The Milwaukee M18 Fuel Rear Handle Circular Saw is now available with an upgraded One-Key tracking system, adding new safety features and dust management options to a tool that already holds a strong reputation on jobsites. This latest version, model 2931, follows the previous 2930 model and introduces Bluetooth connectivity alongside an AutoStop blade brake and VacLink compatibility.
New Features and Safety Improvements
While the basic specs remain largely unchanged compared to the standard model, the 2931 adds three distinct technologies that change how users interact with the saw. One-Key allows professionals to track and monitor their inventory remotely, a feature that helps tool cribs keep close tabs on equipment. The AutoStop blade brake brings the blade to a halt very quickly; in side-by-side testing with the non-One-Key version, the new model stops in under a second, which is a noticeable safety upgrade for users handling thick kerf blades.
Another major addition is VacLink, a Bluetooth system that connects the saw to compatible vacuums. When the user pulls the trigger, the vacuum activates automatically and continues running for a few extra seconds to clear the hose. Pairing the tools is simple, requiring users to press and hold the VacLink button until the lights turn solid green. The manual trigger lock switch replaces the previous thumb safety, and the dust port has been moved to the front of the tool.
Performance and Weight Comparison
Despite the added technology, the core cutting power of the 2931 remains impressive. It utilizes a Powerstate brushless motor that delivers 6,000 RPM and a maximum cut depth of 2 5/8 inches at 90 degrees. This allows for full passes through 3x material and triple-stacked 3/4-inch sheet goods, maintaining high RPM even during difficult cuts. During testing with 2×10 pressure-treated pine and stacks of OSB, the saw handled demanding tasks with clean, efficient results, making it suitable for use with summer wear on the job.
Designers managed to keep the weight down while adding these features. The bare tool weighs 8.9 pounds, and with the 12.0Ah Forge battery, it weighs 12.3 pounds. This is only slightly heavier than the 2930, which tips the scales at 8.8 pounds bare and 12.1 pounds with the same battery. For context, many rear-handle saws in this category are significantly heavier, making the 2931 one of the lighter options available.
Users switching from the older 2830 model might notice the RPM boost and the lighter frame, though the performance difference in practical applications is often subtle.
The bevel capacity remains at 53 degrees with detents for 22.5 and 45 degrees, and depth detents are clearly marked for quick adjustments.
The grip features an overmold for comfort, though the forward pommel could still use more heft.
Model Specifications and Pricing
The Milwaukee 2930 bare tool retails for $299, while the kit with a 12.0Ah Forge battery and charger costs $449. The One-Key version, 2931, is priced at $349 bare tool and $549 for the kit, which includes two 12.0Ah batteries, a charger, and a storage bag. Both models are backed by a 5-year tool warranty and a 3-year battery warranty.
Whether the new model is worth the extra cost depends on the user’s specific workflow. For a first-time buyer, the 2930 is a solid choice. For someone upgrading from the 2830, the benefits are lighter weight and slightly faster speeds, which might not justify the price tag unless the older tool is heavy. The One-Key model offers useful tracking and safety features for those who value that connectivity, making it a viable option for professionals who rely on those tools to manage their inventory, similar to how they might use a compact vacuum for cleaning.
