The DCS391B's 5150 RPM brushed motor cuts through dimensional lumber and plywood with authority, and the magnesium shoe keeps cuts square without adding weight. At this price point, few compact saws offer the same build quality and cutting capability.
Runtime depends on battery size — the saw drains a 2Ah pack quickly, so a 5Ah battery is the practical choice for extended work. The sidewinder design directs dust toward the operator in right-handed use; a shop vac or outdoor cutting reduces the issue.
This saw suits DIY homeowners and remodelers who already own Dewalt 20V batteries and need a cordless option for moderate cutting tasks. If you require all-day runtime or prefer a blade-right layout, a brushless or left-handed model may be more suitable.
💡 Pair with a 5Ah battery for extended runtime; a shop vac or outdoor cutting helps with the side-discharge dust.
Pros
- Strong cutting speed for a cordless saw, handling most framing and sheathing tasks.
- Lightweight magnesium shoe improves cut accuracy and resists wear over time.
- Good value for the build quality and power at a mid-range price.
Cons
- Dust discharge is directed toward the operator during right-handed use
- Battery life is limited with smaller packs; a 5Ah battery is needed for reasonable runtime.
The DCS391B is a well-documented performer for DIY and professional use — just budget for larger batteries and manage the dust.
