DCS387B: buy the bare tool when its compact access fits the task
Choose the DCS387B when you already own suitable DeWalt 20V MAX power equipment and need a compact reciprocating saw with four-position blade access. That is its clearest buying case: add the saw without paying for a battery-and-charger package you do not need.
If you need the power equipment too, compare DCS387P1 as a complete kit. Also compare the separate brushless DCS367P1 kit when starting a compact setup. Price the working arrangement, then choose the controls and format that fit your rough cuts.
The DCS387B remains listed by DeWalt and its exact Amazon US offer was available new in October 2026. This page focuses on the bare-tool decision and access-related features. Our separate kit review addresses the DCS387P1 purchase when the battery and charger are needed.
The saw offers a compact body, four-position blade clamp, variable trigger, LED and pivoting shoe. The useful question is whether those features make the cut accessible and the complete package economical. This researched assessment does not claim a hands-on speed, endurance or vibration test.
Good reasons to consider it
- Compact format for suitable restricted access
- Four-position blade clamp and tool-free changes
- LED and pivoting shoe support the working setup
What to weigh before buying
- Bare-tool savings depend on existing approved power equipment
- A rough-cutting tool rather than a finish saw
- Do not assign brushless-kit features to this conventional model
The bare-tool value test comes first
Check which approved DeWalt batteries and charger you already own. If they meet the tool instructions and the task, the B package can avoid buying duplicate power equipment. Include any spare pack needed for the work, not just the one available in the drawer.
If the purchase requires a battery and charger anyway, compare the DCS387P1 kit total before ordering separate pieces. A bare tool can look inexpensive while the complete working package costs more. Condition and the actual seller contents also matter. Do not assume the cheapest saw-body listing represents the best value for someone beginning a new platform.
Compact body: access needs more than a length figure
DeWalt describes the saw as designed for confined spaces and fitting between studs. That makes it worth comparing when a conventional long body is awkward. Still check the entire working envelope: required grip, battery projection, shoe and blade movement.
A compact tool fitting into an opening does not prove that the cut path is clear. Inspect behind and beneath the work and identify hidden wiring, pipes and structural elements. If the body fits but the blade cannot travel safely, the access problem remains. A smaller saw is useful only when it can be positioned and controlled through the whole operation.
Four-position clamp: useful orientation, not a finish guarantee
The four-position clamp changes how the blade can be oriented for a permitted cut. DeWalt identifies flush-cutting and positional versatility as reasons for the design. That can matter when the shoe and handle cannot approach the work in one conventional orientation.
Use the exact manual’s installation and operating guidance and check blade retention with power isolated. A changed orientation does not make an unsupported cut stable or guarantee a clean finished edge. A blade can still flex, and its tip still needs clearance. Choose the appropriate blade and support rather than expecting the clamp to turn the reciprocating saw into a precision joinery tool.
Trigger, shoe and light work together with support
The variable trigger allows a controlled start and a suitable speed for the material and blade. The pivoting shoe provides a contact point against the work, while the LED can help illuminate the immediate cutting area. Each is useful, but each has a limited role.
The light does not identify what is hidden inside a wall. The shoe does not clamp loose stock. The trigger does not correct teeth unsuitable for the material. Support the retained piece and offcut, begin under control and let the blade work. Stop and reassess when the material changes or progress suggests a worn blade or a poor setup.
Blade travel is separate from the compact housing
The 1-1/8-inch stroke describes blade movement. Select enough blade length to remain beyond the material through its full travel, while avoiding unnecessary flexible length that reaches an obstruction. Measure the actual cut path and follow the tool and blade guidance.
For old lumber, inspect possible fasteners and select an appropriate blade. For metal, match the material and thickness. For a visible straight panel edge or a fitted joint, compare the appropriate circular, miter or other precision saw. Compactness is an access feature, not a claim that reciprocating cuts become fine-finish woodworking.
Conventional DCS387 and brushless DCS367 are different models
The DCS367P1 comparison is a separate brushless compact kit. Do not transfer its motor description or promotional runtime claims to DCS387B. The DCS387P1 is a different package for the DCS387 saw, which makes it a contents comparison rather than an entirely different tool format.
