Manualsnet found that the Milwaukee M18 FUEL 2746 utilizes a nitrogen air spring mechanism to deliver zero ramp-up time, enabling it to fire up to 3 nails per second with consistent power. The tool features a brushless motor and accepts an 18-gauge capacity of 5/8 inch to 2-1/8 inches in lengths, holding 110 nails for extended workflow efficiency. However, TeamDIYNow identified that the Gen 2 version suffers from severe jamming when using DeWalt brad nails, requiring users to switch to brands like Hitachi or Porter Cable to avoid constant blockages. Additionally, achieving consistent depth requires strict hand pressure against the workpiece to prevent kickback from affecting nail set. This cordless nailer fits professionals seeking pneumatic-like speed and reliability but demands compatible fasteners and disciplined handling for optimal results.

Nitrogen air spring delivers zero ramp-up time
The Milwaukee M18 Fuel 2746-20 utilizes a nitrogen air spring mechanism to generate the force required for driving nails, a design choice that eliminates the traditional pneumatic compressor's need for pressurization buildup. Manualsnet found this system allows the tool to fire up to 3 nails per second immediately upon activation, providing consistent power with zero ramp-up time between shots. This mechanical approach mimics the instant response of an air-powered nailer while removing the dependency on a bulky external tank and hose setup, making it suitable for fast-paced construction environments where speed is critical.
This immediate firing capability is paired with a brushless motor that ensures longer tool life and more nail-driving power per charge compared to brushed alternatives. The combination of these internal components allows the 2746-20 to maintain performance across various wood densities without the power drop-off often seen in battery-powered tools as the charge depletes. The result is a cordless brad nailer that offers the reliability and raw output expected from professional pneumatic equipment, bridging the gap between portability and industrial-grade performance.
DeWalt nails cause frequent jamming in Gen 2
TeamDIYNow identified that the primary source of operational failure for this specific generation is not mechanical but material-based, specifically regarding nail brand compatibility. The reviewer reported severe and constant jamming when using DeWalt brad nails, noting that a user might only get through half a sleeve before the tool becomes unusable. The jam occurs when a nail gets stuck in the upper feeding mechanism, leading to a situation where the trigger is pulled but no nail is driven into the workpiece, requiring manual intervention to clear the blockage.
This sensitivity appears to be an issue with the tolerances of the Gen 2 version rather than a universal flaw, as TeamDIYNow observed that other brands functioned without incident. The reviewer specifically recommended switching to Hitachi or Porter Cable brad nails, stating they went through many packages of these alternatives without experiencing a single jam. This finding suggests that while the tool is robust, it demands high-quality, dimensionally precise fasteners to operate smoothly, and users relying on budget or incompatible brands will face significant downtime.
Depth adjustment requires consistent hand pressure
While the Milwaukee M18 Fuel 2746-20 features a tool-free depth adjustment dial for quick changes, TeamDIYNow found that achieving consistent nail set depths relies heavily on the user's physical technique rather than just the mechanical setting. The reviewer demonstrated that loosely holding the tool against the wood results in kickback upon firing, which reduces the effective pressure applied to the workpiece and causes nails to sit higher than intended. This variability means that even with a perfectly calibrated dial, inconsistent grip strength leads to uneven finishes.
To resolve this issue without constantly readjusting the mechanical dial, TeamDIYNow advised maintaining exact same pressure against the wood for every single nail. By holding the gun firmly and consistently, users can achieve uniform depth regardless of minor variations in trigger pull or recoil. This finding highlights that the tool's performance is partially dependent on operator discipline, requiring a steady hand to fully utilize the precision offered by its adjustable drive mechanism.
18-gauge capacity fits 5/8 inch to 2-1/8 inches
The Milwaukee M18 Fuel 2746-20 is designed as an 18-gauge brad nailer, a gauge that offers a balance between holding strength and finish invisibility. According to the specifications provided by Manualsnet, the tool accepts nails ranging from 5/8 inch to 2-1/8 inches in length, providing versatility for various carpentry tasks from delicate trim work to more substantial framing components. This range allows users to tackle a wide array of projects without needing to switch tools frequently.
The magazine holds up to 110 nails, reducing the frequency of reloading during extended jobs. The tool-free jam release mechanism further supports workflow efficiency by allowing users to quickly clear any obstructions and resume work with minimal downtime. Combined with the integrated belt hook for convenient storage when not in use, these features are designed to keep professional carpenters moving efficiently on site.
Strengths
- +Fires up to 3 nails per second with zero ramp-up delay due to nitrogen air spring mechanism
- +Tool-free depth adjustment dial allows quick and easy changes for optimal nail placement
- +Brushless motor ensures longer tool life and consistent power output across various wood densities
Watch-outs
- −Highly sensitive to nail brand quality, with specific reports of jamming when using DeWalt brad nails
How it compares
The Milwaukee M18 FUEL 2746 fires up to 3 nails per second with zero ramp-up delay, significantly outperforming the sequential firing speeds typical of pneumatic models like the DEWALT DWFP12231. However, it is highly sensitive to nail brand quality and may jam when using DeWalt brad nails, a compatibility issue not reported for other cordless options in this list.
