DeWalt FLEXVOLT 60V Circular Saw DCS578B vs DeWalt DCS573

Both are DeWalt 7-1/4 in. brushless cordless saws with electric brakes and 57-degree bevels. The DCS578B runs on 60V FLEXVOLT packs and delivers more power and speed, so it suits heavy framing and repeated ripping. The DCS573 is a 20V MAX tool with FLEXVOLT Advantage, lighter and easier to handle for trim and light framing. Owners of the 20V saw report shoe alignment and tracking problems, and its rating is weak, so the 60V saw is the safer pick when the work is demanding.

• Choose the DeWalt FLEXVOLT 60V MAX DCS578B if you cut thick stock and framing lumber all day and want the most power and speed DeWalt's cordless line offers.
• Choose the DeWalt DCS573 if you already own 20V MAX batteries and want a lighter saw for trim, siding and occasional framing.
