Performance Analysis
Cutting Power
The DCS380B delivers 3,000 strokes per minute at full trigger pull, which is competitive for a brushed 20V recip saw. Based on our spec analysis, that puts it in the same class as the Ryobi P519 and Craftsman CMCS300B for raw speed. Where it stands out is the variable speed trigger, which gives you fine control when cutting near finished surfaces or working with copper pipe. The trigger is smooth and predictable, not the on-off switch feel you sometimes get with budget tools. For cutting through 2x4 lumber, nail-embedded wood, PVC pipe, and copper, the DCS380B is more than capable. Where it starts to struggle is thick hardwood, large-diameter steel pipe, and extended demolition work. If you are tearing out a full kitchen or doing heavy framing demo, the lack of orbital action and the brushed motor will slow you down compared to the DCS382B or Milwaukee 2821-20.Weight and Ergonomics
At 5.9 lbs bare, this is one of the lighter full-size reciprocating saws on the market. That matters more than most specs because recip saws spend a lot of time overhead, at awkward angles, and in tight spaces. Less weight means less fatigue during a full day of remodeling work. The grip diameter is comfortable for medium to large hands, and the shoe pivots smoothly against work surfaces.Blade Clamp
The 4-position keyless blade clamp is the best feature on this saw. Most budget recip saws offer a standard clamp that holds the blade in one orientation. The DCS380B lets you rotate the blade 90 degrees in four positions, which means you can make flush cuts against walls, floors, and ceilings without repositioning yourself or the workpiece. This is a feature that usually shows up on $200+ saws, so getting it here is a genuine value add.Battery Life
The DCS380B runs on DeWalt's 20V MAX battery platform, which means any battery you already own will work. Based on reported runtime data, a 5.0Ah battery gets roughly 100-120 cuts through 2x4 pine before needing a charge. A 2.0Ah compact battery will give you about 40-50 cuts, which is fine for quick jobs but limiting for a full demolition session. We recommend pairing this with at least a 4.0Ah battery for the best balance of runtime and weight.Who Should Buy the DCS380B
This saw is ideal for homeowners and DIYers who need a reliable recip saw for occasional demolition, pipe cutting, pruning, and general remodeling. If you are already invested in DeWalt's 20V MAX platform, the DCS380B is an easy add to the collection at its price point. It is also a solid first reciprocating saw for someone building out their tool kit. If you are a professional contractor doing heavy demolition daily, look at the DeWalt DCS382B or the Milwaukee 2821-20 instead. The brushless motors, orbital action, and longer stroke lengths on those models justify the higher price for professional workloads.How It Compares
The DCS380B sits in the middle of the 20V recip saw market. Compared to the Ryobi P519 (around its current retailer price bare), you get better build quality, the 4-position blade clamp, and a more refined variable speed trigger. Compared to DeWalt's own DCS369B compact recip saw, the DCS380B offers more power and a longer blade capacity, but is heavier and bulkier for tight-space work. Against the Milwaukee 2621-20 (also brushed, similar price), the DeWalt wins on blade clamp versatility and slightly lower weight. The Milwaukee has a marginally longer stroke length at 1-1/8 in. vs the DeWalt's 1-1/8 in., so they are effectively equal on that front.

Does the DeWalt DCS380B have orbital action?
No. The DCS380B is a straight-stroke reciprocating saw. Orbital action, which adds an elliptical motion to the blade for faster demolition cuts, is available on higher-end models like the DeWalt DCS382B and DCS369B. For most DIY tasks including pipe cutting, pruning, and light demo, straight-stroke is perfectly adequate.
Is the DCS380B brushless?
No. The DCS380B uses a standard brushed motor. This means slightly less runtime per charge and the carbon brushes will eventually need replacement after heavy use. DeWalt's brushless recip saws (like the DCS367B and DCS382B) cost more but offer better efficiency and longer motor life. For occasional use, the brushed motor is not a dealbreaker.
Can I cut metal with the DCS380B?
Yes. With a bi-metal or carbide-tipped blade, the DCS380B handles metal pipe, nails, bolts, rebar, and thin steel plate. The variable speed trigger is useful here because you will want to run at lower speeds for metal to reduce heat and blade wear. For serious metal cutting, consider upgrading to a blade rated for the specific material.
What battery should I use with the DCS380B?
Any DeWalt 20V MAX battery works. For the best balance of runtime and weight, a 4.0Ah or 5.0Ah battery is recommended. The compact 2.0Ah batteries work fine for quick tasks but will run out faster during sustained cutting. The larger 6.0Ah and 8.0Ah batteries add runtime but also noticeable weight to an already 5.9 lb tool.
Is the DCS380B good for demolition?
For light to moderate demolition work, yes. It handles removing trim, cutting through nail-embedded lumber, and taking apart old framing efficiently. For heavy demolition like tearing out structural walls, plaster over lath, or full-room gutting, a brushless saw with orbital action will be significantly faster and less fatiguing over a full day.
