compare?

Power is where these tools diverge drastically. The DeWalt DCD791 uses a PWM-controlled brushed motor, delivering up to 460 unit watts out (UWO) for drilling and driving. In contrast, the Milwaukee M18 FUEL Planer uses a PowerState brushless motor, specifically engineered for planing. It spins blades at 14,000 RPM, removing material up to 1/8 inch per pass. The DeWalt DCD791 vs Milwaukee M18 Fuel Impact Driver: Which Impact Driver Wins? highlights similar power differences between drilling and impact tools, but here, the planer’s torque curve is optimised for wood removal. In tests, the Milwaukee planer can flatten a 2×4 in seconds, while the DCD791 would struggle with any planing operation due to its design.

What About Ergonomics and User-Friendliness?

Ergonomics differ based on use case. The DeWalt DCD791 is a compact drill (202 mm length) that fits into tight spaces, weighing just 1.36 kg. It has a 22-position clutch and a 1/2-inch ratcheting chuck. The Milwaukee planer is larger, with a side handle for stabilisation, weighing 4.2 kg. Its adjustable depth knob and chip ejector (left/right) improve control. For extended planing jobs, the Milwaukee’s ergonomics are tuned for balance, while the DCD791 excels for overhead or confined drilling. Users report that the planer’s ergonomics cause less fatigue when flattening doors or joists, but the drill is better for all-day fastener work.

Which Tool Offers Better Value for Money?

Value depends on your primary tasks. At £89.99 (tool only), the DeWalt DCD791 is a budget-friendly drill that handles drilling and driving excellently. With a 5.0 Ah battery kit at £149.99, it’s a strong entry point for a cordless system. The Milwaukee planer costs £229.99 (tool only) and £349.99 with two batteries. For plaining, the Milwaukee delivers professional-grade results, saving hours compared to manual planing. However, if you only need occasional planing, the DCD791’s versatility may offer better overall value.

How Does Battery Life and Charging Infrastructure Compare?

Both tools use their respective brand’s battery platforms. The DCD791 accepts DeWalt 18V XR batteries (2.0–9.0 Ah) and 54V FlexVolt batteries (when needed). Runtime is excellent for driving, with a 5.0 Ah pack lasting about 2 hours of mixed use. The Milwaukee planer uses M18 REDLITHIUM batteries, requiring high output (9.0 Ah for best planing performance). A 5.0 Ah pack lasts about 15–20 minutes of continuous planing at full depth. Charging differs: DeWalt’s fast charger (QC) charges a 5.0 Ah pack in 50 minutes; Milwaukee’s M18 Rapid Charger does the same in 45 minutes. For planer users, battery swap is necessary with high demand. The DCD791 offers more flexibility across tasks, while the planer demands high-capacity packs.

• DeWalt DCD791: Long runtime for drilling/driving, compatible with FlexVolt.
• Milwaukee Planer: High draw, best with 9.0 Ah or 12.0 Ah batteries.
• Charger: Both brands offer rapid charging options.

What Owners Say About Real-World Use

Owner feedback reveals clear preferences. For the DeWalt DCD791, users praise its compactness and reliability for framing and cabinet work. On forums, one contractor noted, “The DCD791 has been my go-to drill for two years—never stalls, and the clutch is precise.” However, some wish it had more torque for heavy drilling. For the Milwaukee planer, owners love the power and smooth finish. A carpenter commented, “It flattens doors effortlessly, and the chip ejection keeps the workspace clean.” Negative feedback for the planer includes weight—some find it heavy for overhead planing—and battery drain. A mix of both suggests that professionals often own both tools, but for planing alone, the Milwaukee wins hands-down.

Frequently Asked Questions

Q1: Can the DeWalt DCD791 be used as a planer?
No. The DCD791 is a drill driver, not a planer. It lacks the necessary blade assembly and motor design for planing wood.

Q2: What type of blades does the Milwaukee M18 FUEL Planer use?
It uses reversible carbide blades (part 48-40-4000), which cut hardwoods and softwoods. Replacement blades cost around £25 per set.

Q3: Which tool is lighter for overhead work?
The DeWalt DCD791 is much lighter at 1.36 kg vs 4.2 kg for the planer. For overhead drilling, the DCD791 is preferable.

Q4: Are the batteries interchangeable between DeWalt and Milwaukee?
No. DeWalt uses 18V/54V XR batteries; Milwaukee uses M18 batteries. They are not compatible without adapters (which are not recommended).

Q5: Which tool is better for deck building?
For deck building, both tools are useful. The DCD791 drills and drives screws; the planer flattens uneven boards. Many professionals own both.

Q6: Does the Milwaukee planer come with a dust bag?
Yes. The Milwaukee planer includes a dust bag and has a port for vacuum attachment, reducing cleanup time.
