Use these battery-powered cordless circular saws when portability is a priority, as these saws do not require access to an outlet or generator to operate. By eliminating tripping hazards and the risk of cutting through cords, cordless tools can help reduce accidents in the work place. Battery chemistry, voltage (power), capacity (amp hours), and recharge time impact the run time and down time for the tool. Battery-operated tools can often share batteries with tools of the same brand and voltage.
These cordless circular saws have low-voltage batteries (under 18V) and are typically lighter and more compact than saws with higher-voltage batteries. These general purpose saws are powerful enough for most intermittent cutting tasks and are suitable for use in tight spaces.
Bosch — 18V
DeWalt — 18V (XRP Series)
Makita — 18V (LXT Series)
Milwaukee — 18V (M18 Series)
The high-voltage batteries (18V or more) on these cordless saws provide more power for demanding applications compared to tools with lower-voltage batteries. Although some models may have a compact design, these tools are typically heavier and larger than tools with lower-voltage batteries.
20V — Max Series
28V — M28 Series
36V — LXT X2 Series (Requires 2 18 V Li-ion Batteries)
Featuring high-performance brushless motors, these cordless circular saws are typically smaller and lighter than comparable tools with a standard motor, which helps reduce fatigue when using the tool for long periods of time. Brushless motors do not lose energy through friction and heat and are generally more efficient and durable than standard motors. These professional-grade tools are suitable for heavy, frequent use in construction and assembly operations.
12V — M12 Fuel Series
18V — M18 Fuel Series
The 12V battery on these lightweight, compact circular saws make them a good choice for trimming plywood and flooring or cutting vent holes in sheetrock. They use a smaller blade than larger saws, which reduces the weight of the tool but also decreases its capacity.
