Verdict: if you already own 20V batteries, buy the bare saw. The cheapest 6-1/2 in saw with an authorized price today is DCS391B ($159.00, Power Tool Store); the compact 4-1/2 in DCS571B costs DCS571B ($149.00, Max Tool). A free-tool promo only beats this if the saw is in its pool.

DCS391B is brushed, DCS565B is brushless XR, DCS571B is a compact 4-1/2 in saw, and DCS577B is the 60V FLEXVOLT 7-1/4 in saw. The 60V saw needs a FLEXVOLT battery to deliver full power: see FLEXVOLT vs 20V MAX.
Saw kits
A saw kit adds a battery and charger. It is only worth the difference if you have neither.
Three ways to get the saw
- You own a battery: buy the bare saw from the table.
- You own none: compare the kit price with the bare saw plus a battery in the own-batteries guide.
- A free-tool promo is live: put the saw into the planner. It checks every promo we track and says so when none applies.
