DeWalt DWE575SB Circular Saw vs DeWalt FLEXVOLT 60V Circular Saw DCS578B

Buy the DWE575SB if you want a saw that runs all day off an outlet and never needs a battery. Buy the DCS578B if you work away from power or already own DeWalt 20V/60V FlexVolt batteries. Both cut 2-9/16 in. deep at 7-1/4 in. and bevel to 57 degrees, and both have an electric brake. The corded saw is the simpler, cheaper-to-own tool; the cordless one is lighter in hand and cuts faster at 5,800 RPM, but you pay for batteries and charger separately.

• Choose the DWE575SB if you cut mostly at a bench or on a jobsite with power, want full power on demand and don't want to manage batteries.
• Choose the DCS578B if you need to cut where there is no outlet, already own FlexVolt batteries, or want a brushless motor and higher blade speed.
