Blade Size, Weight, and Dimensions

Blade Diameter

Edge: Milwaukee M18 Brushless 7-1/4-Inch Circular Saw

The Milwaukee M18 Brushless 7-1/4-Inch Circular Saw features a 7-1/4-inch blade. This larger diameter allows for deeper cutting capacity, which is useful for thicker lumber or structural beams. In contrast, the Milwaukee 2730-20 M18 Fuel 6-1/2-Inch Circular Saw uses a smaller 6-1/2-inch blade. While this limits maximum depth, it often provides better maneuverability in tight spaces. You should choose based on the thickness of materials you cut most often. The larger blade offers more power for heavy cuts, while the smaller one may feel less cumbersome for general framing tasks.

Weight

Edge: Milwaukee M18 Fuel 6-1/2" Brushless Circular Saw

Weight matters when you hold the tool overhead or carry it up ladders. The Milwaukee M18 Brushless 7-1/4-Inch Circular Saw weighs 7.2 pounds. This is slightly heavier than the Milwaukee 2730-20 M18 Fuel 6-1/2-Inch Circular Saw, which weighs 6.8 pounds. The lighter weight of the 2730-20 model reduces fatigue during extended use. If you are doing repetitive cuts throughout the day, the half-pound difference can add up. Both tools are bare, so your final weight will depend on the battery you attach, but the base tool weight favors the smaller blade model for comfort.

Dimensions

Edge: Milwaukee M18 Fuel 6-1/2" Brushless Circular Saw

Physical size affects how easily you can fit the saw into tight workspaces or storage areas. The Milwaukee M18 Brushless 7-1/4-Inch Circular Saw measures 13 inches in length, 11 inches in width, and 7 inches in height. The Milwaukee 2730-20 M18 Fuel 6-1/2-Inch Circular Saw is 6.48 inches in length, 13 inches in width, and 7.46 inches in height. The 2730-20 is significantly shorter in length, which may help with balance and control in confined areas. However, it is wider and slightly taller. You should consider your workspace constraints when deciding which footprint works best for your job site.

Motor Type

Edge: Tie

Both circular saws utilize brushless motors. This technology offers longer life and increased efficiency compared to brushed motors. The Milwaukee M18 Brushless 7-1/4-Inch Circular Saw and the Milwaukee 2730-20 M18 Fuel 6-1/2-Inch Circular Saw both feature this advanced drive system. Brushless motors provide more power and run cooler, which helps maintain performance during heavy use. Since both tools share this core technology, there is no performance advantage in terms of motor type. You get the same efficiency and durability benefits from either choice, making this a neutral factor in your decision.

Features

Edge: Milwaukee M18 Brushless 7-1/4-Inch Circular Saw

Specific features can impact your daily workflow. The Milwaukee M18 Brushless 7-1/4-Inch Circular Saw includes an integrated rafter hook for storage and an integrated dust port on the guard for debris management. It also has an electric brake to stop the blade quickly after release. The Milwaukee 2730-20 M18 Fuel 6-1/2-Inch Circular Saw data does not list these specific features. While both are durable, the 7-1/4-inch model offers more built-in conveniences for organization and safety. If you value quick storage and dust control, the 7-1/4-inch saw provides these tools out of the box.
