DeWalt DCD791 vs Milwaukee M18 FUEL Router: Which Cordless Router Wins?
When it comes to cordless routing, the DeWalt DCD791 drill and the Milwaukee M18 FUEL router represent two different tool classes, yet they often get compared by users seeking a versatile drilling and routing solution. The DeWalt DCD791 is a compact, high-performance drill/driver, while the Milwaukee M18 FUEL router is a dedicated plunge router. This comparison guide will help you understand which tool suits your needs based on power, runtime, features, and real-world performance.
1. What Are the Key Differences Between the DeWalt DCD791 and the Milwaukee M18 FUEL Router?
The DeWalt DCD791 is a brushless drill/driver designed for drilling holes and driving fasteners, offering up to 1,914 RPM and 300 in-lbs of torque. It weighs 3.4 lbs with a 5Ah battery and features a compact form factor. The Milwaukee M18 FUEL router, on the other hand, is a dedicated plunge router delivering up to 26,000 RPM for routing, trimming, and shaping. It weighs 5.2 lbs with a 5Ah battery and includes variable speed dial and plunge lock mechanism. The core difference lies in purpose: the DCD791 is for drilling and driving, while the M18 FUEL router is for precision wood shaping.
2. How Do Power and Speed Compare Between the Two Tools?
The DeWalt DCD791 uses a brushless motor that delivers 0-1,914 RPM in high speed mode and 0-550 RPM in low speed mode, with a max torque of 300 in-lbs. It is optimized for drilling and driving applications. The Milwaukee M18 FUEL router features a brushless motor that provides variable speed control from 8,500 to 26,000 RPM, with a constant power output of 1.5 HP equivalent. For routing tasks, the Milwaukee offers significantly higher speed and torque for material removal. However, the DCD791 can handle light routing with a router attachment, but not with the same precision or depth. In raw power terms, the Milwaukee M18 FUEL router is the clear winner for dedicated routing, while the DCD791 excels in drilling and driving tasks.

|---|---|---|
| Motor Type | Brushless | Brushless PowerState™ |
| Max RPM | 1,914 RPM | 26,000 RPM |
| Max Torque | 300 in-lbs | N/A (constant power 1.5 HP) |
| Weight (with 5Ah battery) | 3.4 lbs | 5.2 lbs |
| Collet Size | 1/2-inch (drill chuck) | 1/4-inch and 1/2-inch |
| Variable Speed | Yes (2-speed gearbox) | Yes (8,500-26,000 RPM dial) |
| Price (body only) | £95 / $119 | £165 / $209 |
3. Which Tool Offers Better Battery Efficiency and Runtime?
Both tools use 18V battery platforms. The DeWalt DCD791 is compatible with all DeWalt 20V MAX batteries (also 18V in some markets), and our DeWalt DCD791 Battery Compatibility Guide explains which packs deliver the best runtime. With a 5Ah battery, the DCD791 can drill 100+ holes in 1-inch thick hardwood or drive 300 screws. The Milwaukee M18 FUEL router, using an M18 REDLITHIUM 5Ah battery, provides up to 20 minutes of continuous routing or about 50 linear feet of 1/4-inch deep plunge cuts in oak. The router’s higher power draw reduces runtime compared to the drill. For general drilling work, the DCD791 lasts longer per battery, but for routing, the Milwaukee offers adequate runtime for light to medium tasks. If you need extended routing, consider a larger battery (8Ah or 12Ah) for the Milwaukee.
4. Are There Overheating or Reliability Issues With the DeWalt DCD791?
Some users report that the DeWalt DCD791 can overheat during heavy continuous use, especially when drilling large holes in dense materials. This is a known issue, and our DeWalt DCD791 Overheating: Causes and Fixes article provides solutions, such as using a larger battery or allowing the tool to cool down. Similarly, the Milwaukee M18 FUEL router has electronic overload protection but can heat up during prolonged routing. The DCD791’s compact design may contribute to faster heat buildup. In contrast, the Milwaukee router has better ventilation and a metal housing that dissipates heat more effectively. For reliability, the DCD791’s brushless motor is robust, but users should avoid exceeding the duty cycle. If you experience motor failure, see our DeWalt DCD791 Brushless Motor Failure Guide for diagnosis and repair tips.
5. How Does the Chuck and Accessory System Compare?
The DeWalt DCD791 features a 1/2-inch keyless ratcheting chuck with carbide inserts for improved bit grip. It accepts standard hex and round shank drill bits up to 1/2-inch. For chuck replacement, our How to Replace the Chuck on a DeWalt DCD791 Drill guide offers step-by-step instructions. The Milwaukee M18 FUEL router uses a 1/4-inch and 1/2-inch collet system, which is standard for router bits. The router also includes a plunge base and a fixed base (depending on kit) for different routing styles. Accessories for the DCD791 include a side handle, belt hook, and magnetic bit holder. The Milwaukee router offers a dust collection port and edge guide. If you need versatility for drilling, the DCD791’s chuck system is better for multi-purpose use, while the router is specialized for routing bits. Both tools have proprietary accessory ecosystems, though the DCD791’s chuck is easier to maintain and replace.
6. Which Tool Is Better for DIY and Professional Use?
This comparison often arises because users want a single tool that can drill and route, but neither is a direct standalone solution. The DeWalt DCD791 is an excellent choice for DIYers and professionals who need a powerful drill for general construction, cabinetry, and metal working. It can handle light routing with a router attachment, but depth and precision are limited. The Milwaukee M18 FUEL router is a professional tool for carpenters, cabinet makers, and woodworkers who need plunge routing, edge shaping, and pattern routing. The DCD791 wins in versatility for drilling and driving, while the Milwaukee wins in routing performance. If you already own the DCD791, you can pair it with a dedicated router for heavy routing tasks.