If considering the brushless kit, judge its complete equipment price and features. A manufacturer runtime claim with another baseline is not a measured DCS387-versus-DCS367 result here. This article does not claim a fixed speed or endurance advantage. Choose the verified package and access arrangement you will actually use.

| Product and buying link | Choose for | Key distinction | Check before buying |
|---|---|---|---|
| DeWalt DCS387B | Adding a compact saw to existing approved DeWalt power equipment | Four-position blade clamp, variable trigger and pivoting shoe | Bare tool; battery and charger excluded |
| DeWalt DCS387P1 kit | Starting without the needed battery and charger | DCS387 saw with DCB205 5.0Ah battery and charger | Confirm exact charger and seller contents |
| DeWalt DCS367P1 brushless compact kit | A new compact-kit purchase where the brushless configuration matters | Brushless DCS367, 5.0Ah pack, charger and bag | Compare exact included equipment and complete current offer |
DCS387B favors a buyer with suitable power equipment already. DCS387P1 supplies a named kit for the same saw. DCS367P1 is a separate brushless model and should be evaluated on its own documentation.
DeWalt DCS387P1 kit: Starting without the needed battery and charger
Compare the P1 kit when the bare tool would need additional power purchases. It is a package decision for the same compact saw, not evidence of different blade access or a brushless upgrade. Verify the current seller’s actual contents and delivery.
Price the kit against the B tool and approved battery and charger separately. Existing equipment can favor the B offer, while a new system can favor the named kit. The useful total is the working purchase rather than a suffix or an advertised saw-body price.
DeWalt DCS367P1 brushless compact kit: A new compact-kit purchase where the brushless configuration matters
Compare the DCS367P1 for its brushless configuration within the same broader DeWalt platform. The maker lists a DCB205 battery, DCB115 charger and kit bag. We do not claim an independently measured speed, runtime or comfort advantage over the DCS387P1.
Prepare the compact saw for a controlled cut
Before changing a blade
Follow the exact battery-removal and blade-change procedure. Inspect the blade and clamp, seat the shank completely and verify the permitted orientation. Check projection through the whole stroke, not only the stationary position.
Select the blade for the actual material and thickness. Resolve an unsuitable blade, damaged clamp or inadequate clearance before starting the cut.
Before the first project cut
Support and secure the work using the prescribed arrangement. Inspect the cutting area and concealed services where relevant. Use the required grip and protective equipment, and keep bystanders outside the work area.
Follow the operating method in the manual. Stop to investigate unusual behavior or loss of control rather than applying more force to an unresolved setup problem.
After use and before storage
Isolate the tool before cleaning. Remove debris using the approved method and inspect the clamp, shoe, blade and power connection for damage. Do not lubricate or modify parts using advice for another saw.
Store the blade protected and the tool dry. Keep the battery and charger in their prescribed environment. Carry an appropriate selection of labeled blades so the kit is ready for the next material.
DCS387B buying questions
Does B include a battery and charger?
No. The linked bare-tool offer excludes them. Compare the P1 kit if needed.
Does a 20V MAX label mean 20V nominal?
DeWalt specifies 20V maximum initial voltage and 18V nominal voltage. The label is not a cross-brand compatibility rule.
What does the four-position clamp add?
It allows different blade orientations for the permitted operation. Follow the exact manual and check support and clearance.
Is DCS387B the brushless DCS367?
No. They are separate models. Do not transfer the DCS367 motor and runtime claims to DCS387B.
Will fitting between studs make every wall cut safe?
No. Identify hidden services and structural concerns and inspect the complete blade path before cutting.
Have you measured cutting speed or runtime?
No. This is a researched buying assessment based on documentation and verified offers.
Buy the bare tool for the equipment you already have
The DCS387B deserves comparison when its compact access and four-position blade clamp solve your rough-cutting task and approved power equipment is already available.
If not, compare the DCS387P1 kit and the separate brushless compact option. Verify the complete contents, blade choice and work support before ordering.
