Price the correct power system
DCS389B is a 60V MAX saw, so ordinary 20V MAX batteries are not the working power source. That distinction can overturn an apparently attractive bare-tool price. It makes the clearest sense for a carpenter who already owns suitable FLEXVOLT equipment and repeatedly needs accessible removal cuts. For occasional work, compare the complete cost with employer equipment, hire or an existing compatible saw.
Output claims have conditions
DeWalt’s comparison with DCS388 uses specified batteries, so the stated power increase is not a blanket result for every pack or material. The documented stroke and variable trigger help identify the format, but do not establish our measured speed or vibration. Match a suitable blade to identified timber or metal and plan support before starting. A demolition saw should not become the default for exposed finish cuts.
When the smaller option is smarter
DCS367B addresses a different problem: limited body clearance on the 20V MAX platform. Buying the larger saw makes sense when recurring accessible demolition warrants the complete loaded arrangement, not because a higher voltage looks more professional. Some manufacturer-hosted comments on the DCS389 page describe other DeWalt saws; we exclude those from exact-model quotations rather than turning older-tool praise into evidence for this machine.
